question 4(multiple choice worth 2 points) (06.03 mc) the number of goldfish in a tank is 12, and the volume of the tank is 45 cubic feet. what is the density of the tank? 0.27 goldfish per cubic foot 3.75 goldfish per cubic foot 33 goldfish per cubic foot 57 goldfish per cubic foot
Answer
Explanation:
Step1: Recall density formula
Density = $\frac{\text{Number of goldfish}}{\text{Volume of tank}}$
Step2: Substitute values
Number of goldfish = 12, Volume of tank = 45 cubic feet. So density = $\frac{12}{45}$
Step3: Simplify fraction
$\frac{12}{45}=\frac{4}{15}\approx 0.27$
Answer:
0.27 goldfish per cubic foot
