Andrea earned 200 points on a school assignment. Because the
assignment was turned in late, the score was reduced to 20 points.
What was the percentage decrease in the score?
Symbol requiere

Answers

Answer:

It was approximately a 9% decrease. (If you need to round to the nearest tenth, 9.1. If you need to round to the nearest hundredth, 9.10).

Step-by-step explanation:

I am going to assume that the question means that Andrea could have earned 220 points on the assignment, but instead because the assignment was late, she was marked down 20 points. (Reduced to 20 points is kind of awkward wording).

Given that, 20 divided by 220 comes out to 0.0909 repeating.

0.09, as a percentage, is 9%. (Again, 0.0909, 9.09%, could be rounded up to 9.1%).

The equations shown represent two altitudes of a triangle. y = x+1 and y = −2x−1 What are the coordinates of the orthocenter of the triangle?

Answers

Answer:

The coordinates of the orthocenter of the triangle is;

(-2/3,1/3)

Step-by-step explanation:

To find the coordinates of the orthocenter, all we have to do is solve for x and y of the given altitudes

We can get this by solving both equations simultaneously

Simply equate the two y’s

x + 1 = -2x-1

x + 2x = -1-1

3x = -2

x = -2/3

To get y, simply substitute into any of the equation, the value of x

y = -2/3 + 1

y = 1/3

Em quantos meses um capital de R$4.000,00 aplicado a uma taxa de juros simples de 29,3% ao ano, renderá de juros o valor de R$586,00? Insira sua resposta 3.Se uma pessoa necessitar de R$100.000,00 no futuro e depositar hoje R$90.909,09 em uma aplicação com taxa de juros simples de 12% ao ano, levará quantos meses para resgatar o dinheiro desejado?

Answers

Responda:

6 meses

10 meses

Explicação passo a passo:

Dado que:

Principal = 4000

Juros = 586

Taxa (r) = 29,3% ao ano = 0,293

Juros simples = principal * taxa * tempo

586 = 4000 * 0,293 * t

586 = 1172t

t = 586/1172

t = 0,5 anos

Tempo = (0,5 * 12) = 6 meses

B.)

principal = $ 90909,09

Montante final = 100.000

Taxa (r) = 12% = 0,12

Usando a fórmula:

Quantidade final = p (1 + rt)

Taxa = r; t = tempo

100000 = 90909,09 (1 + 0,12t)

100000 = 90909,09 + 10909,0908t

100000 - 90909,09 = 10909,0908t

9090,91 = 10909,0908t

t = 9090,91 / 10909,0908

t = 0,8333334

Número de meses:

0,8333334 * 12

= 10 meses

A company has to buy computers and printers. Each computer costs $550 and each printer costs $390. If
the company spends $8160 and buys a total of 16 machines, how many of each did it buy?
a. Let Statements:
b. Write the system:

Answers

Answer:

Answer:the company bought 12 computers and 4 printers.

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of computers that the company bought.

Let y represent the number of printers that the company bought.

The company buys a total of 16 machines. It means that

x + y = 16

Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that

550x + 390y = 8160 - - - - - - - - - - 1

Substituting x = 16 - y into equation 1, it becomes

550(16 - y) + 390y = 8160

8800 - 550y + 390y = 8160

- 550y + 390y = 8160 - 8800

- 160y = - 640

y = - 640/ - 160

y = 4

Substituting y = 4 into x = 16 - y, it becomes

x = 16 - 4

x = 12

Answer:

The company bought 12 computers and 4 printers.

Step-by-step explanation:

Let x represent the number of computers that the company bought.

Let y represent the number of printers that the company bought.

The company buys a total of 16 machines. It means that

x + y = 16

Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that

550x + 390y = 8160 - - - - - - - - - - 1

Substituting x = 16 - y into equation 1, it becomes

550(16 - y) + 390y = 8160

8800 - 550y + 390y = 8160

- 550y + 390y = 8160 - 8800

- 160y = - 640

y = - 640/ - 160

y = 4

Substituting y = 4 into x = 16 - y, it becomes

x = 16 - 4

x = 12

How do you rearrange an equation so that the X is alone ?

Example: (g=6x),
(Z=m-x)
Or (u=2x-2)
Please help !

