Add the ratio numbers to be your denominator
5+3+7+1=16
Pieces:
5/16 x124=38.75
3/16 x124=23.25
7/16 x124=54.25
1/16 x124=7.75
Answer: The correct answer is 10 piranhas.
Step-by-step explanation:
To calculate the total Volume of a cylinder we have to use the following formula:
Volume = Area * Height
Area = π * r² , where r= radius
The diameter is always the twice the radius so the diameter is 4 feet in this case and the radius is 2 feet so the area is
Area= 3.1416 * (2*2)
Area = 3.1416 * 4
Area = 12.5664 square feet
Volume = 12.5664 (area) * 1.25 (height).
Volume = 15.708 cubic feet
Each piranha needs 1.5 cubic feet so we have to divide the total Volume by the volume that each piranha needs
15.708/ 1.5 = 10.472 or ten pirahnas because we can't put a fraction of a piranha in the tank.
147 is not a perfect square. The reason 147 is not a perfect square is because, we know that 144 is a perfect square because you can divide it by 12. So that means that your square root would be inbetween 12 and 13. If you multiple 12•12 you get 144. And if you multiply 13•13 you get 169. So neither of those numbers are equal 147 so 147 is NOT a square but the closest square root is 12.

I'm going to say its 31668
