Use the graph to find the relationship between the two variables. Select all that apply.
The variables are 2 and 7.
The variables are dollars and hours.
Hours is the independent variable and dollars is the dependent variable.
Dollars is the independent variable and hours is the dependent variable.
The relationship is x = 3.50y.
The relationship is y = 3.50x.
By using the graph, all of the true statements that apply include the following:
B. The variables are dollars and hours.
C. Hours is the independent variable and dollars is the dependent variable.
F. The relationship is y = 3.50x.
What is a proportional relationship?In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:
y = kx
Where:
y represents the cost in dollars.x represents the number of hours.k is the constant of proportionality.Next, we would determine the constant of proportionality (k) by using the various data points from table D as follows:
Constant of proportionality, k = y/x
Constant of proportionality, k = 3.5/1 = 7/2 = 10.5/3
Constant of proportionality, k = 3.50
Therefore, the required linear function is given by;
y = kx
y = 3.50x

57. A rectangular room measures 12 1/2 feet by 15 1/3 feet. It is divided into three equal parts.
Calculate the area of one of those parts.
PLEASE HELP QUICK. (WIlL GIVE BRAINLIST) Erina runs 200 meters each day during the first week of her training. She plans to increase the distance she runs each week. Erina's training goal is to run 150% of the distance she ran each day in the previous week. She will run the same distance each day in a week. There are approximately 27.34 yards in 25 meters. If Erina meets her goal, how many yards will Erina run each day in the third week of her training? Round the answer to the nearest hundredth. Enter the answer in the box _____ yards
During the first week of her training, she runs 200 meters. On the second week, she plans to run 50% more.
Now, how do you calculate this?
To increase 200 meters by 50%, multiply by 1.5
The second week she pans to run 450 meters.
Since there are only 3 weeks, do it again!
The thrid week, she plans to run 675 meters.
Since she runs the same ammount each day of the week, the calculation is simple.
7(200) + 7(450) + 7(675)
In these three weeks, she runs 9275 meters.
OR, she runs 10143.26 yards.

For each of the relation sets below, determine the domain and range, along with
whether or not the set represents a function. If the relation set is not a function, explain
why.
a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}
b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}
c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}
d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}
Answer: See in the explanation
Step-by-step explanation:
The domain is all of the X values in a set.
The range is all of the Y values in a set.
You can tell if a set of coordinate pairs is a function if each x value corresponds to 1 Y value. For example, lets say we have an x value of 3. This X value can only correspond to ONE y value. So if the x value 3 corresponded to , e.g, 4, or 7 as y values, it would not be a function because 1 x value has to have only 1 y value.
a. {(0,9), (8, 1), (-1, 9), (9, 8), (1, -1)}
* This relation is a function, because there aren't many of the same x value numbers.
* The domain is {0, 8, -1, 9, 1}. Those are all of the X values
* The range is {9, 1, 9, 8, -1} (All of the Y values)
b. {(62, -3.1), (61, -3.1), (60, -3.1), (-3.1, -3.1)}
* This relation is a function, because even though all of the y values are the same , the x values are different.
* The domain is {62, 61, 60, -3.1}.
* The range is {-3.1, -3.1, -3.1, -3.1}
c. {(123,876), (-15, 2.6), (2.6, -15), (123, 1), (-87, -0.98)}
* This relation is a function, because all of the X values are different
* The domain is {123,876, -15, 2.6, 123, -87}
* The range is {0, 2.6, -15, 1, -0.98}
d. {(2.9, 0), (2.9, 1), (2.9, 2), (2.9, 3)}
* This relation is not a function. All of the x values are the same, and for this reason, they all have different y values.
* The domain is {2.9, 2.9, 2.9, 2.9}
* The range is {0, 1, 2, 3}

