1. 72 to 50 points
50/72 = 69%
100-69= 31% decrease
2. 14 to 40 books
14 / 40 = 35%
100-35= 65% increase
3. 10 plus 30% increase
10 * 0.3 = 13

➷ First find the volume of the rectangular prism:
2 x 4 x 8 = 64
Now you need to cube root it, this would be because all lengths of a cube are equal:
![\sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D%20%3D%204)
The side length would be 4 inches.

Answer:
i think the answer is $3.45
Step-by-step explanation:
just had to divide the two numbers
Answer:
The general relation about a geoemtric sequence is

For the first sequence, we have


Which is a system of equations. We can isolate a variable in the first equation to replace that expression into the second equation.


![r^{2}=\frac{147}{3}\\ r=\sqrt[2]{49}\\r=7](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D%5Cfrac%7B147%7D%7B3%7D%5C%5C%20%20r%3D%5Csqrt%5B2%5D%7B49%7D%5C%5Cr%3D7)
Now, we replace this value to find the other one

Therefore, the explicit rule function is

Now, we use the same process for the second sequence.

The second equation is

Now, we solve the following expression

We solve for 

Then

Therefore, the function that models the second sequence is

Notice that
is the dependent variable and
is the independent variable.
