Answer:
First we know that the room is a rectangular prism with measures:
width = W = 15ft
length = L = 23ft
height = H = 8ft
We want to paint the room (i suppose that we paint the four walls and the roof)
The area of each two of the walls the width times the height:
A = (15ft)*8ft = 120ft^2
And we have two of these walls, then the total area is:
area = 2*120ft^2 = 240ft^2
The area of each one of the other two walls is the height times the length:
A = (23ft)*8ft = 184ft^2
And we have two of these walls, then the total area is:
A = 2*184ft^2 = 368ft^2
The area of the roof is equal to the length times the width.
A = 23ft*15ft = 276ft^2
Then the total area we need to paint is:
area = 240ft^2 + 368ft^2 + 276ft^2 = 884 ft^2
a) We know that one gallon can cover 250 ft^2
Then to cover 884 ft^2 we need:
N = (884 ft^2)/(250 ft^2) = 3.536 gallons of paint
b) Knowing that each gallon costs $28, and that we need 3.536 gallons of paint to paint the room, the total cost is:
3.54*$28 = $99.008 = $99.01
Now if for some reason you only can buy paint in whole numbers, then you can not buy exactly 3.536 gallons, then you need to buy 4 gallons, and in this case, the total cost will be 4 times $28
cost = 4*$28 = $112

I am not allowed to use a calculator, by the way.
Step-by-step explanation:
(38+45)+9*2+3-59+((4/2)*3+8*5)=
83+18+3-59+(6+40)=
83+18+3-59+(6+40)=
83+18+3-59+46=
(83+18+3+46)-59=
150-59=91
I'm not sure if this is correct but it should be. Is it 4/2*3 or (4/2)³?If it is (4/2)³ the result would be 93.
Caleb has 3 packs of colored pencils. Each pack has x pencils in it. After Ryan gives him 6 more
colored pencils, he has a total of 27 pencils.
Answer:
3 × x + 6 = 27 - 6 = 21 divided by 3 = 7 so 7 pencils in each box. 6 divided by 3 = 2 which means 7 + 2 = 9 pencils in the box total after Ryan gives 6 pencils to caleb.

Answer:
Step-by-step explanation:
Angle x is what I call "point to point" with the angle that measures 95 degrees. Because of this, they are vertical (the vertex of an angle makes a "v"; hence, the reason I call them point to point). Vertical angles are congruent. That means that they have the same measure. If x is vertical to an angle that measures 95 degrees, then x also measures 95 degrees.
Answer:
x is 95 degrees.

You mess with my heart enough for me to hate
I had to even start to debate if you were a good choice
I do not think so, before this I was happy
Until you decided to cheat like you do with everything else
My heart went into two just like how I left
The only one to fix it is you but I keep it broken
I will consider this a token for all the stuff I have done for you
My love will not go away but I will make it leave
Just like you did to me, you did not love me
I could see by the way you looked at anyone else
If you decide to love me I will not return the feeling
That is how my heart will feel because it will not return
You broke it and me I do not see you as human
Rather as a cheater, liar, and a h.oe
I will never love someone like that
But I will never try and treat them like you did me
I have a heart I think you break guys to get your own
All of the shattered hearts that will take to create you one
I will never think of this as a bad choice rather something I needed to do.
Goodbye forever don't even look at me, my queen.

Community- jocelynn johnson
Community is a family,
Someone who help people when in need,
But this is not a community,
This is a place where people feel like they don’t belong,
A place where people have to look around
The corner to make sure their safe,
It is for the days that growing,
For the life that’s growing,
For the changes we made that hurt our loved ones,
That may cause stress throughout the day,
And may cause you to not
Wanna play,
U say your safe,
But the truth is you might get killed at the end of the day,
Why I say,
Cause this neighborhood’s not safe,
And your running on the streets all day,
This community has changed,
All throughout the day,
Cause kids are always joining gangs,
I just wish everything would go back to
Being the same.

Determine if the graph of the function opens up or down. Explain how you know
Answer:
Opens up
Step-by-step explanation:
x^2+2x-15
Standard form: ax^2+bx+c
If a<0, then the graph opens down
If a>0, then the graph opens up.
In this case: 1x^2+2x-15
a=1
Since 1>0 then the graph opens up.

If y varies directly with x. and y=10 when x=5.6, find the value of y when
X=3
Answer: 5.3571
Step-by-step explanation:
The formula used to calculate direct proportion is: y = kx
We will find the constant of proportionality when y=10 and x=5.6. This will be:
y = kx
10 = 5.6k
k = 10/5.6
k = 1.7857143
The value of y when X=3 will be:
y = kx
y = 1.7857143 × 3
y = 5.3571

What is the measure of x and what is the reasoning you used
Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108
