X=27
You have to divide 4x=108 and you get 27!
Answer:
1529.4 m^3
Step-by-step explanation:
We will use the formula V = 1/3*h*B for the volume of the pyramid, where V is volume, h is height, and B is are of the base.
First, since we know h and are looking for V, we need B. To find this, since it has a square base, we multiply b, the base length, by itself. 15.3m * 15.3m = 234.09m^2.
Next, we plug into the formula.
V = 1/3*19.6m*234.09m^2
And simplify:
V= 1/3 * 4,588.164m^3
V= 15.29.3879....
Last, round to the tenth
1529.4 m^3
We multiply 763 by 0.29 which is 221.27.
Then we subtract that from 763.
763-221.27=541.73
So you would have about 542 brushes if they were originally decrease but 29%.
I hope this helps!
