The amount of q of water emptied by a pipe varies directly as the square of the diameter d. a pipe 9 inches in diameter will empty 324 gal of water over a fixed time period. assuming the same kind of flow, how many gallons of water are emptied in the same amount of time by a pipe that is 4 inches in diameter?

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

1.true 2.false? ? i think. .

step-by-step explanation:

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
