Answer:

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

The length of a shadow of a tree is 9 ft. The distance from the top of the tree to the tip of the shadow is 16 ft. what is the h

Margarita [4]

So for this, you'll be using the pythagorean theorem to solve for the height.

$9^2+b^2=16^2$

Solve the exponents to get $81+b^2=256$

Subtract 81 on each side to get $b^2=175$

Square root each side, and your answer should be $b= \sqrt{175}$ or 13.23 ft
