Answer:
180 ft
Step-by-step explanation:
We are working to find the perimeter here. Let x represent the length of the room.
We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.
Our equation is now: 2x + 2(70) = 500
Now we have to find x, we'll start by multiplying 70 by 2.
2x + 140 = 500
Now we can solve for x:
Subtract 140 from both sides
2x = 360
x = 180
The length of this room is 180 ft.
2(180) + 140 = 500
360 + 140 = 500
I’m guessing that the 5th percentile is app. 2 standard deviations which I think is right. In that case the 5th percentile will tend to wait for 212+2(24.7)= 261.4 (days?). Hope that helps!

Answer: Commission rate = $30.72
Step-by-step explanation: For this problem we want to find the commission rate for sales that are a total of $768. The commission rate is 4%.
Convert 4% to a decimal. 4/100 = 0.04.
Now, multiply the sales by the decimal 0.04 to find the commission rate.
768 x 0.04 = 30.72, or $30.72 for the commission rate.
