The number of boys if the total height of the boys is 26.4 meters and their average height is 1.2 meters the average rate of elevation change in feet per second if a submarine dives 440 feet in 20 seconds

A) Divide the total height by the average height:

26.4 / 1.2 = 22 total boys.

B) Divide total feet by total time:

440 feet / 20 seconds = 22 feet per second.\

Because the submarine is diving the rate would become negative 22 feet per second.

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
