Compound the interest every month instead of every two months.
Increase the interest rate by 1%.
Let the account increase for one more year.
Increase the starting amount by $100.
Calculations:
If the interest is compounded monthly instead of every two months, the final value would be $1,357.36, which is an increase of $9.18 compared to the original value.
If the interest rate is increased to 6%, the final value would be $1,411.58, which is an increase of $63.40 compared to the original value.
If the account increases for one more year at the same interest rate, the final value would be $1,435.09, which is an increase of $86.91 compared to the original value.
If the starting amount is increased by $100, the final value would be $1,421.61, which is an increase of $73.43 compared to the original value.
A company's sales in Seattle were $410,000 in 2012, while their sales in Portland were $255,000 for the same year. Complete the following statements:
a. Seattle's sales were ___% larger than Portland's.
b. Portland sales were ___ % smaller than Seattle's.
c. Portland sales were ___ % of Seattle's.
Give answers accurate to at least one decimal place.
In 2012, a company made $410,000 in sales in Seattle but only making $255,000 in sales in Portland. Fulfill each of the following claims:
a. Seattle outsold Portland in sales by 60.78%.
b. Portland's sales lagged Seattle's by 60.78%.
c. Sales in Portland were 62.2% of those in Seattle.
a. Seattle's sales were ___% larger than Portland's.
To calculate the percentage difference between the two sales figures, we can use the following formula:
Percentage difference = ((larger value - smaller value) / smaller value) x 100%
Substituting the values, we get:
Percentage difference = ((410,000 - 255,000) / 255,000) x 100%
Percentage difference = 155,000 / 255,000 x 100%
Percentage difference = 0.6078 x 100%
Percentage difference = 60.78%
Therefore, Seattle's sales were 60.78% larger than Portland's.
b. The sales in Portland were ___% less than those in Seattle.
Since Portland's sales were smaller than Seattle's, we can simply use the percentage difference we calculated above to find the percentage by which Portland's sales were smaller:
Portland sales were 60.78% smaller than Seattle's.
c. Portland sales were ___ % of Seattle's.
To calculate the percentage of Seattle's sales that Portland's sales represent, we can use the following formula:
Percentage = (smaller value / larger value) x 100%
Percentage = 0.62195 x 100%
Substituting the values, we get:
Percentage = (255,000 / 410,000) x 100%
Percentage = 62.2%
Therefore, Portland's sales were 62.2% of Seattle's.

Henderson's Hardware has an ROA of 12%, a 8% profit margin, and an ROE of 19%. What is its total assets turnover? Do not round intermediate calculations. Round your answer to two decimal places. What is its equity multiplier? Do not round intermediate calculations. Round your answer to two decimal places.
Answer: We can use the DuPont Model to calculate the total assets turnover and equity multiplier:
ROE = ROA × Equity Multiplier
Equity Multiplier = Total Assets / Total Equity
Profit Margin = Net Income / Sales
Total Assets Turnover = Sales / Total Assets
Given:
ROA = 12%
Profit Margin = 8%
ROE = 19%
To find the Total Assets Turnover:
Profit Margin = Net Income / Sales
0.08 = Net Income / Sales
Net Income = 0.08 x Sales
ROA = 12%
ROA = Net Income / Total Assets
0.12 = 0.08 x Sales / Total Assets
Total Assets Turnover = Sales / Total Assets = 0.08 / 0.12 = 0.67
Therefore, the total assets turnover is 0.67.
To find the Equity Multiplier:
ROE = ROA x Equity Multiplier
0.19 = 0.12 x Equity Multiplier
Equity Multiplier = 0.19 / 0.12 = 1.58
Therefore, the equity multiplier is 1.58.
Note: The total assets turnover and equity multiplier are related to each other through the DuPont model. The product of these two ratios should be equal to the ROE. In this case, 0.67 x 1.58 = 1.06, which is approximately equal to 1.9 (ROE in decimal form). This confirms that our calculations are correct.

The volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³ thus the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.
What is volume?Volume is a measure of the amount of space that an object occupies or contains. It is measured in terms of cubic units, such as cubic metres or cubic centimetres. Volume is a three dimensional measure, which means it takes into account the length, width and height of an object.
The rate at which the water level is rising when the water level is 3 cm can be calculated using the formula for the volume of a pyramid. The formula for the volume of a pyramid is V = (1/3) bh², where b is the area of the base and h is the height. In this case, the base is a square with sides of length 3 cm and the height is 5 cm. Therefore, the volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³.
Since the water is being filled at a constant rate of 45 cm³/sec, then the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec. This is because the water level is rising at the same rate at which the water is being filled, and since the water is being filled at a rate of 45 cm³/sec, the water level is also rising at the same rate. This is why the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.

Therefore, each square has a side length of 1.5 cm. The perimeter of each square is 6 cm.
What is perimeter?Perimeter is the distance around the outside of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.
Here,
To calculate the perimeter of the rectangle, we need to first convert the side lengths to the same units. 1 cm 5 mm is equal to 1.5 cm, so the rectangle has dimensions 3 cm by 1.5 cm.
The perimeter of the rectangle is then:
P = 2(3 cm) + 2(1.5 cm)
= 9 cm
To divide the rectangle into two equal squares, we need to find the side length of each square.

What was the wrestler's weight before he went on his diet?
The wrestler's weight before he went on his diet was 78.0 kilograms.
What is y-intercept?
In the context of a graph of a function, the y-intercept is the point where the graph intersects the y-axis. It is the value of the dependent variable (y) when the independent variable (x) is zero. Geometrically, the y-intercept is the value of the function at the point where it crosses the y-axis.
To determine the wrestler's weight before he went on his diet, we need to find the y-intercept of the linear function that represents his weight gain over time. This is because the y-intercept corresponds to the initial weight of the wrestler, i.e., his weight before he started his diet.
We can use the two data points where the time is 0 (i.e., at the start of the diet) to find the slope of the linear function:
(1.5, 85.8) and (3.0, 93.6)
The change in weight over the time interval of 1.5 to 3.0 months is:
93.6 - 85.8 = 7.8
The change in time over that interval is:
3.0 - 1.5 = 1.5
So the slope of the linear function is:
7.8 / 1.5 = 5.2
Now we can use the point-slope form of a linear function to write an equation for the wrestler's weight gain over time:
y - 85.8 = 5.2(x - 1.5)
where y represents the wrestler's weight and x represents the time in months.
To find the wrestler's weight before he went on his diet, we need to evaluate this equation at x = 0:
y - 85.8 = 5.2(0 - 1.5)
y - 85.8 = -7.8
y = 78.0
Therefore, the wrestler's weight before he went on his diet was 78.0 kilograms.

The demand equation for a popular brand of fruit drink is given by the equation:
Qx=10-5px+0.001M + 10Py
where:
Qx= monthly consumption per family in liters
Px= price perlite of the fruit drink =$2.00
M= median annual family income =$20,000
Py= price per liter of a competing brand of fruit drink = $2.50.
1. Interpret parameter estimates.
2. Calculate the monthly consumptioliterslitres) of the fruit.
3. Suppose that the median annual family income increased to ¢30,000. How does this change your answer to part (b)?
4. Determine the demand function and the inverse demand function.
Answer:
Parameter estimates
The coefficient for Px (-5) suggests that there is an inverse relationship between the price of the fruit drink and the quantity demanded. In other words, as the price of the drink increases, the quantity demanded decreases.
The coefficient for M (0.001) suggests that there is a positive relationship between the median annual family income and the quantity demanded. In other words, as the median income increases, the quantity demanded also increases.
The coefficient for Py (10) suggests that there is a positive relationship between the price of the competing brand of fruit drink and the quantity demanded for this brand. In other words, as the price of the competing brand increases, the quantity demanded for this brand also increases.
Step-by-step explanation:
To calculate the monthly consumption of the fruit drink, we plug in the given values into the demand equation,
Qx = 10 - 5(2) + 0.001(20,000) + 10(2.5)
Qx = 10 - 10 + 20 + 25
Qx = 45 liters per family per month.
Therefore, the monthly consumption of the fruit drink per family is 45 liters.
If the median annual family income increased to $30,000, then the new monthly consumption of the fruit drink per family can be calculated as follows,
Qx = 10 - 5(2) + 0.001(30,000) + 10(2.5)
Qx = 10 - 10 + 30 + 25
Qx = 55 liters per family per month.
Therefore, the monthly consumption of the fruit drink per family would increase from 45 liters to 55 liters per family per month.
To determine the demand function, we need to solve for Qx in terms of the other variables,
Qx = 10 - 5Px + 0.001M + 10Py
Qx - 10Py = 10 - 5Px + 0.001M
Qx = (10 - 5Px + 0.001M) / 10Py
Therefore, the demand function is:
Qx = (10 - 5Px + 0.001M) / 10Py
To find the inverse demand function, we need to solve for Px in terms of Qx.
Qx = 10 - 5Px + 0.001M + 10Py
5Px = 10 - Qx - 0.001M - 10Py
Px = (10 - Qx - 0.001M - 10Py) / 5
Therefore, the inverse demand function is,
Px = (10 - Qx - 0.001M - 10Py) / 5

