The number of goldfish in a tank is 19, and the volume of the tank is 52 cubic feet. what is the density of the tank?
a) 0.22 goldfish per cubic feet
b) 0.27 goldfish per cubic feet
c) 0.33 goldfish per cubic feet
d) 0.37 goldfish per cubic feet

D.) 0.37 goldfish per cubic feet

Step-by-step explanation:

To find the density of a space, you will need to divide the mass over volume or mass over area. In this case, it's mass over volume. The question gives us what's needed: 19 is our mass and 52 is our volume. So we will divide the two values, which will give us 0.365. We need to round our answer to the nearest hundredth, which will give us the answer D.) 0.37 goldfish per cubic feet.

A word of advice: When it comes down to the dividing part of this problem, please be sure to divide the numbers correctly. When using a calculator, input the smaller number first (19), then the dividing sign, then the larger number (52). This will make a big difference in your answer and make your work less complicated.

Hope this helps :)
