Answer 1

Answer:

The length of river D is 2550

length of river C is 2550+500=3050

Step-by-step explanation:

Let the river D be 'x'

and the river C is (x+500)

x + x + 500 = 5600

2x + 500 = 5600

2x = 5600 - 500

2x = 5100

x = 5100/2

x = 2550

The length of river D is 2550

length of river C is 2550+500=3050

Answers

Answer:

$19.07

Step-by-step explanation:

Look at image above...

The total cost of the meal is $19.065.

What is the percentage?

In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.

A restaurant bill before tax is $15.50.

If the sales tax is 8% and a 15% tip is added.

The total cost of the meal is;

[tex]\rm Total \ cost = Bill \ amount + Sales \ tax + Tip\\\\ Total \ cost = 15.50 + 15.50 \times \dfrac{8}{100} + 15.50 \times \dfrac{15}{100}\\\\ Total \ cost = 15.50+1.24+2.32\\\\ Total \ cost = 19.065[/tex]

Hence, the total cost of the meal is $19.065.

Use the linear inequality + 8y 24 for Part A, Part B, and Part C. Part A: Determine the boundary line, and state whether the line will be dashed or solid. Part B: Which half-plane should be shaded? Describe where you should shade using the language "above" or "below" the line. Part C: Show your work for Part B to show how you determined which half-plane to shade.​

Answers

Answer:

Given inequality:  [tex]x+8y\leq 24[/tex]

Part A

Solid line: ≤ or ≥

Dashed line: < or >

Therefore, the line will be solid.

Part B

Shading above the line: y > or y ≥

Shading below the line: y < or y ≤

Therefore, shade below the line.

Part C

Make y the subject to determine where to shade.

Given inequality:  

[tex]x+8y\leq 24[/tex]

Subtract x from both sides:

[tex]8y\leq 24-x[/tex]

Divide both sides by 8:

[tex]y\leq 3-\dfrac18x[/tex]

[tex]\\ \rm\Rrightarrow x+8y\leqslant 24[/tex]

#Part A

#Part B

Latanya was asked to determine if (375,4) lies on the circle with radius 7 centered at (0.-2). what is her error?

(3/5)2 + (4 - 2)2 = 49
45+ 4 = 49
the point (375,4) lies on the circle
with radius 7 and centerd at (0,-2). what is her error

Answers

The point (3/5,4) would lie on the circle if it makes the equation of the circle to be true

Latansha's equation of the circle is wrong

How to determine her error?

The given parameters are:

Center = (a,b) = (0,-2)

Radius, r = 7

The equation of a circle is:

[tex](x - a)^2 + (y - b)^2 = 0[/tex]

This gives

[tex](x - 0)^2 + (y + 2)^2 = 0[/tex]

Rewrite as:

[tex]x^2 + (y + 2)^2 = 0[/tex]

In Latanya's first step, we have:

[tex]x^2 + (y - 2)^2 = 0[/tex]

By comparing her first step with x^2 + (y + 2)^2 = 0, we can see that her equation is wrong

Hence, Latansha's error is that she determine the equation of the circle, wrongly.

V=3.1.4*5^2*10

Answers

Answer:

Step-by-step explanation:

The volume of a cylinder is the area of the circle times the hight of the cylinder.

Thus...

3.14*5^2*10=785

The reason it is 5 and not 10 is because it gives you the diameter in the word problem and the equation asks for the radius.

So you know that the radius is always half the diameter and half 10 which gives you 5.

Matthew sat inside his car in the parking lot of Arnold's Chicken Palace. He arrived early for his job interview, and he wanted to make sure his attitude was stellar before going inside the restaurant. Unfortunately, he felt petrified. "I can't do this," he told his mother over the phone. "Yes, you can, Matty," his mother said. Matthew's hand shook while he pressed his cell phone more tightly against his ear. "All my potential employers have rejected me," he said. "What if nobody hires me?" "Matthew, you can't think small. Remember who you are, remember your abilities, think about what you want, and then go after it. Shout at it if you have to." "Shout at my potential job?" "Sure, why not?" his mother replied. "I believe in you, and you can believe in yourself too." After Matthew ended his phone call with his mother, he spent a few moments calming himself down. Come on, Matt, you can do this, he thought to himself. You'll be the best manager Arnold's Chicken Palace ever had. While taking deep breaths, he clenched his fists and felt strength surge through his muscular arms. He closed his eyes and thought about all the other jobs he had interviewed for but did not get. He thought about his bills piling up. He knew this interview would be a very important one. Then he shouted as loudly as he could, "This job is mine!" Matthew opened his eyes and saw a woman and a little girl walking past his car. They both scurried away quickly. Embarrassed, Matthew waved at them and cleared his throat. The day after his interview, Matthew received a phone call from the owner of Arnold's Chicken Palace. "I am very pleased to offer you the position of manager at my restaurant," the owner said. "You were a very impressive candidate for the job," he added. "How did you become such a confident person?" Matthew clenched his fist and tried to not shout with excitement. With a smile, he replied, "I guess I just believe in myself."What is the best summary of the passage? A. When Matthew is rejected by other employers, he decides to interview for the post of a manager at Arnold's Chicken Palace. Though Matthew is nervous, he decides to call his mother, who tells him that he should think of all the bills he has to pay. Mathew then closes his eyes to calm himself, gives the interview with confidence, and gets hired as a manager. B. Matthew is nervous about his job interview at Arnold's Chicken Palace for the post of manager and remembers how badly he needs the job to pay his bills and starts getting nervous. Then he recalls his mother's advice to believe in oneself and takes a minute or two to assure himself that all will be fine. He realizes that it is important to stay calm during stressful times. C. Mathew, who has been rejected by several employers, is nervous about his interview at Arnold's Chicken Palace and calls his mom who advises him to be confident, believe in himself, and go after the job with determination. Following this, Matthew confidently interviews at Arnold's and is offered the job. He realizes that belief in oneself surely leads to success. D. When Matthew begins to panic before his interview at Arnold's Chicken Palace, he calls his mother for advice. Hearing his mother's voice and her advice to believe in himself makes Matthew feel confident. Mathew tells himself that he would do well in the interview, and that he would be the best manager at Arnold's Chicken Palace once he is hired.