b) the probability of catching a medium-sized guppy from the tank is 0.1391.
c) the probability of catching a guppy if we randomly select a medium-sized fish from the tank is 0.4375.
d) the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is 0.3206.
e) the probability of catching a fish that is not a goldfish if we randomly select a fish from the tank is 0.6291.
f) 0.1384 is not equal to 0.1391, which indicates that the two events are not independent
Probability is a measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1, with 0 indicating impossibility and 1 indicating certainty.
The explanation to the above probability answer are given below:
a)
From the contingency table, we can see that the total number of medium-sized fish is 96. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized fish is:
Probability of catching a medium-sized fish = Total number of medium-sized fish / Total number of fish
Probability of catching a medium-sized fish = 96 / 302
Probability of catching a medium-sized fish = 0.3182
Therefore, the probability of catching a medium-sized fish from the tank is 0.3182
b)
From the contingency table, we can see that the total number of medium-sized guppies is 42. The total number of fish in the tank is 302. Therefore, the probability of catching a medium-sized guppy is:
Probability of catching a medium-sized guppy = Total number of medium-sized guppies / Total number of fish
Probability of catching a medium-sized guppy = 42 / 302
Probability of catching a medium-sized guppy = 0.1391
Therefore, the probability of catching a medium-sized guppy from the tank is 0.1391.
c)
From the contingency table, we can see that the number of medium-sized guppies is 42, and the number of medium-sized fish is 96. Therefore, the probability of catching a guppy if we randomly select a medium-sized fish is:
Probability of catching a guppy given a medium-sized fish = Number of medium-sized guppies / Total number of medium-sized fish
Probability of catching a guppy given a medium-sized fish = 42 / 96
Probability of catching a guppy given a medium-sized fish = 0.4375
Therefore, the probability of catching a guppy if we randomly select a medium-sized fish from the tank is 0.4375.
d)
To calculate the probability of catching a medium-sized guppy if we randomly select a guppy from the tank, we need to find the number of medium-sized guppies in the tank and divide it by the total number of guppies in the tank.
From the contingency table, we can see that the number of medium-sized guppies is 42, and the total number of guppies is 131. Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is:
Probability of catching a medium-sized guppy given a guppy = Number of medium-sized guppies / Total number of guppies
Probability of catching a medium-sized guppy given a guppy = 42 / 131
Probability of catching a medium-sized guppy given a guppy = 0.3206
Therefore, the probability of catching a medium-sized guppy if we randomly select a guppy from the tank is 0.3206.
e)
From the contingency table, we can see that the total number of non-goldfish is 190 (45 medium goldfish + 70 small guppy + 42 medium guppy + 9 medium gourami + 10 large gourami + 14 small gourami). The total number of fish in the tank is 302. Therefore, the probability of catching a fish that is not a goldfish is:
Probability of catching a fish that is not a goldfish = Total number of non-goldfish / Total number of fish
Probability of catching a fish that is not a goldfish = 190 / 302
Probability of catching a fish that is not a goldfish = 0.6291
Therefore, the probability of catching a fish that is not a goldfish if we randomly select a fish from the tank is 0.6291.
f)
From the contingency table, we can see that the probability of randomly catching a guppy is 131/302, which is approximately 0.4344. Similarly, the probability of randomly catching a medium-sized fish is 96/302, which is approximately 0.3182.
Now, let's consider the joint probability of randomly catching a medium-sized guppy, which we calculated earlier to be 42/302, or approximately 0.1391. To determine if the events are independent, we need to compare the product of the probabilities of the individual events (catching a guppy and catching a medium-sized fish) to the joint probability of the events occurring together.
If the events are independent, then the product of their individual probabilities should be equal to the joint probability:
P(catching a guppy) x P(catching a medium-sized fish)
= P(catching a medium-sized guppy)
0.4344 x 0.3182 = 0.1391
0.1384 is not equal to 0.1391, which indicates that the two events are not independent.