What is the area, in square meters, of the trapezoid below?
Answer: 94.54 m^2 (square meters)
Step-by-step explanation: The formula for the area of a trapezoid is A = 1/2(a+b)h; where a and b are the two top sides of the trapezoid that are parallel. Let us then solve.
Let us combine both sides two maintain the overall side for "b", which is 18 + 5.1 = 23.1
Let us now add both sides (a + b.) 23.1 + 9.5 is 32.6. We can now multiply by the height. 32.6 multiplied by 5.8 is 189.08
We can now divide (or multiply by 1/2), which is 189.08 * 1/2 or 189.08/2 and that equals 94.54.
Step 1
Find the area of the Rectangle in the middle
To find the area, you have to do [tex]Length*Width[/tex]
[tex]9.5*5.8=55.1[/tex]
The area of the Rectangle in the middle is 55.1m²
Step 2
Find the area of the triangle on the right
To find the area of 1 triangle, we have to use the formula show below:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
[tex]A=\frac{1}{2} *5.1*5.8\\=\frac{1}{2} *29.58\\=14.79[/tex]
The area of the triangle on the right is 14.79m²
Step 3
Find the area of the triangle on the left
Using the formula that we used in the last question about finding the area of the triangle, we can find our answer, here is the formula:
[tex]A=\frac{1}{2}* Base *Height[/tex]
Base = the part on the bottom
Height = How high the triangle is
BUT, before finding the area of this part of the triangle, we have to first find the dimensions, we know the height, but we don't know the base, so to find the base, we will subtract 18 by 9.5 to get our base
[tex]18-9.5=8.5[/tex]
So the base of the triangle on the LEFT is 8.5m
NOW, we can find the area of the triangle on the left
[tex]A =\frac{1}{2}* 8.5*5.8\\=\frac{1}{2} *49.3\\=24.65[/tex]
So the area of the triangle on the LEFT is 24.65m²
Step 4
Add up all the areas to get final answer!
The areas of the 3 shapes are...
55.1m²
14.79m²
24.65m²
If we add these numbers up, we get 94.54m²The area of the trapezoid is 94.54m²

Answer:
1005.3 [tex]ft^{3}[/tex]
Step-by-step explanation:
V=π r^2 h = π · 42· 20 ≈ 1005.30965 ---> 1005.3
Answer:
the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.
So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.
Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.

A tank can be filled in 22 and a fifth minutes. What fraction of it will be filled in 21 min
Answer:
I believe the answer is about 95 percent.
Step-by-step explanation:
The reason for this answer is because as said 22 and a fifth would mean the tank is full. This means I set up a proportion. What I did was...
22 1/5 over 100 = 21 over x
Now: I do 21 multiply by 100 divided by 22 1/5 to get the answer
What I just wrote is the rule of proportions
Finally, after doing all of that, the answer I got was 94.59459459, but I rounded to the answer of 92 percent.

Vera claimed the solution set on the number line represents the inequality Negative 78.9999 greater-than-or-equal-to x.
A number line going from negative 83 to negative 77. A closed circle is at negative 79. Everything to the left of the circle is shaded.
Which error did Vera make?
Vera wrote the inequality with the variable on the left side of the relation symbol.
Vera wrote a relation symbol that does not represent the direction of the ray.
Vera selected an inequality that does not include –79 in its solution set.
Vera used the wrong number in her inequality.
So basically, we have [-83, -77] as the whole thing.
There's a circle that limits [-83, -79) as a shaded zone.
Vera claims that -78.9999 [tex]\geq[/tex] X, which is false.
Vera wrote a relation symbol that doesn't represent the ray's direction. She went the other way around.

Answer:
m = 8
Step-by-step explanation:
turn it into a square and then you can divide 48 by 6 and the answer is 8
Answer:
the answer for the first one is 8 because we need to divide the area which is 48 by 6 to get the answer which is 8 so we multiply 6 times 8 to check if it is 48 and yes sir it is.
In the second one you need to divide 42 by 6 not by 4 and when you do that you get 7 so we multiplied 6 times 7 to check if the area is 42 and yes it is sir again so the first one is 8 and the second one is 7
