Answer:
131 in²
Step-by-step explanation:
Let x represent the length of the painting. Given that The width of a painting is 4 inches less than the length. Hence:
Width = x - 4
The area of painting = length * width = x(x - 4) = x² - 4x
The frame that surrounds the painting is 2 inches wide (at the top and bottom, left and right). Hence the total width of the frame = (x - 4) + 2 + 2 = x, the length of the frame = x + 2 + 2 = x + 4
The area of the frame = length * breath = x(x + 4) = x² + 4x
Given that the area of the frame = 240 in², hence:
x² + 4x = 240
x² + 4x - 240 = 0
x = -17.62 and x = 13.62
Since the length cannot be negative, hence length = x = 13.62 inches
Area of painting = x(x - 4) = 13.62(13.62 - 4) = 131 in²

Answer:
9 mg
Step-by-step explanation:
We are told in the question above that:
One serving of Raisin Bran cereal contains 50 percent of the 18 mg Daily Value for iron.
Hence, the amount of iron in 1 serving of Raisin Bran cereal =
50% × 18mg
50/100 × 18 mg
= 9 mg

One afternoon, 27 people withdraw $100 from an ATM. What was the overall change in the amount of money in the machine?
Answer:
The change is a decrease of $2700.
Step-by-step explanation:
Given
Total Number of people = 27
Amount each person withdrew = $100
The total withdrawn amount by 27 people = 100 × 27
= $2700
Let M be the amount of money in the ATM at the beginning.
As $2700 was drawn from the ATM, therefore, the change the amount of money in the machine will be:
M - 2700It means the change is a decrease of $2700.
How can I divide 18/15 without any leftovers
Answer:
You can turn the leftovers into a decimal. the answer you would get would be 1.2.
Step-by-step explanation:
Hope this helps and have a nice day!
Answer:
Calculate out how many times the denominator goes into the numerator. To do that, divide 18 by 15 and keep only what is to the left of the decimal point:
18 / 15 = 1.2000 = 1
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
18 - (15 x 1) = 3
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
1 3/15
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 18/15 as a Mixed Number is:
1 1/5
Which would also equal to 1.2000.

In the triangle shown below, which altitude length can be found without using the Distance Formula? What is the length?
Answer: a.) the altitude from N to line LM 6 units
Step-by-step explanation: Looking at the graph, you can count the units from the point N to the line, or you can find the difference between 4 and -2: 4- (-2) = 6
The altitude from N to LM is 6 units. Therefore, option A is the correct answer.
From the graph, triangle LMN is given.
What is the altitude length?The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.
From the given graph we can see, the altitude from N to LM is 6 units.
Therefore, option A is the correct answer.

An animation shows a beetle crawling in a straight line from the point (0, 10) to the point (28, 84) in 2 seconds. Write
a pair of parametric equations to model the path of the beetle. Which point represents the location of the beetle 5
seconds after starting?
Answer:
It actually (70, 195)
Step-by-step explanation:
The point that represents the location of the beetle 5 seconds after starting are; (70, 195).
How to define Parametric Equations?The pair of parametric equations to model the path of the beetle is;
x(t)= 14t and y(t)= 37t + 10
An animation shows a beetle crawling in a straight line from the point (0, 10) to the point (28, 84) in 2 seconds.
Proving the answer;
At t(0,10), x = 0 and y = 10
Thus;
For X-coordinate;
x(0) = 14(0)
x(0) = 0
Similarly;
For y-coordinate;
y(0) = 37(0) + 10
y(0) = 10
That corresponds with the coordinate t(0, 10).
At t = 2 seconds, we have;
For x-coordinate;
x(2) = 14(2)
x(2) = 28
Similalry, for the y-coordinate;
y(2) = 37(2) + 10
y(2) = 160
Now, At t = 2 seconds, we have;
For x-coordinate;
x(5) = 14(5)
x(5) = 70
Similalry, for the y-coordinate;
y(5) = 37(5) + 10
y(5) = 195
The point that represents the location of the beetle 5 seconds after starting are; (70, 195).

Identify an equation in point-slope form for the line perpendicular to
y=1/4x-7 that passes through (-2,-6).
A. y+6= -4(x+2)
B. y+6= -1/4(x+2)
C. y+2 = -4(x+ 6)
D. y-6=1/4(x-2)
Given:
Equation of line is [tex]y=\dfrac{1}{4}x-7[/tex].
The perpendicular line passes through (-2,-6).
To find:
The point slope form of perpendicular line.
Solution:
We have,
[tex]y=\dfrac{1}{4}x-7[/tex]
On comparing this equation with [tex]y=mx+b[/tex], we get
[tex]m=\dfrac{1}{4}[/tex]
Slope of given line is [tex]\dfrac{1}{4}[/tex].
Product of slopes of two perpendicular of the lines is -1.
So, [tex]Slope\times \dfrac{1}{4}=-1[/tex]
[tex]Slope=-4[/tex]
Slope of required line is -4 and it passes through (-2,-6). So, the point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-(-6)=-4(x-(-2))[/tex]
[tex]y+6=-4(x+2)[/tex]
Therefore, the correct option is A.

A spherical balloon is being deflated at a rate of 5 cubic centimeters per second. At what rate is the radius of the balloon changing at the instant the volume of the balloon 972pi cm^3?
Answer:
0.0048cm/s
Step-by-step explanation:
Volume of the spherical balloon is expressed as;
[tex]V = 4/3 \pi r^3\\[/tex]
dV/dt = dV/dr * dr/dt
Given
dV/dt = 5cm³/s
dV/dr = 4πr²
Since V = 972picm³
972π = 4/3πr³
972 = 4/3r³
4r³ = 972 * 3
r³ = (972 *3)/4
r³ = 729
r = ∛729
r = 9cm
dV/dr = 4π(9)²
dV/dr = 324π
dV/dt = dV/dr * dr/dt
5 = 324πdr/dt
dr/dt = 5/324π
dr/dt = 5/324(3.14)
dr/dt = 5/1017.36
dr/dt = 0.0048cm/s

A curve has equation y = 2xy+ 5 and a line has equation 2x + 5y = 1.
The curve and the line intersect at the points A and B. Find the coordinates of the midpoint
of the line AB
Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0

m = 12
8. -4(3 - 6d) = 9(2d - 2)

w = -5
10. 6t + 3(5t - 4) = 12(2t - 5)

Bryce has 10 bals in a bag, each having a distinct color. He randomly picks a ball from the bag 4 times, with replacement. The expected number of distinct colors among the 4 balls Bryce picks can be expressed as a simplified fraction p q . Find p q.
Answer:
p = 1 ; q = 10,000
Step-by-step explanation:
Number of distinct colored balls = 10
Number of balls picked with replacement = 4
Probability = (number of required outcome / number of total possible outcomes)
Distinct picks :
P(1st) = 1 /10
P(2nd) = 1/10
P(3rd) = 1/10
P(4th) = 1/10
Expected Numbe of distinct color:
P(1st) * P(2nd) * P(3rd) * P(4th)
1/10 * 1/10 * 1/10 * 1/10
= 1/10000
p/q = 1/ 10000
p = 1 ; q = 10,000
