Step-by-step explanation:
“Suppose we covered a large section of wall with chalkboard paint.
How would we find the area we wanted to paint?” Your student might
answer, “Measure how high and how far across, then multiply.” Then
ask, “If one quart of paint covers 65 square feet of wall, how many
quarts would we need to paint the blackboard section with 2 coats?”
Your student would multiply the area by 2 and compare that number
to 65. For example, a blackboard 8 feet wide and 5 feet high is
40 square feet, and 2 coats would be 80 square feet. One can of
paint would not be enough.
• “Suppose we put new carpet in your bedroom. How many square feet
would we need to buy? How would we figure this out?” Your student
might answer, “Measure each wall of the room and multiply. If the
room isn’t a perfect rectangle, divide it into smaller pieces that are
easier to work with.”
Getting your student involved with home projects develops useful skills for
helping around the house, finding a part-time job, and eventually being
responsible for his or her own home.

The function A(t) = 1950 (0.65)t models the amount A(t) , in dollars, that Ted's company deducts from his check for health insurance based on time t, in months that Ted has worked for the company. Determine the rate used in this formula and identify as growth or decay.
Answers
Answer:
This is an Exponential decay
The Exponential decay rate = 35%
Step-by-step explanation:
Looking at that the above question, it is an Exponential decay
The formula for Exponential decay is:
A(t) = Ao (1 - r)^t
In the above question:.
A(t) = 1950 (0.65)^t
r = rate
Hence:
(1 - r) = (0.65)
1 - r = 0.65
r = 1 - 0.65
r = 0.35
Converting to percentage
0.35 × 100
= 35%
Hence, the Exponential decay rate is 35%

Add a construction job for a gallery there are 20 painters of those painters 11 of them are painting interior of the gallery what percent of these painters are painting the interior
Answers
Answer:
55%Step-by-step explanation:
Given
Total number of painters = 20
Number of painters painting the interior = 11
Percentage of those painting the interior = painters painting the interior/Total painters * 100
Percentage of those painting the interior = 11/20 * 100
Percentage of those painting the interior = 11 * 5
Percentage of those painting the interior = 55%
Hence the percent of those painters painting the interior is 55%

10 = A
9 = B
8 = C
so from smallest to largest the angles are C, B, A

Answers
Answer:
point form (-8,40)
equation form x=-8, y=40
Step-by-step explanation:
Answer:
(- 8, 40 )
Step-by-step explanation:
Given the 2 equations
2x + y = 24 → (1)
3x + y = 16 → (2)
Subtract (1) from (2) term by term to eliminate the y- ter, that is
x = - 8
Substitute x = - 8 into either of the 2 equations and solve for y
Substituting into (1)
2(- 8) + y = 24
- 16 + y = 24 ( add 16 to both sides )
y = 40
solution is (- 8, 40 )

360 degrees divided among 12 identical angles is 360/12 = 30 degrees
A microscope was originally priced at $148.48, but Krysta waited to buy it until the microscope was on sale for 25% off. If she paid 6.25% sales tax on the sale price, how much did she pay in total?
Answers
Answer:
$120.64
Step-by-step explanation:
Step one:'
given data
originally price fo microscope = $148.48
discount= 25%
tax= 6.25%
Step two:
the total amount paid for the microscope
1. Amount of the discount= 25/100*148.48
= 0.25*148.48
=$37.12
2. Amount of tax
= 6.25/100*148.48
= 0.0625*148.48
=$9.28
Step three:
The total amount is
= 148.48-37.12+9.28
=$120.64

1.I will solve your system by substitution.
−x+2y=6;6y=x+18
Step: Solve−x+2y=6for x:
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
[tex]\frac{-x}{-1} =\frac{-2y}{-1}[/tex] Divide by -1
x=2y−6\
Well I did this problem differently I substitute
Step: Substitute2y−6for x in6y=x+18:
6y=x+18
6y=2y−6+18
6y=2y+12
6y+−2y=2y+12+−2y
4y=12
[tex]\frac{4y}{4} =\frac{12}{4}[/tex]
y=3
Step: Substitute3 for y in x=2y−6:
x=2y−6
x=(2)(3)−6
x=0
Your final answer will be x=0 and y=3
