Answer 1

3.

Given:

no. of goldfish in a tank = 22 = mass

volume of the tank = 56 cubic feet

So

Density = Mass/Volume

= 22/56

= 0.39 goldfish per cubic foot.

Answer: 0.39 goldfish per cubic foot.

4.

Given:

Density of Tinyville = 16.2 Tinys per acre.

Population in Tinyville = 405 Tinys.

Let x be total acres of Tinyville.

So

Tinys living in 1 acre = 16.2,

total Tinys living in Tinyville = 405.

So, x = 405/16.2 = 25 acres.

Answer: 25 acres.
