Step-by-step Answer:

To answer this question, we can simplify each expression and then substitute n.  

If you use a calculator, you can just plug-in n=2 to see which one is the greatest.

A. n^5*n^2/n^4 = n^(5+2-4) = n^3

B. n^2*n^3/n = n^(2+3-1) = n^4

C. (n^2)^3/n = n^(2*3-1) = n^5

D (n^5)^2/n^4 = n^(5*2-4) = n^6

As long as n>1, the higher power n has, the larger is the number.

Therefore (n^5)^2/n^4 = n^(5*2-4) = n^6 is the winner!

If m∠NOP = 24° and m∠NOQ = 110°, what is m∠POQ?
monitta

Correct answer for the above question is - option B. 86°

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

Given:

∠NOP = 24°

∠NOQ = 110°

∠NOP and ∠POQ are adjacent angles

To Find:

∠POQ = ?

Solution:

Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )

∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

<u>∠POQ = 86°</u>

Angle POQ is  86°

Thus we can conclude option B as correct answer.

Solve this system of equations. <br><br> 12x − 18y = 27 <br> 4x − 6y = 10
kifflom [539]

Answer:

no solution

Step-by-step explanation:

12x − 18y = 27  

4x − 6y = 10

Multiply the second equation by -3 so we can eliminate x

-3(4x − 6y) = 10*-3

-12x +18y = -30

Add the first equation to this new equation

12x − 18y = 27

-12x +18y = -30

------------------------

0 = -3

This is not a true equation, so there is no solution

kozerog [31]

Step-by-step explanation:

profit%=

\frac{selling \: price - cost \: price}{cost \: price}  \times 100\%

\frac{4950 \: naira - 3600 \: naira + 150 \: naira}{3750 \: naira}  \times 100\%

\frac{4950 - 3750}{3750}  \times 100\%

\frac{1200}{3750}  \times 100\%

=36%
