Answer:

There is really no answer to this because this is the furtherest you can go to simplify this expression. I can help solve it if you give me more information, or you tell me what the value of a and b is so I can solve it.

Thanks!

Use prime factorization to reduce the fraction 36/180
laila [671]

Answer:

Step-by-step explanation:

36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3

180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5

\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} =  \frac{1}{5}

Which of the following has a value of 84? <br> A. 512 <br> B. 4,096 <br> C. 32 <br> D. 83
andreev551 [17]
Answer is B. 4,096

I encountered this problem before. This is a trick question.
84 is not really the number 84. It is 8 raised to the 4th power.

So 8⁴ is equal to 4,096.

8 x 8 x 8 x 8 = 4,096

    8 x 8 =      64
  64 x 8 =    512
512 x 8 = 4,096

To win a trivia game, Nathan must score at least 75 points. Each correct answer is worth 2 1/2 points , and each incorrect answe
Dmitrij [34]

Answer:

He scored 79\frac{1}{2} points.

Step-by-step explanation:

Given:

Number of points for a correct answer = 2\frac{1}{2}

Number of points scored for an incorrect answer = -\frac{1}{4}

Therefore, for 35 correct answers, points scored = 35\times 2\frac{1}{2}=35\times \frac{5}{2}=\frac{175}{2}

Now, for 32 incorrect answers, points scored = 32\times -\frac{1}{4}=-\frac{32}{4}=-8

Therefore, net number of points scored by Nathan is:

\frac{175}{2}-8=\frac{175}{2}-\frac{16}{2}=\frac{175-16}{2}=\frac{159}{2}=79\frac{1}{2}

Therefore, Nathan scored 79\frac{1}{2} points.
