Is "The weight of a stack of standard 8.5x11 copier paper vs. number of sheets of paper." a proportional relationship?
Answer:Yes it is proportional because w=kp k=paper weight which is constant. The relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional.
Step-by-step explanation:
Answer: Yes it is a direct proportional relationship
================================================
Explanation:
The equation is in the form y = kx, where
x = number of sheets of paper
k = weight of 1 sheet of paper
y = weight of all the x sheets of paper
x is some nonnegative whole number. The values of y and k are some nonnegative real numbers (aka any decimal values).
Note how if we had x = 0 pieces of paper, then y = 0 is the weight. So no paper leads to no weight. This visually is shown by the line y = kx going through the origin. All direct proportion equations go through the origin.
Each time we add a sheet of paper, we add on k ounces or k grams, or whatever units you're working with. The amount is constant assuming you are dealing with the same type of paper. Comparing y = kx with y = mx+b, we see that k plays the role of the slope or rate of change.

 Please create a graph to reflect the following situation:
Max is going to school. For the first 20 minutes he walks at a constant speed of 10 miles per hour. Then he gets to the bus stop and waits for the bus for another 5 minutes. Then he rides the bus for 10 minutes. The speed of the bus is 40 miles per hour.
Show graphically the distance Max has traveled to school over time since he has left his house.
Make sure you include the name of the graph, the labels and the scale on x- and y-axes; Please use graphing paper, pencil and a ruler. Please help me it’s due today I would love the help.
You show the time on the x-axes (from 0 to 35) and the distance on the y-axes (from 0 to 10).
You start at origin of coordinates. Then the graph rises linear until it reaches the point (20|3.3333...), then it is parallel to the x-axes (as he does not move) until it reaches (25|3.3333...). Then it increases again until it reaches (35|10).
Basically, it's linear all the time, while the slope of the graph varies in three different intervals. (Actually it wouldn't be linear as he doesn't move with the same speed all the time but we can't go more into detail based on the information we have, so we use average values.)
You can use the rule of three to find out how far he moves.

TRANSPORTATION The cost of riding in a cab is $3.00 plus $0.75 per mile. The equation that represents this relation is y=0.75x+3, where x is the number of miles traveled and y is the cost of the trip. Find and interpret f(17).
Answer:
f(17) = $15.75
The amount it takes for a trip of 17 miles is $15.75
Step-by-step explanation:
Here, we want to calculate f(17)
The equation is given as;
y = 0.75x + 3
For f(17), substitute x for 17
y = 0.75(17) + 3
y = 12.75 + 3
y = $15.75
What f(17) means is that the ride was for 17 miles
$15.75 is for a trip of 17 miles

I cant get an accurate answer for this problem Help!
Answer:
No solutions
Step-by-step explanation:
3(2y + 4) = 7y + 4 - y
~Simplify both sides
6y + 12 = 6y + 4
~Subtract 12 to both sides
6y = 6y - 8
~Subtract 6y to both sides
0 = 8
Best of Luck!

would a triangle with the sides of 16 m, 30 m, and 34 m make a right triangle?
Answer:
Yes, it would make a right triangle.
Step-by-step explanation:
A right triangle must follow the equation: a^2 + b^2 = c^2
16^2 + 30^2 = 34^2
256 + 900 = 1156
1156 = 1156
One degree of longitude at the equator is approximately 111 km. As we move north or south the size of a degree changes. How many kilometers would 1° of longitude measure in kilometers at 45° latitude north? A. 55.5 kilometers B.222 kilometers C. 444 kilometers D. 0 kilometers
Answer:
B.
Step-by-step explanation:
55.5 kilometers would be 1° of the longitude measure in kilometers at 45° latitude north.
What are longitude and latitude?Latitudes are horizontal lines that indicate how far away from the equator a location is. Longitudes are vertical lines that represent the east and west directions relative to Greenwich, England's meridian. Cartographers, geographers, and others can pinpoint points or locations on the globe by combining latitude and longitude.
Given, At the equator, one degree of longitude is around 111 kilometers. The size of a degree fluctuates as we go north or south. since the equator is perpendicular to the pole. which is 90 degrees hence it's asking distance of 45 therefore from the proportionality concept in a right angle triangle. the distance at 1 is at 45 latitudes is 111/2 or 55.5.
Therefore, At 45° latitude north, 55.5 kilometers would represent 1° of the longitude measurement in kilometers.
