Question

Really confused! please help!
The density of a fish tank is 0.5fish over feet cubed. There are 30 fish in the tank. What is the volume of the tank?

60 ft3
120 ft3
6 ft3
15 ft3

Answer 1

so, p=m/v ie. density equals mass over volume. so in this case the "mass" is the number of fish. are you able to solve \[\rho=\frac{m}{v}\] for v, then plug in the values for rho and m?

Answer 2

im sorry.. i moved to a new school so i havnt learned this yet..

Answer 3

oh, well, the formula, you just have to memorize. As for solving, you just solve the formula for the variable v then plug and chug.

Answer 4

it is just like solving for y or x when you have the equation for a line

Answer 5

so would it be B?

Answer 6

No, write out the equation and solve for v

Answer 7

i dont think im getting it right...

Answer 8

Please show your work solving for v here

Answer 9

it should take two steps

Answer 10

the only formulas i know are formulas like midpoint and distance.. im not sure how to do what your asking.. i dont think ive learned this at all

Answer 11

I told you the formula. move the variables around to solve for v

Answer 12

p=30/v?

Answer 13

first you need to make the formula look like v=...

Answer 14

although, mass will equal 30

Answer 15

oh ok..

Answer 16

so.. is the density of the fish v?

Answer 17

no, density is density (p or rho)

Answer 18

ohhhh ok... sorry.. im not very good with math haha

Answer 19

@Directrix sorry for asking you to help me so much..

Answer 20

i think its 15 cubed.. am i right?

Answer 21

I don't think so.

Answer 22

oh..

Answer 23

i multiplied 0.5 by 30 and solved to get volume

Answer 24

wait.. i know what i did wrong!

Answer 25

i got 60..

Answer 26

is it a?

Answer 27

yes 60 is correct.

Answer 28

yay! could you help me with another question?
