Answer:
60 math problems.
Step-by-step explanation:
30/2.5=12
12*5=60
Answer:
C
Step-by-step explanation:
First, we have to find the equation that will give the rabbit population as a function of time and the initial population.
The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,
To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.
You can now find the difference in the number of rabbits at year 3 for the different starting populations.
Answer:
![V=3141.59\ \text{feet}^3](https://tex.z-dn.net/?f=V%3D3141.59%5C%20%5Ctext%7Bfeet%7D%5E3)
Step-by-step explanation:
Given that,
The height of the pile, h = 25 feet
The radius of the pile, ![r=1.2\times 10^2\ ft](https://tex.z-dn.net/?f=r%3D1.2%5Ctimes%2010%5E2%5C%20ft)
We need to find the volume of the pile of cone. The formula for the volume of a cone is given by :
![V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{1}{3}\pi \times (1.2\times 10^2)\times 25\\\\V=3141.59\ \text{feet}^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h%5C%5C%5C%5CV%3D%5Cdfrac%7B1%7D%7B3%7D%5Cpi%20%5Ctimes%20%281.2%5Ctimes%2010%5E2%29%5Ctimes%2025%5C%5C%5C%5CV%3D3141.59%5C%20%5Ctext%7Bfeet%7D%5E3)
So, the required volume of the pile is
.
I think 5x represents 90 degrees.
5x = 90
x = 90/5
x = 18
