This is due by tonight. For #3 the volume of the main tank is 359188.76 cu. ft. Please show how you did the calculations I’m desperate for help!

The volume of 1 tank is 42411.5, and 0 whales are allowed in at any time

Step-by-step explanation:

First off, the average length of a killer whale for a male is 20-26 feet so someone needs to contact PETA, besides the point. The tanks are both congruent half cylinders, this being said the formula to find the volume of a cylinder is πr²h, they are half cylinders so you need to divide the output by 2.

This gives you 42411.5

In order to find how many whales can fit in each tank simply multiply the volume by the "Denisty" of killer whales per cubic foot. You will see that unless you saw a whale in half it is simply not possible. so the technically correct answer is .473 but if you want to be a realist just put "I'm calling PETA"

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
