Answer:
First, we need to figure out how many circular rugs can fit in the living room without overlap.
One way to approach this is to find the area of each circular rug (using the formula A = πr^2, where r = 3 feet since the diameter is 6 feet).
A = π(3)^2 = 28.26 square feet
Next, we can find the area of the living room:
A = 12 x 18 = 216 square feet
To figure out how many circular rugs can fit, we can divide the living room area by the rug area:
216/28.26 ≈ 7.64
Since we can't have partial rugs, we need to round down, which means Shannon can fit 7 circular rugs in her living room without overlap.
The total area covered by the circular rugs would be:
7 x 28.26 = 197.82 square feet
Therefore, the closest answer choice to the nearest square foot is A) 170 ft².
Answer:A
Step-by-step explanation:
She can put 2 circles together width wise because 6+6 = 12
She can put 3 circles together length wise because 6+6+6 = 18
So she can put 6 circles in total.
The area of one circle is found with the equation A=πr^2
The diameter is 6ft, so the radius is 3ft, so
A=π*3ft^2
A=28.26ft²
This is the area of one circle. We need to find the area of 6 because 6 can fit in total.
28.26ft² * 6= 169.56 ft²
Test a claim on three locations ?
The slope constraint for the zip line is 6 to 8 feet of vertical change for every 100 feet of horizontal change.
How to explain the informationSo, if the vertical change is 7 feet, the horizontal change must be between 7/6 and 7/8 of a hundred feet, or between 11.67 and 12.5 feet.
For Zip line A, the horizontal distance is 120 feet. So, the vertical change of 7 feet is within the slope constraint.
For Zip line B, the horizontal distance is 140 feet. So, the vertical change of 7 feet is within the slope constraint.
For Zip line C, the horizontal distance is 150 feet. So, the vertical change of 7 feet is within the slope constraint.
Therefore, LaTisha's claim is correct. The vertical change of 7 feet will satisfy the slope constraint for all three locations.

a rocket is launched in the air. Its height in feet is given by h=-16t^2+128t where t represents the time in seconds after launch. What is the appropriate domain for this solution?
The quadratic function has the following domain: 0 ≤ t ≤ 8.
How to find the domain of a quadratic equation
Herein we find a quadratic equation that models the height of the rocket in time. The domain is the set of all values of t such that all values of h exist.
Mathematically speaking, the domain of quadratic equations is the set of all real numbers, but physically speaking, this domain is formed by the set of all non-negative numbers such that h ≥ 0. The domain is found by algebra properties:
h = - 16 · t² + 128 · t
h = - 16 · t · (t - 8)
Then, the domain of the quadratic function is: 0 ≤ t ≤ 8.

What value of x would make 5 Superscript x Baseline equals 625 true? Enter the answer in the box
The value of x that makes [tex]5^x = 625[/tex] true is x = 4.
To determine the value of x in the equation [tex]5^x = 625[/tex], we need to find the exponent that results in 625 when applied to the base 5.
Since 625 can be expressed as 5 raised to the power of 4 ([tex]5^4 = 625[/tex]), the value of x that satisfies the equation is 4.
When we substitute x = 4 into the equation, we get [tex]5^4 = 625[/tex], which is true.
Therefore, x = 4 is the solution to the equation, indicating that 5 raised to the power of 4 equals 625.

50 Points! Multiple choice geometry question. Photo attached. Thank you!
Answer: D = 100π square units
Step-by-step explanation:
The formula to calculate the circumference of a circle is C = 2πr, where C is the circumference and r is the radius of the circle.
In this case, we have a circumference of 20π units, so we can set up the equation as follows:
20π = 2πr
To find the radius, we can divide both sides of the equation by 2π:
r = (20π) / (2π)
Simplifying further:
r = 10
Now that we have the radius, we can calculate the area of the circle using the formula A = πr^2:
A = π * (10)^2
A = π * 100
A = 100π

x ≤ 8 or x > 10 is the solution of the inequality 11 ≥ 2x - 5 or 2x - 5 > 15.
To solve the compound inequality 11 ≥ 2x - 5 or 2x - 5 > 15, we will solve each inequality separately and then combine the solutions.
Solve the first inequality: 11 ≥ 2x - 5
Add 5 to both sides to isolate 2x:
11 + 5 ≥ 2x
16 ≥ 2x
Divide both sides by 2:
8 ≥ x
So the solution to the first inequality is x ≤ 8.
Solve the second inequality: 2x - 5 > 15
Add 5 to both sides to isolate 2x:
2x > 15 + 5
2x > 20
Divide both sides by 2:
x > 10
So the solution to the second inequality is x > 10.
Combining the solutions, we have x ≤ 8 or x > 10.

