In step 1, you found the volume (in cubic feet) of the main tank. If the maximum density of killer whales per cubic foot is 0.000011142, what is the maximum number of killer whales allowed in the main show tank at any given time? You must explain your answer using words, and you must show all work and calculations to receive credit. My answer for step one was Volume=359,189. I know the volume for Density is mass/volume. So do I just divide 0.000011142 by 359,189?

I meant I know the formula for density is mass/volume.

formula for density is mass/volume D = m/v mis the mass and v is the volume
Unofficialllyy
  • Unofficialllyy
Yeah that's what I said. So I just plug in my answer from step 1, into v and the m is the number given in the problem? (0.000011142)
DecentNabeel
  • DecentNabeel
0.000011142/ 359,189
DecentNabeel
  • DecentNabeel
\[\frac{0.00001}{359189}=2.78405E-11\]

  • Unofficialllyy
Well 359,189 was my rounded answer from step 1. Should I do the whole number?

@jim_thompson5910 can you help? :(

Maybe I didn't get the correct answer for step 1.....I really need help! :(

  • DecentNabeel
the density is 11
Unofficialllyy
  • Unofficialllyy
It said to use the density formula, but the questions is asking what is the maximum number of killer whales allowed in the main show tank at any given time?

you can see it
Unofficialllyy
  • Unofficialllyy
Wait, the problem gave me the density.
Unofficialllyy
  • Unofficialllyy
It says the maximum density of killer whales per cubic foot is 0.000011142.

What is the volume of the main tank? If you want the max. number of killer whales allowed in the main tank, calculate this: (Whale occupational density in Whales per cubic foot) * (Tank volume in cubic feet) Assuming that you found that the tank volume in cubic feet is 179503, then your calculation seems appropriate. Watch those units of measurement! Whalescubic/foot∗cubic.feet=number.of.whales

And I have to figure out what is the maximum number of killer whales allowed in the main show tank that has a volume of 359,189
Unofficialllyy
  • Unofficialllyy
So am I trying to figure out the mass?
Unofficialllyy
  • Unofficialllyy
So does this mean I have \[0.000011142=\frac{ mass }{ 359,189 }\]
jim_thompson5910
  • jim_thompson5910
You found the volume to be 359,189 cubic feet You're given a density of whales per cubic feet. That's how many whales there are in ONE cubic foot. So we need a lot of cubic feet for just one whale. You multiply the two like so |dw:1437266784801:dw|
jim_thompson5910
  • jim_thompson5910
notice how I set up the density so that the "cubic feet" units cancel |dw:1437266871172:dw|
Unofficialllyy
  • Unofficialllyy
and I multiply the two to get 4.00208384
jim_thompson5910
  • jim_thompson5910
oops I meant to write `You're given a density of 0.000011142 whales per cubic feet. `
jim_thompson5910
  • jim_thompson5910
yeah 4.002083838
jim_thompson5910
  • jim_thompson5910
round down to get 4
Unofficialllyy
  • Unofficialllyy
So approx 4 whales to each tank
jim_thompson5910
  • jim_thompson5910
you can have at most 4 whales in the tank
