What? I don't understand.
-1^3 - -1^2 +1= -1. ...........
Answer:
12 liters
Step-by-step explanation:
Let the capacity sum of the 5 containers be X
13 = X / 5
X = 65 liters
Average capacity of the six = ( 65 + 7 )/ 6 liters
= 72/6 liters
= 12 liters
<u>Answer:</u>
3/5
<u>Step-by-step explanation:</u>
We are to find the similarity ratio of a cube with volume
to a cube with volume
.
We know the formula for the ratio of two cubes:
where
is the similarity ratio of the two cubes.
Substituting the given values in the formula to find
:
![k^3 = \frac {729} {3375}](https://tex.z-dn.net/?f=%20k%5E3%20%3D%20%5Cfrac%20%7B729%7D%20%7B3375%7D%20)
![k^3 = \frac {27} {125}](https://tex.z-dn.net/?f=%20k%5E3%20%3D%20%5Cfrac%20%7B27%7D%20%7B125%7D%20)
![k^3 = (\frac {27} {125})^3](https://tex.z-dn.net/?f=k%5E3%20%3D%20%28%5Cfrac%20%7B27%7D%20%7B125%7D%29%5E3)
![k=\frac{3}{5}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B3%7D%7B5%7D)
Therefore, the similarity ratio of the two cubes is 3/5.
