Answer:
[tex]\frac{1039}{238}[/tex]
Step-by-step explanation:
7x + 1039 = 245x
Minus the smallest x from the largest.
1039 = 245x - 7x
1039 = 238x
Divide 1039 by 238x to find the x
[tex]\frac{1039}{238}[/tex] = x
Write an equation representing the relationship of 10:20 shown in the graph
Answer:
[tex]20=2(10)[/tex]
Step-by-step explanation:
10:20 is a good point that passes a line to another.
This graph is a linear graph.
The linear equation is
[tex]y=mx+b[/tex]
[tex]y[/tex] = 20 (the y coordinate in the graph)
[tex]m[/tex] = slope
[tex]x[/tex] = 10 (the x coordinate in the graph)
[tex]b[/tex] = y-intercept
Finding slope
To find the equation, we'll need to plug in the values in the formula. To find slope using two points, use the formula, then plug in the values:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
(10, 20) and (20, 40)
[tex]=\frac{40-20}{20-10}[/tex]
[tex]= \frac{20}{10}[/tex]
[tex]\bold{m= 2}[/tex]
Finding the y-intercept
You have to find the slope first before finding the y-intercept. So, plugin one of the two points we used to find the slope into the formula and solve for [tex]b[/tex]
(10, 20)
[tex]20=2(10)+b[/tex]
[tex]20=20+b[/tex]
[tex]20-20=20-20+b[/tex]
[tex]\bold{b=0}[/tex]
The y-intercept is zero, and when it is, you do not add it since zero is nothing.
The equation is [tex]20=2(10)[/tex]

• At store A, 3 pounds of apples cost $12.
• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
• The cost of apples at store C is shown in the graph.
(don't worry about the graph I know how to do this one)
Answer the questions to find out which store's apples are the least expensive.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.
Is using the associative property of addition a good strategy for simplifying (4/3 + 2/3) + 2? Why or why not?
Answer:
Easy way
Step-by-step explanation:
(4/3 + 2/3) + 2
= 2 + 2
=4
Oviously (4/3 + 2/3) is directly 2.

When astronauts Neil Armstrong and Buzz Aldrin first walked on
the moon in 1969, they were able to bounce from step to step!
This is because the gravitational force of the moon is about
16.5% of that of the Earth. If you visited the moon,
weighing 100 pounds on Earth, what would your weight be?
Answer:
16.5 pounds
Step-by-step explanation:
16.5% as a decimal is 0.165
0.165 x 100 = 16.5
So in conclusion you will weigh about 16.5 pounds on the moon.
Shaun is painting a fence. After finishing three-eighths of the length of the fence he finds that
he has painted 15 feet. Let f be the total length of the fence, set up an equation like one of
those in 4(b) and solve to find f. Use either of the two methods.
Answer: F = 40
Step-by-step explanation:
*Important: I do not know what the methods mentioned in 4b are, nor do I know its equation. Please take this into account.
What we know:
3/8 is equal to 15 ftF is the total amount of fence paintedWe need to set up and solve the equationHow we do this:
Using basic division, this equation is solveable.
Process:
Divide to find 1/8 15/3 = 5 (1/8f = 5)Multiply to find total 5 x 8 = 40(1/8 x 8 = 8/8)
Solution:
F = 40
8(5) = F
Answer: x = 40
Step-by-step explanation:
let f be the total length of the fence:
(3/8)f = 15
divide both sides by 3/8
f = 15 x 8/3
f = 120/3
f = 40

A tire from Karens car is shown below Which is closest to the distance traveled, in feet, after 3 full rotations of the tire? use pi= 22/7
Answer:
264 inches
Step-by-step explanation:
Circumference = pi x diameter
28 x 22/7 = 88 (in)
88 x 3 = 264 (in)
The closest distance traveled by Karen's car is, 18.86 feet.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We know that;
One rotation of the tire is equal to the circumference of the tire.
And, The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where, π = 22/7
d = diameter
Here, The size of one revolution = 2 x 22/7
= 44/7 feet
Hence, The distance covered in one rotation of the tire is 44/7 feet
So, The distance covered in 3 rotations = (44/7) x 3

A special piece of equipment is used at a construction site to dig holes. A hole is dug to a depth of 3.25 feet when the equipment hits rock. The progress slows to 5/8 feet per hour of digging. The depth of the hole must be at least 11 1/2 feet by the end of the day to stay on schedule. What is the minimum amount of time the equipment must continue at its present rate to complete the hole on schedule?
Select from the drop-down menus to correctly complete the statement.
The equipment requires at least 13 or 23 hours and 2/6/12/36 minutes to complete the hole on schedule.
Answer:
13 hours and 12 minutes
Step-by-step explanation:
You put 3.25 as a fraction which is 3 1/4. then I took 3 1/4 and misused it by 11 1/2. 23/2 - 13/4 = 8 1/4 then we took the 5/8 and divided it by 33/4 (3 1/4) I got 13 1/5. 13 1/5 is 13 hours and 12 minutes.
Minimum amount of time taken to complete the hole is 13 hours and 12 minutes.
What is proportion?In mathematics, proportion is an equation where two ratios are taken to be equal to each other. Suppose if a:b = c:d, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex].
In the question, it is given that, a hole is already dug to a depth of 3.25 feet = 3 [tex]\frac{1}{4}[/tex] feet.
Also, the depth of hole at the end of the day must be atleast 11 [tex]\frac{1}{2}[/tex] feet.
Remaining depth of the hole needed to dug = 11 [tex]\frac{1}{2}[/tex] - 3 [tex]\frac{1}{4}[/tex] = [tex]\frac{23}{2}[/tex] - [tex]\frac{13}{4}[/tex] = [tex]\frac{33}{4}[/tex] feet
Rate of digging is [tex]\frac{5}{8}[/tex] feet per hour.
We have to find how much time will be taken for [tex]\frac{33}{4}[/tex] feet.
In proportional form, it can be written as [tex]\frac{5}{8}[/tex] : 1 = [tex]\frac{33}{4}[/tex] : x, where x is the time taken to complete [tex]\frac{33}{4}[/tex] feet.
⇒ [tex]\frac{5}{8}[/tex] / 1 = [tex]\frac{33}{4}[/tex] / x
Cross multiplying, we get
[tex]\frac{5}{8}[/tex] × x = [tex]\frac{33}{4}[/tex] × 1
⇒ x = [tex]\frac{33}{4}[/tex] × [tex]\frac{8}{5}[/tex] = [tex]\frac{66}{5}[/tex] = 13 [tex]\frac{1}{5}[/tex]
Hence the minimum amount of time the equipment must continue at the present rate to complete the hole on schedule is 13 hours and 12 minutes.

Hi!
It seems like you have two answers in the boxes already, but it is not correct.
Firstly, you cannot tell mean from a box plot. The first box should be moved to the last category.
Your second boxes seems to be correct though.
As far as the remaining boxes, I can help with those too!
Median: The median is identifiable in a box plot, as the line in the boxes themselves are the medians. The medians do line up, therefore they belong in category 1.
Minimum: This is the value that is the least. We can tell this from a box plot, by looking at the most left line, or the "whiskers", as some teachers call them. For our box plots, the minimum is 4. They line up exactly. Therefore, this box should go in the first category.
IQR: The IQR "measures the spread of the middle half of your data". In these box plots, the IQR is different. Therefore, it belongs in the second category.
Mode: This is the value that appears most often in a set of data values. You cannot tell this from a box plot. Therefore, it belongs in the last category.
