Answer:
The first one is 45 hours
The second is 1361
Answer:
1001.
Step-by-step explanation:
1. if B=11*13; h=7, then
2. V=11*13*7=1001.
The volume of a sphere is given by the equation
![V= \frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B4%7D%7B3%7D%20%20%5Cpi%20r%5E3)
, where r is the radius.
We are given the diameter of the sphere, but recall that the diameter is twice the radius:
![d=2r](https://tex.z-dn.net/?f=d%3D2r)
. So the radius is half of the diameter:
![r= \frac{1}{2}d](https://tex.z-dn.net/?f=r%3D%20%5Cfrac%7B1%7D%7B2%7Dd)
.
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for <span>π.</span>
Answer:
A
Step-by-step explanation:
It IS a function because it passes the vertical line test.
If you drew vertical lines through any part of the graph, it would only touch one point, showing that it is a function.
Answer:
It is the distance that -5 is from 0 on the number line
