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

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?

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

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.

it is just like solving for y or x when you have the equation for a line
anonymous
  • anonymous
so would it be B?
alekos
  • alekos
No, write out the equation and solve for v
anonymous
  • anonymous
i dont think im getting it right...
FibonacciChick666
  • FibonacciChick666
Please show your work solving for v here
FibonacciChick666
  • FibonacciChick666
it should take two steps

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
FibonacciChick666
  • FibonacciChick666
I told you the formula. move the variables around to solve for v

p=30/v?
FibonacciChick666
  • FibonacciChick666
first you need to make the formula look like v=...
FibonacciChick666
  • FibonacciChick666
although, mass will equal 30

  • anonymous
oh ok..
anonymous
  • anonymous
so.. is the density of the fish v?
FibonacciChick666
  • FibonacciChick666
no, density is density (p or rho)

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

@Directrix sorry for asking you to help me so much..
anonymous
  • anonymous
i think its 15 cubed.. am i right?
Directrix
  • Directrix
I don't think so.
anonymous
  • anonymous
oh..
anonymous
  • anonymous
i multiplied 0.5 by 30 and solved to get volume
anonymous
  • anonymous
wait.. i know what i did wrong!
anonymous
  • anonymous
i got 60..
anonymous
  • anonymous
is it a?
anonymous
  • anonymous
yes 60 is correct.
anonymous

yay! could you help me with another question?