Determine the perimeter of the composite figure.
The perimeter of the figure is approximately 63.6 meters, since the lengths of all the sides add up to the figure's perimeter.
What is perimeter?Perimeter is the total length of the boundary of a closed 2-dimensional shape. In other words, it is the distance around the edge of a shape. The perimeter is usually measured in units such as meters, centimeters, feet, or inches depending on the measurement system used. The perimeter can be calculated by adding up the lengths of all the sides of the shape.
Since opposite sides of a parallelogram are equal in length, the length of the straight side of the first parallelogram is:
Length of first parallelogram = 9m
Similarly, the length of the straight side of the second parallelogram is:
Length of second parallelogram = 11m
Now, let's find the length of the straight side of the semicircle segment. We are given that the other side of each parallelogram gets half of the diameter, which is 17m. Therefore, the length of the straight side of the semicircle segment is:
Length of semicircle segment = 17m / 2 = 8.5m
The lengths of all the sides add up to the figure's perimeter. Let's use P to represent the perimeter. Then:
P = 2 (parallelogram length) + semicircle length
When we replace the values we discovered earlier, we obtain:
P = 2(9m + 11m) + π(17m)/2
= 38m + 8.5πm
≈ 63.6m (using π ≈ 3.14)

A woman weighing 130 lbs drinks 2 mixed drinks (2 oz of liquor mixed with soda) with
dinner between 7-8 pm. At 10 pm she had a glass of wine.What was her BAC at 8 pm?
Answer:
Step-by-step explanation:
The BAC (Blood Alcohol Concentration) of a person depends on several factors, such as the amount of alcohol consumed, the time over which the alcohol was consumed, and the weight and gender of the person. For this problem, we will assume that the woman has a normal metabolism and that the alcohol is completely absorbed into her bloodstream.
To calculate the BAC at 8 pm, we need to know the amount of alcohol that the woman consumed and the time over which she consumed it. We are given that she had 2 mixed drinks between 7-8 pm, which contained a total of 2 ounces of liquor. We are also given that she had a glass of wine at 10 pm, but we don't need to consider this for the BAC at 8 pm.
Using the Widmark formula, we can calculate the BAC at 8 pm:
BAC = (Alcohol consumed / (Body weight x r)) - (0.015 x Hours since first drink)
where r is the gender constant (0.55 for females) and 0.015 is the rate at which the liver metabolizes alcohol.
Plugging in the values we know, we get:
BAC = (2 oz / (130 lbs x 0.55)) - (0.015 x 1 hour)
BAC = 0.0208 - 0.015
BAC = 0.0058
Therefore, the woman's BAC at 8 pm was approximately 0.0058, which is below the legal limit for driving in most states in the US.

The correct graph of the inequality -0.4x - 2 < - 1.2 is option 2.
What is an inequality?Equation containing a relational operator and a linear expression is known as a linear inequality. In a coordinate plane or space, regions that satisfy a linear inequality are defined. A linear inequality defines a half-plane in two dimensions, which, depending on the inequality, can be either above or below a line. A linear inequality defines a half-space in three dimensions, which, depending on the inequality, is either above or below a plane. The goal of optimization problems is to determine the maximum or minimum value of a linear function under a set of constraints, which are typically represented by linear inequalities.
The given inequality is -0.4x - 2 < - 1.2.
-0.4x - 2 < - 1.2
Adding 2 on both sides of the equation we have:
-0.4x < -1.2 + 2
-0.4x < 0.8
-x < 2
x > -2
Hence, the correct graph of the inequality is option 2.

