1. Mark charges $10 an hour to babysit with an additional flat fee of $20 for each babysitting job. He wants to purchase a new game system that will cost him $123.50. Write an inequality to show the least number of complete hours he needs to babysit if he has one job scheduled.

A. Solve the inequality that you created.

B. Mark is considering changing his rate to $ 15.00 an hour with no flat fee. What effect would this change have on the hours that Mark needs to work to buy the gaming system?

C. What conclusions can you draw about Jamie charging the flat fee and not charging the flat fee?

Please help!!

Answers

Answer:

Step-by-step explanation:

A.123.50≤20+10(x)

103.50≤10x

10.35 hours at least to equal the 123.50.

10.35 hours *10 an hour is 103.50+20 flat fee=123.50

B. 123.50≤15(x)

8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60

C. He will work less hours if he charges more and does not charge the flat fee.

Answer: let x = amount of hours worked.

A. 10x + 20 >or= 123.50 --- 10x >or= 143.50 --- x >or= 14.35 hours.

B. 15x >or= 143.50 --- x >or= 9.57 hours.

C. Jamie would only have to work 9.57 hours to get his gaming system if he charged 15$ with no flat fee as opposed to 14.35 hours of work with the flat fee.

A carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.

There are three different sized screws shown. The screws are marked two and a half inches, two inches, and one and a half inches.

What is the ratio of 1.5-inch screws to 2.5-inch screws, written in three different ways? Do not reduce.

Answers

Answer:

2:10

Step-by-step explanation:

The Ratio of 1.5-inch screws to 2.5-inch screws = 36/12 = 12/4 = 6/2 = 3/1

What are Ratios?

A ratio is a relationship between two things when it is expressed in numbers or amounts.

Given that a carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.

According to question we get,

Ratio of 1.5-inch screws to 2.5-inch screws = 36/12

Equivalent ratios = 12/4, 6/2, 3/1

Hence, The Ratio of 1.5-inch screws to 2.5-inch screws = 36/12 = 12/4 = 6/2 = 3/1

Answer: output = -1n + 7 or  -n + 7

n can represent any number.

Step-by-step explanation:  using the slope-intercept form y = mx + b

y is the output. x is any input.  m is the slope.  b is the constant.

Calculate the slope:  rise ÷ run  

You see all the inputs in the chart are going up by 1. This is the run +1

You see all the outputs going down by 1.   This is the rise:  -1

So the slope, m,  is rise / run . -1/1 =  -1

To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.

y = mx + b  becomes   6 = -1(1) + b . Solve for b

6 = -1 + b

6 +1 = -1 +1 + b

7 = b

Now set up the equation that answers the question using the calculated values of m and b.

y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:

Output = -1n + 7

or -n + 7  as 1 is usually implied.

-n+7 this is the answer sis

TIMED PLEASE HURRY. Read the excerpt from William Sewards The Building of the Erie Canal.The public debt for canals in 1825 amounted to seven and a half million dollarsall of which, it must be recorded to the honor of the State and the country, had been borrowed of American capitalistsand the annual interest thereon, to three hundred seventy-six thousand dollars. The Governor estimated that the tolls for the year would exceed three hundred ten thousand dollars; that the duties on salt would amount to one hundred thousand dollars, and that these, with the other income of the canal fund, would produce a revenue exceeding, by three hundred thousand dollars, the interest on the canal debt. He stated also that ten thousand boats had passed the junction of the canals near tide-water during the previous season. Remarking that the creative power of internal improvement was manifested in the flourishing villages which had sprung up or been extended; in the increase of towns; and, above all, in the prosperity of the city of New York. And noticing the fact that three thousand buildings had been erected in that city during the preceding year, Clinton predicted that in fifteen years its population would be doubled, and that in thirty years that metropolis would be the third city in the civilized world, and the second, if not the first, in commerce.How were large public works such as canals paid for in the early 1800s?through public fundingby wealthy individual investorsthrough private banksby trust shareholders Compute the variances in dollar amount and in percentage.
