Answer:
21. 
22. 87.92
Step-by-step explanation:
21. The quotient means division is going to happen between -s and 15. And then take the square root of that.
22. The equation for the volume of a cylinder is this:
The question gives you values for r, and h, so just substitute those values into the equation.
Here is the work:
They told us to use 3.14 for pi, so i will substitute pi with 3.14
Answer:
3a=6-3
Step-by-step explanation:
if you have the equation 3a + 3 = 6, you have to move 3 to the other side of the equation to isolate it. To do this, you subtract 3 from both sides giving you 3a=6-3

Answer:
1. 10 x 12 = 120 2. 4 (48/12)
we have the number
![6-\sqrt[]{-40}](https://tex.z-dn.net/?f=6-%5Csqrt%5B%5D%7B-40%7D)
Remember that
i^2=-1
so
substitute
![6-\sqrt[]{(i^2)40}](https://tex.z-dn.net/?f=6-%5Csqrt%5B%5D%7B%28i%5E2%2940%7D)
![6-2i\sqrt[]{10}](https://tex.z-dn.net/?f=6-2i%5Csqrt%5B%5D%7B10%7D)
therefore
the real part is 6
the imaginary part is -2√10
Answer:
0.923
