Answer:

D 7x( x^2y) ^1/3

Step-by-step explanation:

5x (x^2y)^1/3 +2 (x^5y)^1/3

We can simplify the second term

2 (x^5y)^1/3 = 2 (x^3 * x^2y) ^1/3

We know that (a*b) ^c = a^c * b^c

2 (x^3 * x^2y) ^1/3 = 2 (x^3 )^1/3*( x^2y) ^1/3

2*x*( x^2y) ^1/3

Replacing this into the original equation

5x (x^2y)^1/3 +2x( x^2y) ^1/3

The term inside the cube root is the same, so we can add the terms on the outside

(5x+2x) 2x( x^2y) ^1/3

(7x)( x^2y) ^1/3

Amount $100,000

sergey [27]

Answer:

1) Repaid for the loan = $239,511.60

2) Percentage = 58.2%

3) Average amount = $387.53

Step-by-step explanation:

Given :

Amount $100,000

Rate 7%

Payments 360 - $665.31

Total interest $139,511.60

To find :

1) How much will be repaid for this loan?

Repaid for the loan = Amount - Total interest

Repaid for the loan = 100,000 + 139,511.60

Repaid for the loan = $239,511.60

2) What percentage will be repaid for this loan?

$\text{Percentage}=\frac{\text{Total interest}}{\text{Repaid loan}}\times100$

$\text{Percentage}=\frac{139511.60}{239511.60}\times100$

$\text{Percentage}=0.582\times100$

$\text{Percentage}=58.2\%$

3) What will be the average amount per payment for interest?

$\text{Average amount}=\frac{\text{Total interest}}{\text{Payments}}$

$\text{Average amount}=\frac{\text{139511.60}}{\text{360}}$

$\text{Average amount}=387.53$

Bob bought 3 packs of model cars he gave 4 cars to ann Bob has 11 cars left how many model cars were in each pack

Harrizon [31]

First add 11 and 4 because you need to know how many he had in total 11+4=15 then divide 15 by 3 and then you have you answer 15/3=5.
There are 5 model cars in each pack.

Anyone know how to do area or volume? Any help will do! thanks

exis [7]

Answer:

Volume: x(x+6)(x+2) Area: $x^{2}$ + 8x +12

Step-by-step explanation:

Volume Explanation:

To find the volume of a 3d figure, we must multiply the length, width, and the height. Therefore we multiply (x)(x+6)(x+2)= $x^{3}$ + 8 $x^{2}$ + 12x. Simplify this equation and we will get x(x+6)(x+2) for the formula to find the volume of the 3D figure.

Area:

To find the area of a 2D figure, we must multiply length x height. Therefore, we multiply the equations (x+6)(x+2)= $x^{2} + 2x + 6x +12$ to get a final answer of $x^{2} +8x +12$ . This will be the formula when you find the area of the 2D figure in question.
