Answer: -rad7, +rad7
Explanation:
- Divide the equation by 6 (x^2-7=0)
- Add 7 (x^2=7)
- Square root x to find solutions (x=rad7)
- Dont forget the radical means that there are two solutions!
Answer:

Step-by-step explanation:
the volume of a cylinder is given by:

and the volume of a cone is given by:

since both have the same height and radius, we can solve each equation for
(because this quantity is the same in both figures) and then match the expressions we find:
from the cylinder's volume formula:

and from the cone's volume formula:

matching the two previous expressions:

we solve for the volume of a cone
:

substituting the value of the cylinder's volume 

Answer:
No
Step-by-step explanation:
First, You would multiply 3 and 6 because there are 3 classes in each of the six grades. The you would added that answer with 4 because we csnt forget about the Kindergarten classes. So, all of this is 3×6+4=22. then divide 1,000 by 22 and you get 45.45454545... so this cannot divided equally. ☺
5h + 2(11-h) = -5
5h +2*11 +2*(-h) = -5
5h +22 -2h = -5
3h + 22 = -5
3h = -5 -22
3h = -27
------
Therefore:
h=(-9), as 3 *(-9) = -27
A mixed number is (a whole number) plus (a fraction).
The smallest whole number is '1', so every mixed number is greater than '1'.
2/10 is less than '1'. Nothing you do to it can make it a mixed number.
It just doesn't have what it takes to be a mixed number.
