Solution :
First Jerome reach 20 floors up from the elevator.
Then, Jerome took the stairwell down 2 floors for a morning meeting.
So, currently he is on 20 - 2 = 18 floor.
Now, it is given that he took the elevator down 8 floors for lunch in the cafeteria.
Current position is 18 - 8 = 10 floor.
Finally, he walk 4 floors upstairs for after noon meeting.
Final position is 10 + 4 = 14 floor.
Therefore, in the end he is in 14 floor for the afternoon meeting.
Answer:
![V=40\ in^3](https://tex.z-dn.net/?f=V%3D40%5C%20in%5E3)
Step-by-step explanation:
The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula
![V=\frac{1}{3}Bh](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7DBh)
where
B is the area of the triangular face
h is the height of the pyramid
we have
![B=12\ in^2\\h=10\ in](https://tex.z-dn.net/?f=B%3D12%5C%20in%5E2%5C%5Ch%3D10%5C%20in)
substitute the given values
![V=\frac{1}{3}(12)(10)=40\ in^3](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B1%7D%7B3%7D%2812%29%2810%29%3D40%5C%20in%5E3)
If we know the ration is 4:7, we know that both 4 an 7 need to be multiplied by the same exact number to equal 350. That leads us to set up the following equation:
4x + 7x = 350
We combine like terms to get:
11x = 350
We divide by 11 on both sides to get:
x= 31.82
7x represents the number of girl so :
7 * 31.82 = 222.72
Because the question says to round down, the answer is 222
Answer: I think it's 272.4
