Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets less then Elian. Let A be the number of tickets Alberto won and e be the number of tickets Elian won.

Answers

Answer: See explanation

Step-by-step explanation:

Number of tickets Elian won = e

Number of tickets Alberto won = A = e - 10

Therefore, Elian + Alberto ticket = 100

e + (e - 10) = 100

2e - 10 = 100

2e = 100 + 10

2e = 110.

e = 110/2

e = 55

Elina has 55 tickets

Alberto has 55-10 = 45 tickets

a) a train leaves westchester at 6.30. What time should it arrive at middlewich? b) Kate lives in Northton. She works in southam and starts works at 9am. What is the time of the latest train that she can catch to get to work on time? C) how long does the train take to travel from the westchester to east wick?

Answers

Answer:

a). 6:51

b). 6:30 am

c). 34 minutes

Step-by-step explanation:

a). Train leaves Westchester at 6:30.

    From the arrival - departure table in column (2),

    Arrival time of the train at middlewich = 6:51

b). Kate has to reach Southam before 9:00 am

    Therefore, time of the latest train that she can catch to get to work on time is 6:30 am

     By this train she can reach at 07:19 at Southam.

c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00

                                                                                         = 00:34

                                                                                         ≈ 34 minutes

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?

Answers

Answer:

i think 150

Step-by-step explanation:

Answer:  $30.00

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

0.20 x $25.00=$5.00.

$25.00 + $5.00 = $30.00.

You invest $4000 into an account that compounds interest on a quarterly basis at 3%. how much money will you have after 5 years? Compound interest formula: A = P(1+r/n)^(nt)

Answers

Answer:

26666.6

Step-by-step explanation:

So sorry if this is wrong i tried

The amount after 5 years is $4,644.74.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P[tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $4000

n = 4

r = 3%

t = 5 years

A = 4000 [tex](1 + 0.03/4)^{20}[/tex]

A = 4000 x [tex]1.0075^{20}[/tex]

A = $4,644.74

Thus,

The amount after 5 years is $4,644.74.

You are to write an essay arguing the right OR wrong for stealing from (Papa) Esperanza's family. Write your essay after you've chosen a side - BANDIT or PAPA. Be sure to use evidence from the book to DEFEND your position (argument). Our land is alive, Esperanza, said Papa, taking her small hand as they walked through the gentle slopes of the vineyard. Leafy green vines draped the arbors and the grapes were ready to drop. Esperanza was six years old and loved to walk with her papa through the winding rows, gazing up at him and watching his eyes dance with love for the land. This whole valley breathes and lives, he said, sweeping his arm toward the distant mountains that guarded them. It gives us the grapes and then they welcome us. He gently touched a wild tendril that reached into the row, as if it had been waiting to shake his hand. He picked up a handful of earth and studied it. Did you know that when you lie down on the land, you can feel it breathe? That you can feel its heart beating? Papi, I want to feel it, she said. Come. They walked to the end of the row, where the incline of the land formed a grassy swell. 2 Papa lay down on his stomach and looked up at her, patting the ground next to him. Esperanza smoothed her dress and knelt down. Then, like a caterpillar, she slowly inched flat next to him, their faces looking at each other. The warm sun pressed on one of Esperanzas cheeks and the warm earth on the other. She giggled. Shhh, he said. You can only feel the earths heartbeat when you are still and quiet. She swallowed her laughter and after a moment said, I cant hear it, Papi. Aguntate tantito y la fruta caer en tu mano, he said. Wait a little while and the fruit will fall into your hand. You must be patient, Esperanza. She waited and lay silent, watching Papas eyes. And then she felt it. Softly at first. A gentle thumping. Then stronger. A resounding thud, thud, thud against her body. She could hear it, too. The beat rushing in her ears. Shoomp, shoomp, shoomp. 3 She stared at Papa, not wanting to say a word. Not wanting to lose the sound. Not wanting to forget the feel of the heart of the valley. She pressed closer to the ground, until her body was breathing with the earths. And with Papas. The three hearts beating together. She smiled at Papa, not needing to talk, her eyes saying everything. And his smile answered hers. Telling her that he knew she had felt it.
