Question

question 12(multiple choice worth 1 points) (06.03 lc) the volume of a fish tank is 70 cubic feet. if the density is 0.4 \\(\frac{\text{fish}}{\text{feet}^3}\\), how many fish are in the tank? \\(\bigcirc\\) 175 \\(\bigcirc\\) 88 \\(\bigcirc\\) 28 \\(\bigcirc\\) 14

Explanation:

Step1: Recall the density formula

Density ($
ho$) is defined as the number of fish ($n$) per unit volume ($V$), so the formula is $
ho=\frac{n}{V}$. We can rearrange it to find the number of fish: $n =
ho\times V$.

Step2: Substitute the given values

We know that the volume $V = 70$ cubic feet and the density $
ho = 0.4\frac{\text{fish}}{\text{feet}^3}$. Substituting these values into the formula: $n=0.4\times70$.

Step3: Calculate the result

$0.4\times70 = 28$.

Answer:

28 (corresponding to the option with 28, e.g., if the option is labeled as the second one with 28, then the answer is the option with 28, like "The option with 28" or if options are A.175, B.88, C.28, D.14, then C.28)