Anna wants to determine the height of a right rectangular prism. The prism has a volume of 380 cm³ and a base whose area is 50 cm². She lets h represent the height of the prism.
What equation can she write to solve the problem?
The height of the right rectangular prism is 7.6 cm.
To determine the height of the right rectangular prism, we can use the formula for the volume of a prism:
Volume = Base Area * Height
Given that the volume is 380 cm³ and the base area is 50 cm², we can write the equation as:
380 = 50 * h
Now, let's solve for h by dividing both sides of the equation by 50:
h = 380 / 50
Simplifying the expression:
h = 7.6 cm

Calling card A charges a connect fee of 69¢ plus 1.9¢ perminute. Calling card B has no connect fee but charges 6¢ perminute.
Which system of equations can be used to determine the number of minutes (x) where the price (y) is the same for both cards?
Answer:
16.829 minutes
Step-by-step explanation:
To solve this problem, we need to set up a system of equations based on the given information. Let's define the variables:
Let x be the number of minutes.
Let y be the price in cents.
For calling card A, the price can be calculated using the formula: y = 69 + 1.9x
For calling card B, the price can be calculated using the formula: y = 6x
We want to find the number of minutes (x) where the price (y) is the same for both cards. To set up the system of equations, we equate the two expressions for y:
69 + 1.9x = 6x
Now, we can solve this equation to find the value of x, which represents the number of minutes where the prices are equal.
69 + 1.9x = 6x
To simplify the equation, we can subtract 1.9x from both sides:
69 = 6x - 1.9x
Combining like terms, we have:
69 = 4.1x
To isolate x, we divide both sides of the equation by 4.1:
69 / 4.1 = x
Simplifying the division gives us:
16.829 = x
Therefore, the number of minutes (x) where the price (y) is the same for both calling cards A and B is approximately 16.829 minutes.
Hope this helps!
Answer:
For calling card A: y = 0.019x + 0.69
For calling card B: y = 0.06x
Step-by-step explanation:
For calling card A: y = 0.019x + 0.69
For calling card B: y = 0.06x
Set the prices equal to each other to find when they are the same:
0.019x + 0.69 = 0.06x
Simplify and solve for x:
0.041x = 0.69
x = 16.83 (rounded to two decimal places)
Therefore, if a person expects to talk for 16.83 minutes or more, calling card A will be cheaper. If they expect to talk for less than 16.83 minutes, calling card B will be cheaper.
round 52754.1683 the nearest.ten
Answer:
52750
Step-by-step explanation:
Step 1: Identify the digit in the tens place:
The digit in the tens place is always 2 spaces to the left of the decimal.Thus, the digit in the tens place is 5 (the one sandwiched between 7 and 4).Step 2: Examine the digit to the right of the tens place:
In this case, the digit to the right of the tens place is 4.Step 3: Determine the rounding:
When the digit to the right of the tens place is 5 or greater (5, 6, 7, 8, or 9), you round up the tens place digit by adding 1 to the digit in the tens place.Also, we remove the decimal point and everything to the left of it, using a whole number only.When the digit to the right of the tens place is less than 5 (4, 3, 2, 1, or 0), you keep the tens place digit as it is and the number to right of tens place digit it replaced by 0.We still remove the decimal point and everything to the left of it, using a whole number only.Since the digit to the right of the tens place is 4 (which is less than 5), we keep the tens place digit as is.
Original number: 52754.1683
Rounding to the nearest ten: 52750
Thus, rounding 52754.1683 to the nearest ten gives us 52750.
