Steven earns extra money babysitting. He charges $31.25 for 5 hours and $50 for 8 hours explain why the relationship between how much Steven charges and time is a proportional relationship.

Answers

Answer 1

Answer:

The relationship between the amount of money Steven charges and the time he spends babysitting is proportional because the hourly rate remains constant.

What is the proportional relationship?

A proportional relationship between two variables means that the ratio of the two variables is constant. In other words, if the independent variable (time in this case) increases, the dependent variable (the amount of money Steven charges) will increase proportionally.

In this situation, we can see that the relationship between the amount of money Steven charges and the time he spends babysitting is proportional because the rate of change between the two variables is constant.

For example, Steven charges $31.25 for 5 hours, so his hourly rate is $31.25/5 = $6.25/hour.

And he charges $50 for 8 hours, so his hourly rate is $50/8 = $6.25/hour.

Since the hourly rate remains constant, the relationship between the amount of money Steven charges and the time he spends babysitting is proportional.

Which answer is the most reasonable estimation? Mike is driving a total of 100 miles. He drove 23 miles before stopping at a gas station. Then he drove 58 more miles before stopping for lunch. About how much farther does Mike have to drive? A. about 20 miles B. about 80 miles C. about 10 miles D. about 70 miles

Answers

the answer is A because if you subtract 100-23-58 you get 19 then you simplify it

23 rounds to 20.
58 rounds to 60.

You then take your rounded numbers, 60 + 20 = 80. So, Mike has driven ABOUT 80 miles so far.

Now you take his estimated distance & subtract it from the 100. Your answer is 20. So, your answer is A) 20 miles.

To check your work, you could add 23 + 58 = 81. You then subtract 100 - 81 = 19. 19 rounds to 20, which is your answer.

Then subtract -500000 = 5794.62498636

Step-by-step explanation:

Why, because the first year is proved 5000 x 0.08 = 400

= 400 year 1 but cna keep only if stays in investment for 10 years

400 x 10 = 4000 interest on investment

5000+ 4000 = $9,000.00 SI

+ 1,794.62 Interest on interest if applies (this is called CI) and makes $10794.62

What times 10 equals 400

Answers

The answer is 40

-------
400

So this is your equation to figure it out: n*10 = 400
To get rid of the times 10, you need to divide both sides by 10.
Now you have n*10/10 = 400/10
The 10's on the left cancel each other out, so now you have n=400/10
400 divided by 10 is 40
ANSWER: 40