Answers

For the g=6x you would have to divide the 6 from both sides so it would end up being x=g/6. For Z=m-x you can add the x to both sides making it z+x=m and then subtracting the z from both sides making it x=m-z. Then for u=2x-2 you would have to add 2 to both sides making it u+2=2x and then divide 2 from both sides making it x= 2+u/2.

A rectangular soccer field is 80 meters wide and 110 meters long. The coach asks players to run from one corner of the field to the opposite corner diagonally. How far do the players have to run?

Answers

Answer:

Step-by-step explanation:

Goven the length of the field = 110m

Width = 80m

The length of the diagonal is expressed using the pythagoras theorem;

d² = l² + w²

d² = 110² + 80²

d² = 12100 + 6400

d² = 18500

d = √18500

d = 136.01

Hence the players have to run 136.01m diagonally

Emma Abrams choked with deep conviction. "You mean everything to me. I can't live without you!" This was the part of the script where Emma was supposed to burst into real tears, yet her big blue eyes were like a desert. Emma tried to think of something despairing, like the time her toddling brother sliced his finger on a piece of broken glass while she was watching him, or the devastation she felt when learning that her cat had run away. These sad reflections did nothing to moisten her eyes. "Well, don't panic, Emma," she coached herself. "When it counts in the audition today, you'll cry real tears. You've just got to!"2It was difficult to study the script in the car with all of the bumps, turns, and sudden stops typical of trips into New York City, but Emma was determined to make sure that she had each line memorized word for word. She had studied every line nonstop since her agent had called with the good news. It was her first Broadway audition and her entire family had helped her to prepare. Her older sister helped her choreograph a dance, her father improvised with her by playing the part of Grandpa at the dinner table, and her little brother listened to her read her lines. No one was more constant in helping Emma realize her thespian ambitions than her mother, though. Mom was the one who accompanied Emma to her piano, voice, dance, and drama lessons each weekday after school. She went to every audition and performance with Emma, and Emma wished with all her heart that Mom was here with her now.3Emma appreciated her mother's constant companionship and support of her acting career. Her mother was always present backstage at the Dutch Apple Dinner Theater where Emma was currently starring in Annie on Friday and Saturday nights. Mom was the driving force behind her daughter's acting career, but she refused to drive in New York City. The big city frightened Mrs. Abrams and made her jittery. Since she was already nervous about Emma's big audition, Mrs. Abrams thought it best if she just stayed home. Emma tried to behave like a grown-up when her mother told her she wouldn't be going, but inside Emma felt panicky and alone.4Emma's father continued to navigate through the heavy traffic streaming into the city. As the skyline of New York City came into view, Emma started to cry. She knew she should have begged her mother to come with her but now it was too late! Her father looked into the rearview mirror and said, "Wow, honey! If you can do that during the audition, you're a shoo-in." He was genuinely impressed and didn't realize that her tears were real. Emma stared out the window, feeling sorry for herself.5Emma watched her dad hand his car keys to the parking attendant. They walked in silence for several blocks, with Emma holding her father's arm. She wanted to ask her father to come in to the audition with her, but she knew he'd be uncomfortable around a bunch of stage mothers. Emma soon found herself being escorted into a crowded lobby. She waved good-bye to her father and disappeared inside the theater.6When she emerged from the audition several hours later, Emma was exhausted but triumphant. "I don't ever want Mom to come to an audition where I have to cry again!" she declared as they left the theater together.7Knowing his daughter's flair for the dramatic, Mr. Abrams quickly said, "Now don't be angry with your mother because she couldn't come today, Emma. That's not fair."8Emma realized her father misunderstood her, so she explained that when she'd cried in the car earlier, it wasn't an act; she was genuinely upset that her mother wasn't with her. "When I went into the audition, all the other girls' mothers were there, but I was all alone. I was terrified without Mom there, so when they called on me to read my lines, I was on the verge of tears anyway. I just thought about how alone I felt without Mom there, and the tears came pouring down. It was perfect timing, and I think I just might get the part! Mom is the secret to my success." She bowed and curtsied to an imaginary audience, saying "Thank you, Thank you."9Mr. Abrams smiled and said, "I'm not sure, but I think that just this once, your mother will be extremely happy to hear that she made you cry."How does the resolution of the story develop the theme? A. Emma was able to make herself cry with hard work and dedication. B. Emma finally realized she did not need anyone else to be successful. C. Emma concluded that her father was just as supportive as her mother. D. Emma understood that it was not right for her to be angry with her mother.
