Answer:
According to the table, you had $50 in savings at the beginning, during Week 0.
Find the selling price. Round to the nearest cent for each 18-20
18. cost: $10 percent markup: 50%
19. cost: $28 percent markup: 25%
20. cost: $65 percent markup: 70%
Answer:
18: 15$
19: 35$
20: 110.50$
Step-by-step explanation:
18: A 50% markup would mean 5 dollars extra which makes it 15$
19: 25% of 28 would be an extra 7 dollars which makes it 35$
20: 70% of 65 would be 45.50 cents, adding this to 65 would make it 110.50$
Future help with percentages: When an item is marked up it would mean the percentage is multiplied by the initial value and then add the product with the initial value.

A group of students was asked about the number of flights they have taken. The data is shown in the line plot.
A line plot titled Flights Taken. The horizontal line begins at 3, with each unit marked up to 14. There is one dot above 6, 9, 10, and 11. There are two dots above 5, 7, and 8.
Which of the following best describes the spread of the data? Explain its meaning in this situation.
The data has a range of 11, which is a wide spread. This means that one student had 11 fewer flights than the students with the most number recorded.
The data has a range of 6, which is a narrow spread. This means that there is not a large difference in the number of flights taken by the students.
The data has a range of 11, which is a narrow spread. This means that there is about the same number of flights taken by each of the students.
The data has a range of 6, which is a wide spread. This means that there is a difference of 6 flights between each of the students.
The data has a range of 11, which is a wide spread. This means that there is a large difference in the number of flights taken by the students, with one student having taken 11 more flights than the student who took the least number of flights recorded. In this situation, the spread of the data indicates that some students have taken significantly more flights than others.
The data has a range of 6, which is a wide spread. This means that there is a difference of 6 flights between each of the students.
How to obtain the range of a data-set?The difference between the highest and lowest values in a data collection indicates the range of that data set.
The dot plot displays the frequency of each amount observed, so:
The lowest number is of 5.
The highest number if of 11.
Then. the range is
=11 - 5
= 6.

Part I: Making the Race
Henri is Emile's younger brother and they are having a walking race. Emile can walk 2.5 meters per second whereas Henri walks 1 meter per second. Because Emile is faster, they give Henri a 45 meter head start. Emile knows Henri would enjoy winning the race, but they do not want to make the race so short that it is obvious Emile let Henri win.
1. How long should the race be so that Henri will win in a close race?
2. Describe or show your strategy on how you came up with your answer for #1.
74 meters
Step-by-step explanation:
The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.
2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.
6.5/40.3 = M/12.4 what dose m =
m=2
[tex] \frac{6.5}{40.3} = \frac{m}{12.4} [/tex]
[tex]40.3m \: = 6.5 \times 12.4[/tex]
[tex]m = \frac{6.5 \times 12.4}{40.3} [/tex]
[tex]m = \frac{80.6}{40.3} [/tex]
[tex]m = 2[/tex]
Answer:
M = 2
Step-by-step explanation:
What does it mean to have something be equal (Equivalent)?
Equivalence means to be same, whether it be value, temperature, size, etc.
If equivalence means to be the same, we can use this equation to figure out what M is equal to.
40.3 ÷ 12.4 = 3.25So, in order to solve for M, we need to divide 6.5 by 3.25.
6.5 ÷ 3.25 = 2Therefore, M = 2.

The amount y (in cups) of flour is proportional to the number x of eggs in a recipe. The recipe calls for 4 cups of flour for every 2 eggs. A. Write an equation that represents the situation. B. Interpret the slope. C. How many cups of flour would you need for 8 eggs?
Answer:
A. y = 2x + 0 B. The slope of the equation is 2, which means that for every 2 eggs, you need 4 cups of flour. C. For 8 eggs, you would need 16 cups of flour.
Answer: 16 cups of flour
Step-by-step explanation:
As amount of flour is directly proportional to number of eggs,
2/4 = 8/y
y = 8*4/2 = 16

two quadrilaterals that have matching angles but different side lengths.
Answer:
Step-by-step explanation:
ere are two quadrilaterals that have matching angles but different side lengths:
1.Quadrilateral ABCD:
Angle A = 90 degrees, Angle B = 60 degrees, Angle C = 120 degrees, Angle D = 90 degrees
Side AB = 5 units, Side BC = 10 units, Side CD = 5 units, Side DA = 10 units
2.Quadrilateral PQRS:
Angle P = 90 degrees, Angle Q = 60 degrees, Angle R = 120 degrees, Angle S = 90 degrees
Side PQ = 3 units, Side QR = 6 units, Side RS = 3 units, Side SP = 6 units
Both of these quadrilaterals have the same angle measures (90 degrees, 60 degrees, and 120 degrees) but different side lengths. Therefore, they are similar but not congruent.

A mathematics teacher wanted to see the correlation between test scores and homework. The homework grade (x) and test grade (y) are given in the accompanying table. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest tenth. Using this equation, estimate the homework grade, to the nearest integer, for a student with a test grade of 31.
Homework Grade (x) Test Grade (y)
58 52
75 66
66 68
85 74
52 38
74 65
78 76
The linear regression equation that represents this set of data is given as follows:
y = 1.05x - 10.43.
The estimated homework grade for a student with a test grade of 31 is given as follows:
39.46.
How to find the equation of linear regression?To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.
The points for this problem are given as follows:
(58, 52), (75, 66), (66, 68), (85, 74), (53, 38), (74, 65), (78, 76).
Inserting these points into a calculator, the equation is given as follows:
y = 1.05x - 10.43.
The estimated homework grade for a student with a test grade of 31 is x when y = 31, hence:
31 = 1.05x - 10.43
x = 41.43/1.05
x = 39.46.

What is the value of x in this triangle?
Enter your answer in the box.
x =
Answer:
x = 47
Step-by-step explanation:
We need to solve for the interior angle measure x. To get x, we know that the sum of the triangles angle measures are 180, so lets write an equation to find x.
[tex]x+102+31=180[/tex]
Add like terms
[tex]x+133=180[/tex]
Subtract 133 on both sides
[tex]x=47[/tex]
To check our work, we can add the angle measures together so we know we got it right.
[tex]47+102+31=180[/tex]
Answer:
x=48
Step-by-step explanation:
add 102 and 31 then subtract it by 180

152 grams of zinc
Step-by-step explanation:
You can always first create some ratios to clean it up

x being zinc, what we need to find
Next we can cross multiply

[tex]19x = 2888[/tex]
Lastly, we will divide both sides by 19 to get X alone.

Step-by-step explanation:
Since 2 is x and 0 is y, you would put those numbers in the equation. These 2 numbers work for both equations so it is the correct answer.
Answer: Option 2 - (2,0)
Step-by-step explanation:
By substituting the values of x and y only option 2 is appropriate for the equation to be true.
A line contains the point (2, 5) and has a slope of −4.
What is the equation of the line in slope-intercept form?
Enter your answer by filling in the boxes.
y = __ x +__
Answer:
y = -4x + 13
Step-by-step explanation:
y = mx + b
We need the slope (m) which was given to us: -4
We need to find the y-intercept (b)
We will use the point given (2,5) and the slope to find b.
y = 5 from the point (2,5)
x = 2 from the point (2,5)
m = -4 given
substitute these into the equation
y =mx + b
5 = (-4)2 + b
5 = -8 + b Add 8 to both sides
5 + 8 = -8 + 8 + b
13 = b
We now know that m is -4 and b is 13. Write the equation
y = mx + b
y = -4x + 13
