Use the graph to determine the constant of proportionality between the number of miles traveled and the number of hours traveled.
A. 60
B. 65
C. 130
D. 585
Answer: B. 65
Step-by-step explanation:
Choose any point on the number line with natural numbers for both coordinates. For this case, let's use (4, 260).
To find the constant of proportionality, divide the Y coordinate by the X coordinate. 260 ÷ 4 = 65. While optional, it is reccomended to use two points to confirm your answer. Let's do that with (2, 130). Since 130 ÷ 2 = 65, this confirms that the constant of proportionality is 65.

Answer:
y = x + 2.5
Step-by-step explanation:
slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points
slope = (2.5-1.5)/(0+1) = 1
equation = y-y1 = m(x-x1)
y - 2.5 = x
y = x + 2.5

If the measure of \angle∠4 is 68 degrees,, find the measure of \angle2∠2 in degrees.
Hi, there! I'd love to help you out!
We know complementary angles add up to 90 degrees.
Let's say our first angle is x:
x = first angle
It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:
x = first angle
x + 68 = second angle
Now add the two and set it equal to 90 degrees:
x + x + 68 = 90
2x + 68 = 90
-68 -68
2x = 22
/2 /2
x = 11 first angle
x + 68 = 11 +68 = 79 degrees second angle

Answer:
Quadratic function, None of the above, and ?
Step-by-step explanation:
So remember what I told you about earlier, lets look at that first one.
So we can see that x is increasing by 1 and y is decreasing by 3...And then it increases by 3! And after that another 9! Well, that seems like it is reversing, as it changes from decreasing to increasing in y coordinates. So knowing that is reverses from decreasing to increasing in y, it must be a quadratic function!
Next we have a increase in 1 and a decrease by 17...then 12...then 7 in y. This isnt decreasing by a constant amount like a linear function. It doesnt seem like a obvious exponential decrease either, and it isnt reversing like a quadratic function does. I am going to use something called logarthms, which you don't even need to think about yet, just to make sure that it is not an exponent. Althouhg the difference in the exponent was only 0.0018, it is a differnece. So this must be a none of the above, sicne none of the functions apply. (If this is incorrect, and it is exponential, then the test is wrong. While the method I used is something found in mid algebra 2, it is still a method of finding a exponent of a number.)
Now we finish up with a change in x of 1, and a change of y by...-11, -11, -11!
Well, what do you think this is, thinking back on what I have said so far.
It is a constant change of -11y and 1x. Remember, a CONSTANT CHANGE.
What do you think it is :)
If you cannot figure it out, let me know in comments.
Hope this is helps you!

Answer:
We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.
Since it takes Angel 2 minutes to run 1 lap, she will take
2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.
So it takes Angel 5 minutes to run 1 km.
Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden
2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.
So it takes Jayden 416 minutes to run 1 km.

Answer:
Step-by-step explanation:
Distance traveled in 2 minutes by Angel = 2/5 kilo meter
Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2
[tex]=\frac{2}{5}*\frac{1}{2}[/tex]

Number of Students

Would a dot plot or a histogram best represent the data presented here? Why?
-------------------------
Here are the answer choices:
A: Dot plot, because a large number of scores are reported as ranges
B: Dot plot, because a small number of scores are reported individually
C: Histogram, because a large number of scores are reported as ranges
D: Histogram, because a small number of scores are reported individually
Answer:
A dot plot generally shows the data for a specific value, it is just like how you would need each individual's score. A histogram shows data for a range of values. The best one to use here is a histogram.
Step-by-step explanation:
Answer: The answer is C
Step-by-step explanation: Histograms show ranges and the table shows ranges and scores. A dot plot would not fi this situation as well as histograms because histograms are best when it comes to ranges.

Step-by-step explanation:
The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.
Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.
Solve the equation `r(w)=30`and explain what the solution means in this situation.
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
please mark as brainliest
Answer:
w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.
Step-by-step explanation:
r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.
75-4.5w=30
75-75-4.5w=30-75
-4.5w=-45
-4.5w/-4.5 = -45/ -4.5
w=10

Find the volume...!!!
Answer:
volume = 143.1 m^3
Step-by-step explanation:
here's your solution
=> volume of cuboid = area of base * height
=> volume = 53*2.7
=> volume = 143.1 m^3
hope it helps
Answer is below. Look at the explanation to understand my answer.
To find the volume, you simply multiply all the lengths up to get your answer.
The formula is for finding the volume of a rectangular prism is: L × W × H. Normally there is 3 lengths, but there is only 2. We can still solve by using the same formula, instead of L × W × H, the formula will be Base Area × Height or BA × H.
Here is a breakdown: Solving for a Cuboid (rectangular prism) is easy; all you need to do is multiply all the units.
With that being said...
53 times 2.7 is 143.1 m²
Therefore, 143.1 is the volume
Let me know of questions or concerns about my answer.
Formulas:
V = L × W × H (Length × Width × Height)
V = BA × H (Base Area × Height)
This One Is Easy! :)
