It is four. So two and two you add them together to be four. Good job. Your learning :)
Total # of people in English 102 is 122+164, or 286.
Since the number of males is 122, the unsimplified fraction is 122/286. In lowest terms, it would be 61/143 (divide the original fraction by 2).
Answer:
Option A
. 1708 bags
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the volume of the silo
The volume of the silo is equal to the volume of a cylinder plus the volume of a cone
so
![V=\pi r^{2}h_1+\frac{1}{3}\pi r^{2}h_2](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E%7B2%7Dh_1%2B%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E%7B2%7Dh_2)
we have
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
---> the radius is half the diameter
![h_1=16\ ft](https://tex.z-dn.net/?f=h_1%3D16%5C%20ft)
![h_2=12\ ft](https://tex.z-dn.net/?f=h_2%3D12%5C%20ft)
substitute
![V=(3.14)(8)^{2}(16)+\frac{1}{3}(3.14)(8)^{2}(12)](https://tex.z-dn.net/?f=V%3D%283.14%29%288%29%5E%7B2%7D%2816%29%2B%5Cfrac%7B1%7D%7B3%7D%283.14%29%288%29%5E%7B2%7D%2812%29)
![V=3,215.36+803.84=4,019.2\ ft^3](https://tex.z-dn.net/?f=V%3D3%2C215.36%2B803.84%3D4%2C019.2%5C%20ft%5E3)
Remember that
The silo is approximately 85% full
so
The volume of grain in the silo is
![0.85(4,019.2)=3,416.32\ ft^3](https://tex.z-dn.net/?f=0.85%284%2C019.2%29%3D3%2C416.32%5C%20ft%5E3)
step 2
Find the number of bags of grain
Divide the volume of grain in the silo by the volume of one sack
![3,416.32/2=1,708\ bags](https://tex.z-dn.net/?f=3%2C416.32%2F2%3D1%2C708%5C%20bags)
Looks like the answer might be around 20 i think
-1 because y-intercept is where y meets zero, therefore the y intercept of this graph would be -1<3
