Answer 1

0.40 male cats

10.8 m

21.37 kg

11.61 liters

Step-by-step explanation:

7) If there are 100 animals in the shelter, 64 of them are cats. Out of the 64, 63% are male. So 63/100 * 64 = 40.32 are male cats. So percentage of male cats at the shelter is 0.40.

8) Janet has 4 times the required amount = 4 * 2.7 meters = 10.8 meters.

9) Weight of one package of paper = 4.77 kilograms.

Weight of 4.48 packages = 4.48 * 4.77 = 21.37 kg.

10) Water used per load = 2.47 liters.

Water used per 4.7 loads = 4.7 * 2.47 = 11.61 liters.
