can you please explain slope, the y-intercept, how to find the equation and how to graph it properly?​

Answers

Answer:

Slope is a line on a graph, you find slope with the m=yx+b equation. Y intercept is the point that the line crosses the y axis at, it is represented by b. X and Y in the equation are your coordinates. You graph it by starting at your y-intercept and going up in a straight line following the slope calculated.

Mr. Mohr wants to build a rectangular patio using concrete tiles that are 12 square inches. The patio will measure 13.5 feet by 43 feet. What is the area of the patio? How many concrete tiles will he need to complete the patio?

Answers

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet   [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷  12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

Answer:

49 tiles

Step-by-step explanation:

Answer: He will need 49 tiles.

Step-by-step explanation:

Given: The patio will measure 13.5 feet by 43 feet.

Area of patio = 13.5 feet x 43 feet [Area = length x width]

= 580.5 sq. feet

Since area of each concrete tile = 12 sq. inch

Number of concrete tiles required to cover patio = (Area of patio) ÷ (area of each concrete tile)

= 580.5 ÷ 12

= 48.375 sq. inch ≈49

Hence, he will need 49 tiles.

Willie left the mall and traveled toward the town hall at an average speed of 40 km/h. Gabriella left two hours later and traveled in the opposite direction with an average speed of 70 km/h. Find the number of hours Gabriella needs to travel before they are 410 km apart.

Answers

Answer:

Gabriella need to 2.45 hours of travelling to be 410km apart from Willie.

Step-by-step explanation:

In order to make them 410km apart and the time included in it is to be found

we proceed as

Willie left the mall earlier and Gabriella left two hours before

so willie has travelled for 2 hours while Gabriella was still at the initial point

with this logic we find the hours Gabriella needs as follows

              Willie               Gabriella

              ←←←←←←←←  →→→→→→→→→→

                40km/h            70km/h      

                 X hours             X+2 hours

40*x+70(x+2) = 410

40x+70x + 140=410

110x=270

x=270/110

x= 2.45hrs

Nick has $3.90 in quarters and dimes, and the total number of coins is 27. How many quarters and how many dimes? Can I have some help with formatting?

Answers

Answer:

There are 19 dimes and 8 quarters

Step-by-step explanation: Q= Quarter and D=dimes

q+d= 27;   q=.25 and d=.10;    

.25q+.10d= $3.90

q= 27-d

.25(27-d)+.10d=3.90    >Distribute .25 through the parenthesis

= 6.75-.25d+.10d=3.90  >Combine like terms

= -.15d=3.90-6.75 >Subtract 6.75 from both sides of the equation

=  -.15d=-2.85   >Subtract

=  d=19  >Divide both sides by -.15

q= 27-d>>>>> q= 27-19

q= 8

If x^2+x =3^2/3+3^-2/3 then prove that 3x^3+9x-8=0

Answers

x^2 + 2 = 3^2/3 + 3^-2/3

x^2 = 3^2/3 + 3^-2/3 - 2

x = √(3^2/3 + 3^-2/3 - 2)

x = 0.748888296

Substitute for x in 3x^3 + 9x - 8:

3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.

So it is proved.

B. Yes. Alternate Interior Angles Converse
C. Yes. Alternate Exterior Angles Converse
D. Yes.Consecutive Interior Angles Converse
E. Yes. Corresponding Angles Converse

Answers

Answer:

B. Yes. Alternate Interior Angles Converse

Step-by-step explanation:

The two angles shown in the figure above are alternate interior angles. Each is located within the two parallel lines intersected by the transversal, and they also lie on opposite side of the transversal.

The marked alternate interior angles are congruent. Therefore, lines r and s are parallel. So, by the Alternate Interior Angles Converse, lines r and s are parallel.

Therefore, the right response to the question is:

"B. Yes. Alternate Interior Angles Converse".

0 Ç. f(x) = 7 + 5x
O D. f(x) = 12 + 5x

Answers

Answer:C. f(x)=7+5x

Step-by-step explanation:

12=5(1)+n

12=5+b

-b+12=5

-b=5-12

5-12=7

-b=7

f(x)=7+5x

I know this because I just answered this question and got it right

The equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The table is given,

From the data given in the table:

12 = 5(1)+n

12 = 5+b

b = 7

The function would be:

f(x) = 7 + 5x

Thus, the equation of the function is f(x) = 7 + 5x option (C) f(x) = 7 + 5x is correct.

