Answers

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! :)

1. Jane, Fay, and Henry had a total of $90. After Jane gave $12 to Henry and Fay gave $2 to Jane, all three of them had the same amount of money. How much money did each of them have in the beginning?
Jane has $__
Fay has $__
Henry has $__

2. The sum of three consecutive numbers is 723. Find the numbers.

The answer that is worth the Brainliest has all the answers to my questions, and is correct.

Answers

Answer:

1. J=20, f= 28, H=42

2. 240 + 241 + 242 = 723

Step-by-step explanation:

J= 30- 12= 18+2= 20

F= 30-2=28

H=30+12=42

240 + 241 + 242 = 723

1. Jane has $40 to begin with
Fay has $32 to begin with
Henry has $18 to begin with

They all end with the same amount which must be 30.

40-12=28.- Jane 18+12=30- Henry
32-2=30-Fay. 28+2=30

2. 240+241+242= 723

What is the slope of the line?

Answers

Answer:

Its 1/1 or -1/-1

Step-by-step explanation:

Answer:

The slop of the line is 1

Step-by-step explanation:

To find slop of the line you look at rise over run, or the distance from one point to another up then across. In this graph, from the point (0,-3) to (1,-2) you go up one point and across one point. 1/1 = 1 so the slope is 1.

How to convert from decimal to fraction?

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

WE are given that Ellena knows that 1/5 written as a decimal is 0.2.

Thus Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5

By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.

0.2 x 9 = 4.5

Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

On his way to the library , Jeff runs two blocks and then walks three more blocks.Sketch a graph to show the distance Jeff travels compared to time.

Answers

Answer:

Since I can't take a picture, I am going to explain how to draw it.

Step-by-step explanation:

When sketching the graph you must note if jeff is going up the y-axis and along the x-axis. In this case, run means he goes up every minute. So when jeff runs he is going up and 2 minutes have gone by. And when he walks he is going up 3 more but slower so it would double the time. Time would be on the x-axis and blocks would be labeled on the y-axis.

Ms. Kline is baking cookies. She wants to bake cookies for eight friends. Each friend needs to receive at least ten cookies. The recipe she is using makes 55 cookies in one batch.
1. How many batches of cookies does she need to bake to give each person ten cookies?
2. How many cookies will be left over?

Answers

2 batches, there will be 110 cookies made. ms kline is giving 80 away to her friends which leaves us with 30 leftover cookies

8x10=80 so you need at least 80 cookies
55x2=110
110-80=30

So you would need to make 2 batches and you would have 30 cookies left over

Rapid Rental Car charges a $40 rental fee, $25 for gas, and $0.65 per mile driven. For the same car, Capital
Cars charges $55 for rental and gas and $0.75 per mile.
Part 1 out of 2
For how many miles is the rental cost at both companies the same?
The rental costs at both companies are the same at
miles.

Answers

Equation

40 + 15 + 0.25x = 45 + 0.35y

Solution

55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal

subtract 45 from both sides

55 - 45 + 0.25x = 0.35x

10 + 0.25x = 0.35x Subtract 0.25x from both sides.

10 = 0.35x - 0.25x

10 = 0.1x Divide by 0.1

10/0.1 = x

x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.

Let's see if that is true.

Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.

Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.

Conclusion

Both rentals charge the same total amount when each car is driven 100 miles.

The charge is 80 dollars.

Hope this helped! :)

The blind was pulled down to within an inch of the sash so that I could not be seen. When she came out on the doorstep my heart leaped. I ran to the hall, seized my books and followed her. I kept her brown figure always in my eye and, when we came near the point at which our ways diverged, I quickened my pace and passed her. This happened morning after morning. I had never spoken to her, except for a few casual words, and yet her name was like a summons to all my foolish blood.Her image accompanied me even in places the most hostile to romance. On Saturday evenings when my aunt went marketing I had to go to carry some of the parcels. We walked through the flaring streets, jostled by drunken men and bargaining women, amid the curses of labourers, the shrill litanies of shop-boys who stood on guard by the barrels of pigs cheeks, the nasal chanting of street-singers, who sang a come-all-you about ODonovan Rossa, or a ballad about the troubles in our native land. These noises converged in a single sensation of life for me: I imagined that I bore my chalice safely through a throng of foes. Her name sprang to my lips at moments in strange prayers and praises which I myself did not understand. My eyes were often full of tears (I could not tell why) and at times a flood from my heart seemed to pour itself out into my bosom. I thought little of the future. I did not know whether I would ever speak to her or not or, if I spoke to her, how I could tell her of my confused adoration. But my body was like a harp and her words and gestures were like fingers running upon the wires.One evening I went into the back drawing-room in which the priest had died. It was a dark rainy evening and there was no sound in the house. Through one of the broken panes I heard the rain impinge upon the earth, the fine incessant needles of water playing in the sodden beds. Some distant lamp or lighted window gleamed below me. I was thankful that I could see so little. All my senses seemed to desire to veil themselves and, feeling that I was about to slip from them, I pressed the palms of my hands together until they trembled, murmuring: O love! O love! many times.At last she spoke to me. When she addressed the first words to me I was so confused that I did not know what to answer. She asked me was I going to Araby. I forgot whether I answered yes or no. It would be a splendid bazaar, she said she would love to go.And why cant you? I asked.While she spoke she turned a silver bracelet round and round her wrist. She could not go, she said, because there would be a retreat that week in her convent. Her brother and two other boys were fighting for their caps and I was alone at the railings. She held one of the spikes, bowing her head towards me. The light from the lamp opposite our door caught the white curve of her neck, lit up her hair that rested there and, falling, lit up the hand upon the railing. It fell over one side of her dress and caught the white border of a petticoat, just visible as she stood at ease.Its well for you, she said.If I go, I said, I will bring you something.What innumerable follies laid waste my waking and sleeping thoughts after that evening! I wished to annihilate the tedious intervening days. I chafed against the work of school. At night in my bedroom and by day in the classroom her image came between me and the page I strove to read. The syllables of the word Araby were called to me through the silence in which my soul luxuriated and cast an Eastern enchantment over me. I asked for leave to go to the bazaar on Saturday night. My aunt was surprised and hoped it was not some Freemason affair. I answered few questions in class. I watched my masters face pass from amiability to sternness; he hoped I was not beginning to idle. I could not call my wandering thoughts together. I had hardly any patience with the serious work of life which, now that it stood between me and my desire, seemed to me childs play, ugly monotonous childs play.Paragraph 2 is primarily developed throughA.contrasting symbolsB.descriptionC.parallel structureD.ironic commentaryE.metaphor There are more than 3 gallons of gas in Berks car.g > 3A number line going from 2 to 5.
