c is the correct one

Answer:

Probably C

Step-by-step explanation:

Repeating Decimal: a decimal where a number or a pattern of numbers repeats forever

For example, 0.2222... or 0.671671....  (The "..." means that it repeats like that forever)

A. 3/7=  0.142857142857142857... (6 repeating digits)  This is a repeating decimal because the last six digits continue forever

B. 3/4=0.75. This number is not a repeating decimal because a repeating decimal goes on forever, while this only has two decimal places.

C. 1/9= 0.11111... This is a repeating decimal because it goes on forever and has a pattern (all are 1s)

D. 5/11=0.454545... This is also a repeating decimal because the last two digits repeat forever.

There is probably something wrong with the question (or your unit) because three of these numbers are, in fact, repeating decimals. If I were you, I would ask your teacher (it gets you respect from the teacher=more chance that they'll be lenient with you)

But if you really don't want to, I would go with "C" because it only has one repeating decimal place, and your curriculum probably says that a repeating decimal is only one digit.

Good Luck! :)

You earn $56 walking your neighbor's dog for 8 hours. Your friend earns $36 painting your neighbor's fence for 4 hours.
What is your pay rate? And What is your friend's pay rate?

Answers

Answer:

Your pay rate is:  

$ 7  per hour

Your friend's pay rate is  :

$ 9  per hour

Explanation:

So if it takes you  8  hours to make  $ 56 , you can just divide the total money earned by the time.  So it would be  56 ÷ 8  which is  7 .

And if takes your friend  4  hours to make  $ 36 , you can divide like we just did . So it would be  36 ÷ 4  which is  9 .

So you make  $ 7  per hour and your friend makes  $ 9 per hour.

you would divide 56 by 8 to get 7. which is your pay rate. Then you would divide 36 by 4 to get 9. which is your friends pay rate.

Everything else he did was correct! When got down to the bottom he made a mistake.

Because there was a zero, grant should have token away from the 4 in which it would become a 3 and given to the 0 so it would become a 1. Due to the fact that he did not do this he got it wrong.

29.25

Step-by-step explanation:

This is a simple function table we are working with, so we see that 2 (pounds) would cost around $4.50. So Next we look at 4 would equal $9. By doing this I divide 9 by 4 to get the answer of 2.25. This is are new function table rule of C=P x 2.25. Now that we have this we know that 13 is are P (pounds) and we are looking for are C (cost) After we input 13 into are function rule. We get the answer of $29.25.

Answer:  well 14 pounds cost $31.50

so that means 13 pounds cost $29.50

Mary and Julie both have a goal of raising $1000 for
charity. Mary raises $12 every 4 days. Julie raises $19
every 6 days.
Will Mary or Julie reach her goal first? Explain.

This is the sample response… Mary would have a rise of 12 and a run of 4, making her slope, or rate of change, $3 a day. Julie would have a rise of 19 and a slope of 6, making her slope, or rate of change, $3.17 a day. Since Julie is raising money at a faster rate, she would get to the goal of $1000 first.

This is the info that you should include in your response… Mary has a rise of 12 and a run of 4. Mary has a slope of 3. Julie has a rise of 19 and a run of 6. Julie has a slope of 19/6 or 3 and 1/6. Julie will reach her goal first, as she has the greater slope.

Use this information at your advantage.

h = 20c + 15

c = 15h + 20
