Write 5^8 as a quotient of two exponential terms with the same base in four different ways. Use only positive exponents.

Answers

The correct answer for the question that is being presented above is this one: 

5^8 can be represented into two exponential terms as quotients.

5^8
= 5^12 / 5^4
= 5^9 / 5
= 5^10 / 5^2
= 5^15 / 5^ 7

If a cd player costs 49.95 what will your total be if you have to pay a 5% tax

Answers

To figure out the tax in any cost, you simply take the original cost, and multiply it by the tax which is written as 0.05, since it's in percent. once you get your answer, take the original cost and add on to the product you calculated before. ex 0.05 * 49.95 = 2.4975, now add the original price to the product: 2.4975 + 49.95 = 52.4475. Now just take your final answer and round it the proper decimal place which is to the hundredths place: $52.45. Therefore your final price is $52.45.

Hope that helps :)

There are 12 girls and 16 boys in javier's math class.There are 26 girls and 14 boys in javier's choir class.Is the ratio of girls to boys in the two classes equivalent? Explain

Answers

Answer:

Not equivalent

Step-by-step explanation:

A fraction is a part of whole .

Two fractions are said to be equivalent if their lowest forms are same .'A fraction (a)/(b) is said to be in lowest form if HCF(a,b)=1.

Given :

Number of girls = 12

Number of boys = 16

So, fraction = (Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)

 =(12)/(16)=(2* 2* 3)/(2* 2* 2* 2)=(3)/(4)

Number of girls = 26

Number of boys = 14

So, fraction = (Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)=(26)/(14)=(2* 13)/(2* 7)=(13)/(7)

As (3)/(4)\neq (13)/(7) , these fractions are not equivalent .

These ratios are not equivalent because if you calculate it, they do not start from the same simplified ratio. 12/16 is 3/4 and  26/14 is 13/7 and those two ratios are not equivalent. I hope this helped you

Lizzy bought 4 bags of apples at the store. Her mom gave her 8 more apples. Now Lizzy has 36 apples. How many apples were in each bag?

Answers

36 - 8 = 28
Lizzy bought a total of 18 apples from the store.
28/4=7
There are 7 apples in each bag.
4b+8=36
Subtract 8 from both sides
4b=28
Divide by 4 on both sides to get b by itself
b=7

7 apples were in each bag
