HELPP ME!! Ya'll brainly has answers for this question but they're all different answers!! I'm so unsure! One of the offices at the company was being repainted. Riley’s mother challenged him to figure out how many quarts of paint would be needed. The office is 16 ft long and 12 ft wide, and the height of each wall is 10 ft. The office floor, ceiling, and door are not being painted, and there are no windows in this office. The door opening measures 3 ft by 8 ft. One quart of paint covers 2 100 ft . How many quarts of paint are needed to paint the room, if only full quarts can be purchased? Show your work.
Answer:
3.8 quarts

The answer is 570 because if you multiply 38 times 15 = 570 so it is 570. Thank you for answering to hope this helps you if you need more help contact me!
Answer:
$5.70
Step-by-step explanation:
Since it is 15% to make it a decimal you would move the decimal 2 places to the left to make it 0.15 and then multiply like this 38(.15) which is 5.7. So, shipping and handling is $5.70.

y=6x-11
-2x-3y=-7
find the solution plz
if you solve using subsitution, the point form would be (2,1) and the equation form = 2, y=1
Answer:
x = -2
y = -23
(x, y) --> ( -2, -23)
Step-by-step explanation:
y = 6x - 11
-2x - 3y = -7
***What you need to do is substitute the "y" with what has been given to us which is "6x - 11"***
-2x - 3(6x - 11) = -7
Now what you need to do, is use the distributive property (multiply what is in the parenthesis "6x - 11" by what is outside of it "3").
-3 × 6x and -3 × -11
-18x and 33
Now we have......
-2x - 18x + 33 = -7
Now we can combine like terms (put the numbers that are the same together - variables with variables, and whole numbers with whole numbers)
-2x - 18x = -20x (2 negatives added together gives u a result of a bigger negative number)
-20x + 33 = -7
Now we need to subtract 33 on both sides
-20x + 33 - 33 = -7 - 33
-20x = -40
Now we need to divide by -20 on both sides to isolate the variable
-20x ÷ -20 = -40 ÷ 20
x = -2
Now that we have what "x" is, we can use that to find what "y" is....
y = 6x - 11
Substitute the "x" with the answer we got "-2".
y = 6(-2) - 11
y = -12 - 11
y = -23
x = -2
y = -23
Now we can check our work
y = 6x - 11
All we need to do is substitute the "x" and "y" with the answer we got above.
y = 6x - 11
-23 = 6(-2) - 11
-23 = -12 - 11
-23 = -23
CORRECT
So now that we checked our work, and saw that it was correct, I can hereby say that x is -2 and y is -23
x = -2
y = -23
(x, y) --> ( -2, -23)
Hope this helped!!!

PLS HELP ME FAST FREE 16 POINTS Rectangle PQRS is graphed on a coordinate plane with vertices P(–2, 1), Q(–2, 4), R(–4, 4), and S(–4, 1), as shown below.
Rectangle PQRS is reflected over the y–axis and then translated 2 units to the left. What are the coordinates of P'?
O(1, 0)
O(0, 1)
O(4, 1)
O(–4, –1)
Answer:
Pretty sure it's B!
Step-by-step explanation:
Over the Y axis- (2,1)
To the left two times= (0,1)
Hope this helped!
Answer:
(0,1)
Step-by-step explanation:
Since the problem is only asking about P', let's ignore the rest of the rectangle. P's coordinates are to be reflected across the y-axis, putting P' at (2,1). Move P' left by two units and your 'x' is 0, your 'y' is the same. So, (0,1)

