Answer:
-8,6
Step-by-step explanation:
from what i can tell this is a 1D problem. |E-G|=7, and E=-1, so -1-G=+-7. G=-8 or 6
18.90? I believe would be the answer . Let's see if someone else responds
Answer:
Step-by-step explanation:
Solution,
The perimeter of a triangle=Sum of all sides
![16.2in+10.04in+12.2in\\=38.44inches](https://tex.z-dn.net/?f=16.2in%2B10.04in%2B12.2in%5C%5C%3D38.44inches)
Hope it will help you a lot.
I think that the answer is 120 cubes
The volume of a box with dimensions x by x by x is
![x^{3}](https://tex.z-dn.net/?f=%20x%5E%7B3%7D%20)
.
So if we are given the volume V of a cube-shaped box, the side length of thit is
![\sqrt[3]{V}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7BV%7D%20)
.
So we calculate the cubic roots of the volumes we have, and we add their heights.
To calculate the cubic root of 729, we can factorize it, and group the perfect cubes together, as follows:
![\frac{729}{3}= \frac{600}{3} + \frac{120}{3} + \frac{9}{3}=200+40+3=243](https://tex.z-dn.net/?f=%20%5Cfrac%7B729%7D%7B3%7D%3D%20%5Cfrac%7B600%7D%7B3%7D%20%2B%20%5Cfrac%7B120%7D%7B3%7D%20%2B%20%5Cfrac%7B9%7D%7B3%7D%3D200%2B40%2B3%3D243%20%20)
![\frac{243}{3}= \frac{240}{3}+ \frac{3}{3}=80+1=81](https://tex.z-dn.net/?f=%20%5Cfrac%7B243%7D%7B3%7D%3D%20%5Cfrac%7B240%7D%7B3%7D%2B%20%5Cfrac%7B3%7D%7B3%7D%3D80%2B1%3D81%20%20%20)
, which we recognize as
![3^{4}](https://tex.z-dn.net/?f=%203%5E%7B4%7D%20)
so
![729=3*3* 3^{4}= 3^{6}= ( 3^{2} )^{3}= 9^{3}](https://tex.z-dn.net/?f=729%3D3%2A3%2A%203%5E%7B4%7D%3D%203%5E%7B6%7D%3D%20%28%203%5E%7B2%7D%20%29%5E%7B3%7D%3D%209%5E%7B3%7D%20%20)
similarly 1,331 can be found to be
![11^{3}](https://tex.z-dn.net/?f=11%5E%7B3%7D)
.
Thus we have 2 boxes with side length equal to 11 m and one with side length equal to 9 m.
Answer: h= 11+11+9 = 31 (meters)
