Answers

Answer 1

Answer:

we know that

To convert the decimal as fraction in this problem, multiply and divide by one hundred

$0.07=0.07*(100)/(100)=(0.07*100)/(100)=(7)/(100)$

therefore

the answer Part a) is

the decimal as fraction is equal to $(7)/(100)$

Part b)

we know that

$1$ dollar is equal to $100$ cents

$1$ cent is equal to $0.01$ dollars

the tax is equal to $0.07$ dollars

by proportion

$(100)/(1) (cents)/(dollar)=(x)/(0.07) (cents)/(dollars)\n \nx=100*0.7\n \nx=7\ cents$

the tax is equal to $7$ cents

therefore

the answer part b) is

There are $7$ cents of tax in each dollar

8 1/2 by 11 inches dilated to 1 7/10 inches by 2 1/5 inches. what is the scale factor

Answers

8 1/2 by 11.

Area1 = 8 1/2 × 11

Area1 = 17 / 2 × 11 = 187/2

17/10 by    2 1/5

Area2 = 17/10 ×   11/5

Area2 = 17 / 10 × 11/5 = 187/50

Scale factor = Area1 / Area2

   = 187/2 ÷ 187/50

   = 187/2 × 50/187

   = 25

Scale factor = 25

You and your friend get the same magazine. You spend $15 for twelve issues. Your friend pays $1.50 per issue but gets the first two issues free. How many issues will your friend get if he also spends $15?

Answers

The friend will get 12 issues for $15.

What is a Ratio?

A ratio indicates the number of times one number contains another.

Given that, the friend pays $1.50 per issue:

$1.5 = 1 issues

$1 = 1/1.5 issues

$15 = (1/1.5) × 15 issues

$15 = 10

Since the friend gets the first two issues free, he will get 10 + 2 =12 issues.

Hence, the friend will get 12 issues for $15.

he will get 12 issues too. Since he spent 15 dollars in total you would divide that by 1.50 to see how many he actually purchased and it comes out to 10 meaning that he got 10 issues with the money. Now he got two free issues so you would add them to the ones he purchased, so 10 + 2 which would equal 12. So in total he got 12 issues. I hope that helps and wasn't confusing.