Given the system of equations:
2x + 2y = 12
X-y= 2
What is x equal to?
8
4
2
1
-2
Answer:
x=4
y=2
Step-by-step explanation:
2x+2y=12
x−y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+2y=12,x−y=2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+2y=12,2x+2(−1)y=2×2
Simplify.
2x+2y=12,2x−2y=4
Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.
2x−2x+2y+2y=12−4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
2y+2y=12−4
Add 2y to 2y.
4y=12−4
Add 12 to −4.
4y=8
Divide both sides by 4.
y=2
Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2=2
Add 2 to both sides of the equation.
x=4
The system is now solved.
x=4,y=2
Correct choice is B) x=4.
answer is 4
because y=2 then you subsistute it in and then you find X
x-y=2 turns to x=y+2 then you subsistute that into x of the equation 2x+2y=12 which then is 2(y+2)+2y =12 and you should get y=2 then you grab the other equation x-2=2 and you should get x=4
Rafael got 3 boxed candies and 1 bag of chips for $6.99. His sister got 2 bags of chips and 1 boxed candy for $5.98. Find the cost for 1 of each of these items in dollars.
Answer:
Step-by-step explanation:
Let us represent
Boxed candles = x
Bag of chips = y
Rafael got 3 boxed candies and 1 bag of chips for $6.99.
3x + y = 6.99....Equation1
His sister got 2 bags of chips and 1 boxed candy for $5.98.
x + 2y = 5.98......Equation 2
Find the cost for 1 of each of these items in dollars.
Kevin is doing an experiment where he flips a fair coin 20 times and analyzes the results. The coin has come up heads the first 19 trials. What is the conditional probability that the next flip will come up tails, given that the previous 19 flips were heads? Explain why your answer makes sense.
Answer:
it's still 50%
each flip is an independent probability. what happened the first 19 times is irrelevant, because it's still a 50-50 chance on any independent flip.
A study gathers data on the outside temperature during the winter, in degrees Fahrenheit, and the amount of natural gas a household consumes, in cubic feet per day. Call the temperature x and gas consumption y. The house is heated with gas, so x helps explain y. The least-squares regression line is yhat = 1344 – 19x. 1. On a day when the temperature is 20F, the regression line predicts that gas used will be about
Answer:
The answer is "964 cubic-feet".
Step-by-step explanation:
Given regression equation:
[tex]\to Y = 1344 - 19X\\\\\to X= 20 \ F[/tex]
Putting the value of x into the above equation:
[tex]\to Y = 1344-19\times20\\\\[/tex]
[tex]= 1344-380\\\\= 964 \ cubic-feet[/tex]

(101)² solve it using identities
Answer:
10201
Step-by-step explanation:
=(101)²
=(100+1)²
={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]
=10000+200+1
=10201
Solution :-
Given,
(101)^2We need to solve it using identities.
>> (100 + 1)^2
As we know that,
>> (a + b)^2 = a^2 + b^2 + 2ab
Here,
a = 100 b = 1Using the identity we gets,
>> (100)^2 + (1)^2 + 2(100)*(1)
>> 10000 + 1 + 200
>> 10000 + 201
>> 10201

-7 increased by a number n is 12
A: -n - 7 = 12n = -19
B: 12+n = -7n = 7/12
C: -7 + n =12n=19
D: None of the Above
Answer:
It may be C or D
I think its C.
Sorry if I'm wrong.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
let the number be n then increasing - 7 by n is - 7 + n and
- 7 + n = 12 ( add 7 to both sides )
n = 19
triangle ABC is similar to triangle EHG , find the measure of angle EHG .
Answer:
[tex]\angle EHG = 80[/tex]
Step-by-step explanation:
Given
ABC ∼ EHG
See attachment
Required
Determine [tex]\angle EHG[/tex]
First, we calculate x in ABC
[tex]x + 2x + 60= 180[/tex]
[tex]3x + 60= 180[/tex]
[tex]3x = 120[/tex]
[tex]x = 40[/tex]
The corresponding angle to [tex]\angle EHG[/tex] is [tex]\angle ABC[/tex]
and
[tex]\angle ABC = 2x[/tex]
[tex]\angle ABC = 2 * 40[/tex]
[tex]\angle ABC = 80[/tex]
Hence:
[tex]\angle EHG = 80[/tex]
