Acylindrical tank that holds 375 l of water is completely full. a pump removes water at a rate of 0.6 l/s. for how many minutes must the pump work until 240 l of water remain in the tank?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
