<u>Answer:</u>

\frac{81m^2n^5}{8}

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

\frac { (3 m^ {-1} n^2 )^ 4} {( 2m ^ {-2} n ) ^3}

Expanding the terms in both the numerator and the denominator by multiplying them with their whole powers to get:

= \frac{3^4m^{-4}n^8}{2^3m^{-6}n^3}

=\frac{81m^{(-4+6)}n^{(8-3)}}{8}

Cancelling all the like terms to get:

=\frac{81m^2n^5}{8}

Therefore, option B is the correct answer.

barxatty [35]

Answer:

1080

Step-by-step explanation:

Firstly, if he is paying 50 per month, we need to know the number of months it would take him to finish paying the money. Hence that would be 800/50 = 16 months

Now we know there is a surcharge of 17.5 for each month he owes a balance. The total balance he is to pay is thus 16 * 17.5 = 280

The total cost of the jacket is thus 800 + 280 = 1080

I need with #10, please?
777dan777 [17]

Answer:

h=7ft

Step-by-step explanation:

sinФ=opposite/hypotenuse

sin45°=5/h

0.71=5/h

multiply via by h

0.71h=(5/h)h

h cancel h it remains 5

0.71h=5

divide through by 0.71

0.71h/0.71=5/0.71

h=7.04ft

h=7ft approximately

Answer: x=−3

Step-by-step explanation: Let's solve your equation step-by-step.

2

3

(3x+9)=−2(2x+6)

Step 1: Simplify both sides of the equation.

3

(3x+9)=−2(2x+6)

(

)(3x)+(

2

3

)(9)=(−2)(2x)+(−2)(6)(Distribute)

2x+6=−4x+−12

2x+6=−4x−12

Step 2: Add 4x to both sides.

2x+6+4x=−4x−12+4x

6x+6=−12

Step 3: Subtract 6 from both sides.

6x+6−6=−12−6

6x=−18

Step 4: Divide both sides by 6.

6x

6

=

−18
