Answer:
I think the answer is $798
Step-by-step explanation:
143×2=286
200×2=400
56×2=112
286+400+112=$798
They earned $798
The first thing you have to do in order to find your answer is add up the total amount of candy bars sold for the total 3 days. Then once you have that added up, multiply it by 2 (since they were worth 2 dollars each) and you will come up with $798 total.

Find the constant of proportionality for each graph. Write your answer as y-kx.
Answer:
1. y=5x
2. y=9x
3.y=2x
4.y=3x
Does the equation y=3x+4 show a proportional relationship between x and y?
1.Yes, the graph of the equation is a straight line and passes through the origin.
2.No, the graph of the equation is not a straight line.
3.No, the graph of the equation does not pass through the origin.
4.Yes, the graph of the equation is a straight line.
Simplifying
y = 3x + 4
Reorder the terms:
y = 4 + 3x
Solving
y = 4 + 3x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 4 + 3x
Answer:
3. No, the graph of the equation does not pass through the origin. (0,0)

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.
1. The slope of the linear model is 1.5. What does this mean in terms of the maximum noise level and the number of people?
2. A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.
3. What is the -intercept of the linear model given? What does it mean in the context of the problem? Is this reasonable? Explain your reasoning.

Answer:
A. <dilation by a factor of 1/7>
Step-by-step explanation:
Rotation, reflection, and translation are "rigid" motions that preserve congruence.
Dilation does not preserve congruence. Dilation multiplies the coordinates by a dilation factor, as in the transformation of choice A.
(x, y) ⇒ (x/7, y/7) . . . does NOT preserve congruence

Find the number of revolutions made by a wheel with a radius of 5 ft that traveled 633 ft. Use 3.14 for pi. Round your answer to the nearest tenth of a revolution.
A)40.3 revolutions
B)8.1 revolutions
C)19,876.2 revolutions
D)20.2 revolutions
Answer:
d
Step-by-step explanation:
1) convert ft to cm
5ft=152.4cm
633ft=19293.84cm
2) 2*3.14*152.4=975.072
3)19293.84/975.072 = 20.16rev
1. Thad bought 8 notebooks that cost $3.79 each. If he gave the cashier a $50 bill, how much change did he get back from the purchase?
2.Lucy purchases a car for $16,314.40. If she makes a payment each month for the next 40 months, how much will she pay each month. (enter your answer as $dollars.cents)
Answer:
Step-by-step explanation:
1. Cost of each notebook = 3.79
Cost of 8 notebooks = 3.79 x 8 = 30.32
Amount gave to cashier = 50
Change = 50 - 30.32 = 19.68

An infant playpen is in the shape of a circle. If the playpen has a radius of 2, what is the approximate area of the playpen? Use 3.14 for pi.
a 12.56 square meters
b 6.28 square meters
c 3.14 square meters
d 10.14 square meters
Answer:
The answer is 12.566 or 12.57
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi[/tex]r²
∴ 3.14×(2)² is equal to 12.566 or 12.57
Determine the measures of the unknown angles in the figure.
m < APD =
m < CPE =
m < BPD =
Answer:
angle APD=115 degrees
angle CPE=25 degrees
angle BPD=65 degrees
Step-by-step explanation:
APD=180-65=115 because it is supplementary
CPE=90-65=25 because it is complementary
BPD=65 because it is an alternate angle
The measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.
What is an angle?An angle is a geometrical shape that is formed by two rays or lines, called the sides or arms of the angle, that share a common endpoint, called the vertex of the angle.
Given is a figure, we need to find the measurement of the asked angles,
m ∠APD, m ∠CPE and m ∠BPD.
So,
∠APD + ∠APC = 180° [linear pair]
∠APD = 180° - 65°
∠APD = 115°
∠CPE + ∠CPA = 90° [complimentary angles]
∠CPE = 90° - ∠CPA
∠CPE = 90° - 65°
∠CPE = 25°
∠BPD = ∠APC [vertical angles]
∠BPD = 65°
Hence, the measurements of the asked angles are m ∠APD = 115°, m ∠CPE = 25° and m ∠BPD = 65°.

12) Jennifer earns $78 per day working at a supermarket. She spends $8 each day at lunch and her gas to get to and from work is $6 per day. How much money will she earn in 28 days?
Answer:
$1792
Step-by-step explanation:
$78 x 28 = 2184
28 x $8 = 224
28 x $6 = 168
168 + 224 = 392
2184 - 392 = $1792
Check Work:
1792 + 392 = 2184
2184 / 78 or 2184 / 28
=78

Groundhog's Day is on February 2nd each year. On this day, in Punxsatawney, Pennsylvania, thousands of onlookers watch to see if Phil, the groundhog, will cast a shadow. If he does, then six more weeks of winter are predicted. If he doesn't, then an early spring is predicted. Historically, Phil's prediction has only been correct about 40% of the time.
Using complete sentences, design a simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years. Make sure to explain how you would use the simulation to determine the probability.
A simulation to determine the probability that Phil's prediction will be correct at least two out of the next three years is given as follows:
Choose three numbers with replacement from the set of 0 to 9, which:
numbers from 0 to 3 representing that Phil is correct.numbers from 4 to 9 represents that Phil is incorrect.How to calculate a probability?The parameters that are needed to calculate a probability are given as follows:
Number of desired outcomes in the context of a problem/experiment.Number of total outcomes in the context of a problem/experiment.Then the probability is calculated as the division of the number of desired outcomes by the number of total outcomes.
The probability of a success on a single trial is given as follows:
40% = 0.4, as Phil is correct 40% of the time.
Hence the simulation needs to have three trials, each with a 0.4 = 40% probability of a success.
