The perimeter of a square must be less than 160 feet. what is the maximum length of a side in feet?

1 answer:

3 0

Perimeter of a square=4*side length
160=4*side length
40=side length
Therefore, 39.99999 (repeating 9s) is the maximum side length in feet for the perimeter to be less than 160. If it was 40 feet as the side length, then it would not be less than 160.

Hope this helps!

An airplane flies into the wind for 5 hours, traveling 900 miles. The airplane then

Musya8 [376]

Answer:

22.5 miles per hour

Step-by-step explanation:

Given system of equations

5(s-w)=900

4(s+w)=900

Set equations equal to each other

5(s-w)=4(s+w)

5s-5w=4s+4w

s-5w=4w

s=9w

Solve for w using the substitution s=9w

4(s+w)=900

4(9w+w)=900

4(10w)=900

40w=900

w=22.5

Therefore, the speed of the wind is 22.5 miles per hour

9. Find the dimensions of the 4 triangular faces of the pyramid. (Height is 55.5 ft)

Minchanka [31]

Answer:

$Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$

Step-by-step explanation:

We have a 4-sided triangular pyramid , where

$Q=\frac{\pi}{2}*H\\P=Q*\sqrt{\frac{1}{2}+\frac{4}{\pi ^{2}}}\\Q=\frac{\pi}{2}*55.5ft=87.18ft\\P=87.18ft*\sqrt{\frac{1}{2}+\frac{16}{\pi ^{2}}}=87.18*0.9515=82.95ft\\$
