Answer:
11^2 + b^2 = 16^2
121 + b^2 = 256
b^2 = 135
b = 3 X q(15)
Step-by-step explanation:
Answer:

In other words, the base must be at least 9 feet long.
Step-by-step explanation:
The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.
Recall that the area of a triangle is given by:

Since we want to area to be at least 36 square feet:

We are given that the height is eight feet. Substitute:

Simplify:

Divide both sides by four. Hence, our inequality is:

In words, this means that the base must be at least 9 feet long.
Average of 2 numbers = (7081+8890)/2 = 7985.5
To answer, I'm assuming "fuel long" means "feet long"
To find the amount of feet to make 5 shelves, we must multiply the amount to make one shelf by 5
1.75 * 5 = 8.75
(1.75 is the decimal form for one shelf)
Because 8.75 is less than 10, he has enough to make 5 shelves