What is the solution to the equation 13.7y – 10.6 = 6.2y + 19.4

Answers

Answer: hope this helps :)))

y=4

Step-by-step explanation:

Step 1: Subtract 6.2y from both sides.

13.7y−10.6−6.2y=6.2y+19.4−6.2y

7.5y−10.6=19.4

Step 2: Add 10.6 to both sides.

7.5y−10.6+10.6=19.4+10.6

7.5y=30

Step 3: Divide both sides by 7.5.

7.5y/7.5 = 30/7.5

y=4

For some reason, in our history class, there are 14 boys than there are girls. If a total of 32 students are in the class, how many boys and how many girls are there?

Answers

Answer:

There are 23 boys and 9 girls in the class

Step-by-step explanation:

The given information is that the number of boys = 14 + The number of girls

The total number of boys and girls = 32

Let the number of girls = x

Therefore, we have;

The number of boys = 14 + x

The total number of boys and girls = 32 = The number of boys + The number of boys

The number of boys + The number of boys = 14 + x + x = 14 + 2·x

∴ The number of boys + The number of boys = 32 = 14 + 2·x

14 + 2·x = 32

2·x = 32 - 14 = 18

2·x = 18

x = 18/2 = 9

x = 9

Therefore, the number of boys is 14 + x = 14 + 9 = 23 boys

The number of boys = 23 boys

The number of girls = x = 9 girls

the number of boys = 23 boys

The number of girls = x = 9 girls

The number of girls = 9 girls

Therefore, there are 23 boys and 9 girls in the class.

Find the constant ofproportionality and write an equationrelating t and r.t =[?]/[?] Author looks at how kids can face tight spotsBy Mary Quattlebaum, Washington Post on 11.19.18Torrey Maldonado is the author of the novel "Tight" which deals with children and their power to make choices.Torrey Maldonado likes to ask this question when he talks at schools about his new novel, "Tight." "Every kid's hand goes up," said Maldonado, in a phone interview from his home in Brooklyn, New York. "They all have an answer: super speed, super strength, flying." In his book, the main character, Bryan, wishes he was as smart as the superheroes Black Panther and Batman, who think ahead and figure things out. His best friend, Mike, wants to be as strong as Luke Cage. But Maldonado reminds kids that they already have an important power: the power to choose. Maldonado knows that can be easier to say than to act on. He, too, faced tough choices in middle school, just like Bryan. He knows the choice is rarely between an absolute right and an absolute wrong. Take Bryan's friend, for example, Mike, who is smart and likable. Both boys love hanging out for hours, reading comic books and discussing superheroes. But Mike has another side. He talks Bryan into doing stuff that Bryan has always thought is wrong, such as skipping school and jumping turnstiles to ride the subway without paying. When Bryan pushes back, however, Mike makes fun of him for being "soft" and scared. Bryan doesn't want to lose his only real friend, and he doesn't want others in his Brooklyn neighborhood, especially his tough dad, to see him as "soft." When Mike's risk-taking gets another kid into big trouble, Bryan doesn't know what to do or how to step away from the friendship. When Maldonado talks to students about his book and their choices, he says he often feels as if he's "talking to a younger me." Growing up in a neighborhood like Bryan's, Maldonado knew kids like Mike, and now that he's a middle-school teacher, he sees his students faced with similar choices. "Most of us have had Mikes in our lives," he said. "A bully isn't just someone who steals your lunch money; some are cool and popular, like Mike. How do you deal with them?" Maldonado worked hard to create Mike as a complicated character. He didn't want Mike to be a caricature of a bad guy, but to have positive traits as well as flaws in order to make him more believable. When he was a kid, Maldonado had someone who tried to show him the power of choice: his mother. She encouraged his writing since he was "in diapers," he said with a laugh. Her own writing inspired him. "I loved it when she would open her spiral notebook and ask my opinion about a poem she had written, or a quote" that she liked, he added. When his mom realized she was the model for Bryan's strong, loving mother in the book, she was so touched that "she started crying," Maldonado said. The author is working on a new novel, about a mixed-race boy. As he juggles teaching and writing, Maldonado says he sometimes wishes he had a certain superpower. "Super speed like the Flash," he said. "That way, I could write all the stories I have in my head."Write a short paragraph that explains the central idea of the article.
