Question

ok i really don't understand this :O
Help ?

3. 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?

Answer 1

Volume of tank #1 is 359007 cubic feet.

Answer 2

@jim_thompson5910 if it doesnt bother you, could u help me?

Answer 3

(volume of tank)*(density of killer whales) = number of killer whales allowed

(359007 cubic feet)*(0.000011142 whales/1 cubic foot) = 359007*0.000011142 = 4.000055994

so you're allowed to have 4 killer whales

Answer 4

I multiplied because the goal is to get the units "cubic feet" to cancel leaving the number of whales as the only unit

Answer 5

4 killer whales sounds like a reasonable amount (when thinking of any theme park)

it might be high and 3 might be better. I'm not sure as I'm not a biologist

Answer 6

so u divided by 1 right ?

Answer 7

Yes to cancel the units

Answer 8

yeah 1 cubic foot

Answer 9

density = 0.000011142 whales per cubic foot = (0.000011142 whales)/(1 cubic foot)

Answer 10

When you cancel the units, the only unit left is kill whales

Answer 11

Which is what you are looking for. You want to know the number of killer whales

Answer 12

i see it what u mean and how Jim did it. so this is already in cubic feet?

Answer 13

what is already in cubic feet?

Answer 14

4.000055994 = 4
4 killer whales right there's no cubic feet here.

Answer 15

Yup 4 killer whales. Look at Jims first reply. It explains it

Answer 16

Well thank you both ! :D :)^.^ i understand now how to do this for tomorrows test ! :D

Answer 17

yeah the units for the answer is the number of whales

you're welcome