The measure of angle t is 60 degrees. What is the x-coordinate of the point where the terminal side intersects the unit circle?
Therefore, the x-coordinate is 1/2.
What is coordinate?A coordinate is a value that represents a point's position in a given system of reference. In two-dimensional (2D) space, coordinates typically consist of two values, x and y, that represent the point's position along the horizontal and vertical axes, respectively.
Given by the question.
To find the x-coordinate of the point where the terminal side intersects the unit circle, we first need to determine the quadrant in which the terminal side lies based on the angle measure of 60 degrees.
Since 60 degrees is in the first quadrant (0 to 90 degrees), the x-coordinate will be positive.
Next, we can use the fact that the terminal side intersects the unit circle, which means its distance from the origin is 1.
Since the angle measure is 60 degrees, we can construct a right triangle with the terminal side as the hypotenuse, and one leg parallel to the x-axis.
The opposite side to the angle t will be sin (60), and the adjacent side to the angle t will be cos (60).
Using the trigonometric identity cos (60) = 1/2, we can see that the x-coordinate of the point where the terminal side intersects the unit circle is: cos (60) = 1/2.

The opposite sides of a rectangle are equal
So, the values that complete the missing dimensions are
3 ft and 5 ft
Also, we have the area to be
Area = Sum of area of each garden
This gives
Area = 7 * 3 + 7 * 5
Area = 56
The perimeter is the sum of the lengths
So, we have
Perimeter = 7 + 5 + 3 + 7 + 3 + 5
Evaluate

[tex]2 \frac{3}{6} - \frac{1}{3} [/tex]
The mathematical expression to be evaluated is:
[tex]2 \frac{3}{6} - \frac{1}{3}[/tex]
To simplify the expression, we first convert the mixed fraction to an improper fraction:
[tex]2 \frac{3}{6} = \frac{(2 \times 6) + 3}{6} = \frac{15}{6}[/tex]
Substituting this value back into the original expression, we get:
[tex]2 \frac{3}{6} - \frac{1}{3} = \frac{15}{6} - \frac{1}{3}[/tex]
Now we need to find a common denominator for the two fractions:
[tex]\frac{15}{6} - \frac{1}{3} = \frac{15}{6} \times \frac{2}{2} - \frac{1}{3} \times \frac{2}{2} = \frac{30}{12} - \frac{2}{6}[/tex]
We can simplify the second fraction:
[tex]\frac{30}{12} - \frac{2}{6} = \frac{30}{12} - \frac{4}{12} = \frac{26}{12}[/tex]
Finally, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 2:
[tex]\frac{26}{12} = \frac{13}{6}[/tex]
Therefore, the simplified value of the mathematical expression is:
[tex]2 \frac{3}{6} - \frac{1}{3} = \frac{13}{6}[/tex]
Answer:
[tex]2\frac{1}{6}[/tex]
Step-by-step explanation:
First, write the fractions as improper fractions.
[tex]\sf2\frac{3}{6} -\frac{1}{3} \\\\\sf\frac{15}{6} -\frac{1}{3}[/tex]
To, subtract the fractions make the denominators the same.
For that, multiply both sides of 1/3 by 2.
[tex]\sf\frac{15}{6} -\frac{1*2}{3*2} \\\\\sf\frac{15}{6} -\frac{2}{6}[/tex]
Subtract.
[tex]\frac{13}{6}[/tex]
Write it as a mixed number.

The inequality can be solved to get 2 > x, and the graph on the number line can be seen in the image at the end.
How to solve the inequality?Here we have an inequality and we want to sole it, to do so, we just need to isolate the variable in the inequality.
Here we have:
10 > 5x
To isolate the variable we can divide both sides of the inequality by 5, then we will get:
10/5 > 5x/5
2 > x
So x is the set of all values smaller than 2.
That is the inequality solved, to graph this, drawn an open circle at x = 2 and a line that goes to the left. The graph is the one you can see in the image below.
