1) The Boateng family has a sickening house whose layout is shown
above. They would like to renovate just bedrooms #2 and 3. Because you
are a contractor, you receive 20% off from Home Depot whenever you
make any purchases. If Home Depot sells your client's ideal wool carpet
for $8.99 per square foot, how much will it cost to carpet both
bedrooms? (Keep in mind that 10'8" would be written as a decimal
approximation of 10.67 ft. Think about why this is.)
a) How many total square feet of carpeting will you need?
Answer:
The cost will be $1662.136
The total square ft of carpeting will be 231.1122ft^2
Step-by-step explanation:
For the bedrooms, the dimension from the image is shown as(see attahced)
Bedroom #2= 10"8' x10"4'
Bedroom #3= 10"8' x11"4'
let us convert all dimension to feet and solve for the area of the bedrooms
Bedroom #2= 10"8' x10"4'
Bedroom #2=10.67x10.33feet
Area of Bedroom #2= 110.2211ft^2
Bedroom #3 = 10"8' x11"4'
Bedroom #3 =10.67x11.33feet
Area of Bedroom #3= 120.8911ft^2
The total area of both rooms is
Total area=110.2211+120.8911
Total area=231.1122ft^2
now the cost of one square floor s $8.99
hence the cost of 231.1122ft^2 will be
Cost of carpet = 231.1122*8.99
Cost of carpet = $2,077.67
Given that, because you are a contractor, you will receive 20% off
therefore it will cost
= (20/100)*2,077.67
=0.2*2,077.67
=$415.534
The cost will now be $2,077.67-$415.534
= $1662.136

All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.
Answer:
4) 120°
5) 20°
6) 55°
Step-by-step explanation:
4) 180°-60°=120°
5) 180°-160°=20°
6) 90°+35 = 125°
180°-125°=55°

Solve the system below by substitution.
6x - y = - 23
2x + 5y = -13
Answer:
x= -4 y= -1
Step-by-step explanation:
6x - y = - 23
-y=-23-6x
y=6x+23, use this to plug in for y in the second equation.
2x + 5y = -13
2x + 5(6x+23) = -13
2x+30x+115=-13
x= -4, use this to plug in for x in the first equation.
6x - y = - 23
6(-4)-y=-23
-24-y=-23
-y=-23+24
-y=1
y= -1
The values after solving the equations by substitution is that the value of x is -4 and the value of y is -1.
What is an arithmetic operation?The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.
As per the provided data in the question,
6x - y = -23 (i)
2x + 5y = -13 (ii)
Multiply equation (ii) by 3
6x + 15y = -39 (iii)
Solve equation (i) and (iii)
-16y = 16
y = -1
Substitute y = -1 in equation (i)
6x = -23 - 1
x = -4.

Answer:
2 and 3
Step-by-step explanation:
Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.
Answer:
60 Degrees
Step-by-step explanation:
Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer
[tex]\frac{180}{3} =60[/tex]
Small and large angle are 60° and 120°.
Given that;
Angles are supplementary
Computation:
Assume;
Smaller angle = a
So,
Large angle = 2a
So,
In supplementary
a + b = 180
a + 2a = 180
3a = 180
a = 60
Smaller angle = 60°
Large angle = 2(60)
Large angle = 180°

calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=17/20D=
The given equation is: E=17/20 D , where E=amount of Euros and D= amount of U.S dollar.
Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get.........
E=17/20(1)
E=1/20=0.85
0.85 Euros have the same amount as 1 U.S dollar.

0.1 + 0.2x +0.3 + 0.05x = -2.4
Answer:
x = -11.2
Step-by-step explanation:
0.1 + 0.2x + 0.3 + 0.05x = -2.4
Combine like terms on the left side.
0.25x + 0.4 = -2.4
Subtract 0.4 from both sides.
0.25x = -2.8
Divide both sides by 0.25.
x = -11.2
Polynomials are not always closed under which operation?
A)Addition
B)Subtraction
C)Multiplication
D)Division
Answer:
D
Step-by-step explanation:
Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater
sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?
Answer:
250
Step-by-step explanation:
x is adult tix, y is senior tix
9x + 6y = $4974
x+y= 636
x=636-y
9(636-y) +6y = 4974
5724 - 9y + 6y = 4974
-3y = 4974-5724
