Answer:

See below in bold.

Step-by-step explanation:

1. x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2. 5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em> </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4. 15/75

Divide top and bottom by 15:

= 1/5.

It takes a hose 2 minutes to fill a rectangular aquarium 12 inches long, 13 inches wide, and 14 inches tall. How long will it ta

rusak2 [61]

Volume of the first aquarium = (12" x 13" x 14") = 2,184 inches³

Volume of the second aquarium = (32" x 34" x 35") = 38,080 inches³

The second aquarium has (38,080 / 2,184) = 17.44 times as much
volume as the first aquarium has.

So it'll take the hose 17.44 times as long to fill the second one

= (17.44) x (2 minutes) = 34.9 minutes.
