Leah would like to earn at least $120 per month. She babysits for $5 an hour and works at an ice cream shop for $10 per hour. Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop.

Answers

This question is incomplete

Complete Question

Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y

represent the number of hours Leah works at the ice cream shop.

Answer:

The inequalities to solve this question is given as:

x + y ≤ 20

5x + 10y ≥ 120

Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

Step-by-step explanation:

Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.

Hence:

x + y ≤ 20 ...... Equation 1

Leah would like to earn at least $120 per month.

She babysits for $5 an hour and works at an ice cream shop for $10 per hour.

Hence, out Equation is given as:

x × $5 + y × $10 = $120

5x + 10y ≥ 120..... Equation 2

The inequalities to solve this question is given as:

x + y ≤ 20

5x + 10y ≥ 120

To find x and y:

x + y = 20

x = 20 - y

5x + 10y = 120

Substitute: 20 - y for x

5(20 - y) + 10y = 120

100 - 5y + 10y = 120

Collect like terms

- 5y + 10y = 120 - 100

5y = 20

y = 20/5

y = 4 hours

Note:

x = 20 - y

x = 20 - 4

x = 16 hours

Hence:

Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

L.B. Johnson Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and the audience. Altogether, they sold 486 items that totaled $2673. If the chess club sold each item at the same price, calculate the price of each item. Do not include units ($) in your answer.

Answers

Answer:

Price of each item = 5.50

Step-by-step explanation:

Total items sold = 486

Total price of items sold = $2,673

If the chess club sold each item at the same price,

Price of each item = Total price of items sold / Total items sold

= $2,673 / 486

= $5.50

Price of each item = $5.50

Excluding the units ($) in the answer

Price of each item = 5.50

Simplifying 4y + -70 = 12y + 2

Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y

Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as F ( x )

Now , the value of F ( x ) is

F ( x ) = 9x be equation (1)

Now , let the inverse of the function be represented as F' ( x )

where , the values of y are interchanged with x

So , the equation is

y = 9x

when x in interchanged ,

x = 9y

On solving for y , we get

Divide by 9 on both sides , we get

y = x / 9

So , the inverse of the function is F' ( x ) = x/9

Hence , the inverse of the function is F' ( x ) = x/9

Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = −8t + 92.

Answers

Here is the complete question I was able to find:

Tanya is printing a report. There are 92 sheets of paper in the printer, and the number of sheets of paper p left after t minutes of printing is given by the function p(t) = -8t + 92.

How many minutes would it take the printer to use all 92 sheets of paper?

Answer:

The printer needs 11.5 minutes to use all 92 sheets of paper.

Step-by-step explanation:

Given the function

p(t) = −8t + 92

We need to determine how many minutes would it take the printer to use all 92 sheets of paper?

We know that putting p(t) = 0 means we will be able to determine the time when all the 92 sheets of paper will have been printed.

Because, putting p(t)=0 means there won't be any sheet left.

Thus, plug in p(t) = 0 in the function and calculate the time 't'

p(t) = −8t + 92

0 = −8t + 92

adding 8t to both sides

8t = −8t + 92 + 8t

8t = 92

dividing both sides by 8

8t/8 = 92/8

t = 11.5 minutes.

Thus, the printer needs 11.5 minutes to use all 92 sheets of paper.

PLEASE AWNSER FAST!!!!!!!!The Book of DragonsChapter III The Deliverers of Their Country, an excerptBy E. NesbitIt all began with Effie's getting something in her eye. It hurt very much indeed, and it felt something like a red-hot sparkonly it seemed to have legs as well, and wings like a fly. Effie rubbed and criednot real crying, but the kind your eye does all by itself without your being miserable inside your mindand then she went to her father to have the thing in her eye taken out. Effie's father was a doctor, so of course he knew how to take things out of eyes.When he had gotten the thing out, he said: "This is very curious." Effie had often got things in her eye before, and her father had always seemed to think it was naturalrather tiresome and naughty perhaps, but still natural. He had never before thought it curious.Effie stood holding her handkerchief to her eye, and said: "I don't believe it's out." People always say this when they have had something in their eyes."Oh, yesit's out," said the doctor. "Here it is, on the brush. This is very interesting."Effie had never heard her father say that about anything that she had any share in. She said: "What?"The doctor carried the brush very carefully across the room, and held the point of it under his microscopethen he twisted the brass screws of the microscope, and looked through the top with one eye."Dear me," he said. "Dear, dear me! Four well-developed limbs; a long caudal appendage; five toes, unequal in lengths, almost like one of the Lacertidae, yet there are traces of wings." The creature under his eye wriggled a little in the castor oil, and he went on: "Yes; a bat-like wing. A new specimen, undoubtedly. Effie, run round to the professor and ask him to be kind enough to step in for a few minutes.""You might give me sixpence, Daddy," said Effie, "because I did bring you the new specimen. I took great care of it inside my eye, and my eye does hurt."The doctor was so pleased with the new specimen that he gave Effie a shilling, and presently the professor stepped round. He stayed to lunch, and he and the doctor quarreled very happily all the afternoon about the name and the family of the thing that had come out of Effie's eye.But at teatime another thing happened. Effie's brother Harry fished something out of his tea, which he thought at first was an earwig. He was just getting ready to drop it on the floor, and end its life in the usual way, when it shook itself in the spoonspread two wet wings, and flopped onto the tablecloth. There it sat, stroking itself with its feet and stretching its wings, and Harry said: "Why, it's a tiny newt!"The professor leaned forward before the doctor could say a word. "I'll give you half a crown for it, Harry, my lad," he said, speaking very fast; and then he picked it up carefully on his handkerchief."It is a new specimen," he said, "and finer than yours, Doctor."It was a tiny lizard, about half an inch longwith scales and wings.So now the doctor and the professor each had a specimen, and they were both very pleased. But before long these specimens began to seem less valuable. For the next morning, when the knife-boy was cleaning the doctor's boots, he suddenly dropped the brushes and the boot and the blacking, and screamed out that he was burnt.And from inside the boot came crawling a lizard as big as a kitten, with large, shiny wings."Why," said Effie, "I know what it is. It is a dragon like the one St. George killed."And Effie was right. That afternoon Towser was bitten in the garden by a dragon about the size of a rabbit, which he had tried to chase, and the next morning all the papers were full of the wonderful "winged lizards" that were appearing all over the country. The papers would not call them dragons, because, of course, no one believes in dragons nowadaysand at any rate the papers were not going to be so silly as to believe in fairy stories. At first there were only a few, but in a week or two the country was simply running alive with dragons of all sizes, and in the air you could sometimes see them as thick as a swarm of bees. They all looked alike except as to size. They were green with scales, and they had four legs and a long tail and great wings like bats' wings, only the wings were a pale, half-transparent yellow, like the gear-boxes on bicycles.Based on the rising action in the bolded paragraphs, what do we know about Daddy?
