a water hose head filled up 1/7 of a pool after 1/10 of an hour at this rate how many hours would it take to fill the pool

A water hose head filled up 1/7 of a pool after 1/10 of an hour at this rate

⇒     ⇒   of the fool = of an hour

So: It'd take 7/10 of an hour or 42 minutes  to fill the pool

P/s: 7/7 of a pool  = a pool

7/10 of an hour = 42 minutes

Ok done. Thank to me :>

step-by-2step explanation:

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
