does the data in the table show a proportional relationship?
Answers
Answer:
Yes.I divided 22.5 by 3, and got 7.522.5/3=7.5
I then added 7.5 from 22.522.5+7.5,
and I got 30.Once I got into the bigger numbers, I just multiplied 7.5 by the last number7x7.5= 52.5
All the numbers were constantly added by 7.5, so
the table is a proportional relationship.I hope this helped! +*♡

Use scientific notation to estimate the number of inches in 1,225 miles. Include all calculations in your final answer. 1 inch =1578x 10-5 miles
Answers
Answer: (7.129)*10^(7) inches.
Step-by-step explanation:
We know that:
1 inch = 1.578*10^(-5) miles.
If we divide both sides by 1.578*10^(-5), we get:
(1/1.578*10^(-5)) inches = 1 mile
63,371.36 inches = 1 mile
Now, we have 1,225 miles, this is equal to 1,125 times 63,371.36 inches
Then 1,225 miles writen in inches is:
1,125*(63,371.36 inches) = 71,292,780 inches.
Now, to write this in scientific notation, we need to count the number of decimals between the first one at the left, and the decimal point.
In this case we have 7 decimals.
Now, let's take the first 4 decimals, (7129) and write a decimal point after the first one:
(7.129)
Now let's multiply this by then to the power of 7 (where 7 is the number of decimals we found above).
Then the scientific notation of 71,292,780 inches. is:
(7.129)*10^(7) inches.

A They are parallel because they have the same slope of −2.
B They are parallel because they have the same slope of one half.
C They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
D They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answers
Answer:
C. They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.Step-by-step explanation:
Given lines
6x + 3y = 12 ⇒ 2x + y = 4 ⇒ y = -2x + 44x + 2y = 8 ⇒ 2x + y = 4 ⇒ y = -2x + 4The lines are same as both have same slope and y-intercept.
Correct statement is following:

Dana said that speed, s, could be either an independent or dependent variable. Write a situation where speed, s, is an independent variable. Then write a situation where speed, s, is a dependent variable.
Answers
Answer:
As dependent variable;
speed = distance/time
As independent variable
distance = speed * time
Step-by-step explanation:
When we say dependent variable, we mean that the value of the speed depends on some values.
When we say independent, we mean the value of some quantities is dependent on the speed.
As dependent variable;
speed = distance/time
As independent variable
distance = speed * time
Answer:
Part 1: C. Speed, s, could be an independent variable affecting the time it takes to walk a certain distance.
Part 2: A. Speed, s, could be a dependent variable based on how fast your legs move.

Graph the line with slope 2 and y-intercept - 7.
Answers
Answer:
you start on the y axis at -7 and you go up 2 and to the right 1
To graph the line with a slope of 2 and a y-intercept of -7, we can follow these steps .
The steps to be followed.1. Plot the y-intercept - Start by marking the point (0, -7) on the coordinate plane. This represents the y-intercept, which is the point where the line intersects the y-axis.
2. Use the slope to find additional points - Since the slope is 2, it means that for every 1 unit increase in the x-coordinate, the y-coordinate increases by 2 units.
This gives us a rise of 2 and a run of 1. Starting from the y-intercept, move up 2 units and right 1 unit to find the next point. Repeat this process to find more points.
3. Connect the points - Once you have a few points, draw a straight line through them. Since the slope is positive (2), the line will slant upward from left to right.
The resulting line should be a straight line that goes through the point (0, -7) and has a positive slope of 2. See the attacghed.

Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, which costs her a total of $23.75. If p represents the number of popcorn buckets and d represents the number of drinks, then the system of equations
Answers
Answer: the systems of equations to solve the unit price of popcorn and rinks are
1 p + 3 d= 12.50---- equation 1
3 p + 4 d= 23.75 ---- equation 2
The price of A popcorn bucket = $4.25 and price of 1 fountain drink = $2.75
Step-by-step explanation:
Step 1
If p represents the number of popcorn buckets
and d represents the number of drinks,
The expression that Brett buys 1 popcorn bucket and 3 fountain drinks for his family, which costs him a total of $12.50 becomes
1 p + 3 d= $12.50
and The expression that Sarah buys 3 popcorn buckets and 4 fountain drinks for her family, which costs her a total of $23.75 becomes
3 p + 4 d= $23.75
such that the systems of equations to solve the unit prices of popcorn and drinks are
1 p + 3 d= $12.50---- eqn 1
3 p + 4 d= $23.75 ---- eqn 2
Step 2
1 p + 3 d= $12.50---- eqn 1
3 p + 4 d= $23.75 ---- eqn 2
Multiplying equation 1 by( 3 )
1 p + 3 d= $12.50---- eqn 1 x 3
3p+ 9d= 37.5----- equation 3
and subtracting equation 2 from equation 3 becomes
3p+ 9d= 37.5----- equation 3
- 3 p + 4 d= $23.75
5d= 13.75
d= 13.75/5
d= 2.75
to find p, sinceaa d = 2.75,
1 p + 3 d= 12.50
1 p + 3 x 2.75= 12.50
p= 12.50-8.25
p=4.25
THerefore the price of popcorn = $4.25 and price of drinks = $2.75

brainliest and thanks <3
help asap
Answers
Answer:
length = 8
Step-by-step explanation:
l x w = 48
let l = 6w - 48
x(6w - 28) = 48
6w² - 28w - 48 = 0
(6w + 8) (w - 6) = 0
w = 6
l = 6(6) - 28 = 36 - 28 = 8
