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
Answer:
To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius.

3760/7916
reducing this fraction is simplifying it, so that means
3760/7916=940/1979
Answer:
Mean = (19 + 20 + 21 + 22 + 23)/5 = 105/5 = 21
x x - mean (x - mean)^2
19 -2 4
20 -1 1
21 0 0
22 1 1
23 2 4
Sum = 10
