Question

the number of goldfish in a tank is 22, and the volume of the tank is 56 cubic feet. what is the density of the tank? 0.34 goldfish per cubic foot 0.39 goldfish per cubic foot 1.41 goldfish per cubic foot 2.55 goldfish per cubic foot

Explanation:

Step1: Recall density formula

Density $d=\frac{n}{V}$, where $n$ is the number of gold - fish and $V$ is the volume of the tank.

Step2: Identify values

$n = 22$ (number of gold - fish) and $V=56$ (volume of the tank in cubic feet).

Step3: Calculate density

$d=\frac{22}{56}\approx0.39$ goldfish per cubic foot.

Answer:

0.39 goldfish per cubic foot
