Answers

Answer 1

Answer:

yes every values are increasing constantly by 2.5

Answer 2

Answer:

Step-by-step explanation:

Note that for each unit increase in x, y increases by 2.5.  The constant of proportionality is therefore 2.5:

y = 2.5x

All of the y-values are a constant multiple of the corresponding x-values, so the relationship is a proportional one.

Answer:

y=3/4x

Step-by-step explanation:

From the origin (0,0) count the rise to the next point (3) and then the run (4) leaving you with 3/4 as your slope.

well, we see that it is a linear function.

so, we should make an equation that follows:


y = mx + b


b = y intercept, which is 0 because it connects at the origin.


m is the slope, which is rise/run.

we find a point at ( 0.7 , 0.5 ).

the rise is 0.5, and the run is 0.7, so we do

0.5/0.7

and we get 0.714285714285714, which we can round to 0.7143 for the m.

we have everything we need.


so,


y=0.7143x


(the b is 0, so we don’t have anything else to add).

Answers

it’s a linear function so,

y = mx+b

b is 0.

m is rise/run, which is 6/3, which is 2.

so

y=2x


hope this helps!

Answer:

y = 2x

Step-by-step explanation:

the equation of proportional relationships are in the form y = mx, where m is the slope.

this means you need to solve the slope.

to find the slope, find 2 random points and do change in y divided by change in x.

for example, (3, 6) and (0, 0)

this would be (6 - 0)/(3 - 0) = 2

this means m = 2

so the equation is y = 2x

Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in.

What is the area of the curved surface of the trash can she will need to decorate?


A trash can with radius 4 inches and height 12 inches.

Answers

12 in =30 cm

4 in = 10 cm

area of 1 circle= 3.14×10×10= 314 cm²

area of 2 circle= 314×2= 628 cm²

if u unfold the trash can the biggest surface(not the circle) will become a rectangle with two circles(628 cm²)

length of rectangle = circle circumference

= 2×3.14×10

=62.8 cm

area of rectangle= 62.8 × 30 = 1884 cm²

total area= 1884 + 628 = 2512 cm²

Answer:

2512 cm²

1) the equation for finding the perimeter of a rectangle is P=2L+2W. so, P=2(120)+2(53). P=240+106. P=346.

2) The equation is P=2L+2W. P=2(3)+2(2). P=6+4. P=10

3) the equation for finding the perimeter of a square is P=4s. So P=4(15) P=60

Answers

Answer:

She has fulfilled about 91.6666 repeating

Step-by-step explanation:

If half of her sales were fulfilled in January, then that is 50% or 0.5. Then if you take 5/12 then it = 0.41666666, add the two decimals together and you have 0.916666 repeating. If you want to turn that into a fraction it would be 9/10 by rounding down due to the decimal.

Find the quotient. Express your answer as a simplified fraction. 3/10 divided by 3.8

Answers

Answer:

4/5



Step-by-step explanation:

3/10÷3/8

Simplifying 24/30, the answer is

=4/5

The value of the quotient of ''3/10 divided by 3.8'' as a simplified fraction would be 3/38.

Given that;

The expression is,

3/10 divided by 3.8

Now it can be divided as,

3/10 divided by 3.8

3/10 ÷ 3.8

3/10 × 1/3.8

3/38

Therefore, the value of the quotient as a simplified fraction would be 3/38.

How does the writer use structure and language to persuade her readers and support her feelings about immigration?Dear Editor,I have never taken the time to write a letter to the editor, but something happened that lit a fire in me. Last week, as my best friend Areliss and I headed to class, a group of college protesters blocked our path. Their signs read "GO HOME" and "ILLEGALS LEAVE." They shouted, "Send them home!" These protesters couldn't have known what Areliss felt as they shouted and waved pamphlets in our faces like tattered flags. But, I know their words were bullets to Areliss's heart. I wanted to fire back to the protestors: Where are your ancestors from?Areliss came to the United States illegally, but she didn't do it intentionally. She was a baby. Her parents, seeking a better life, failed to follow the established immigration procedure, and they slipped into our country undetected. Once here, they raised Areliss, who would grow up never knowing any other home but America.Under DACA (Deferred Action for Childhood Arrivals), Areliss has been granted the temporary opportunity to remain here while she completes her college education. DACA ensures, at least for a while, that she will not be deported to a country she has never visited in her entire life.The term "DREAMers" refers to an act that would have protected these immigrant children if they attended college or served in the military. The DREAM Act did not pass, but its name has remained. DACA recipients have a dream: they dream that their lifelong contribution to the United States will one day be recognized, and they will be permitted to stay in the country they have always called home.Now, DACA is ending. Those who oppose DACA say it encourages illegal activity, weakens our borders, and goes against the Constitution. I understand their concerns. In an era of heightened security, we must do our utmost to keep this great nation safe. That includes establishing a healthy monitoring system for immigration.But, those who oppose DACA, who wield protest signs and who want to build walls, have never felt the dreaded doom of deportation. They forget that our long and colorful history has been built by many immigrantsincluding the immigrants who fought for and founded our country. They forget that Lady Liberty stands as a beacon, asking for the tired, the poor, and the huddled masses yearning to breathe free. We have a responsibility to them.To send DREAMers away is to deny that responsibility. Programs like DACA exist to keep the American dream alive.Yes, Areliss is a DREAMer. But I, too, have a dream. My dream is that DACA will be reinstated. My dream is that Areliss will be invited to stay in the country she has known as home since she was a baby and live out her dreams in the country she loves.Sincerely,Brittany Taylor Please help me on this math problem
