For each situation, explain whether you think the relationship is proportional or not. Explain your reasoning.
The weight of a stack of standard 8.5x11 copier paper vs. the number of sheets of paper.
The weight of a stack of different-sized books vs. the number of books in the stack.
Answer:
A. Yes
B. No
Step-by-step explanation:
We have that,
A. The dimensions of the each of the paper is 8.5 × 11.
Since, the papers have equal dimensions, the weight of every paper will be same and it will be easy to find the number of papers using direct proportion.
Thus, the weight of the paper and the number of papers is proportional.
B. It is given that the weight of each book is different.
Since, all the books have different weights, it is not easy to find the number of papers using direct proportion.
Hence, the weight of the books and the number of books is not proportional.

Answer:
Answer 19:- x = 5
Answer 20:- x = 11
Step-by-step explanation:
Answer 19:-
2x + 10 = 20
2x = 10
x = 5
Answer 20:-
80 + 20x = 300
20x = 220
x = 11
Answer:
19. x = 5
This is because Elise need $20, so we are going to figure out x
First, subtract 10 by both sides
2x = 10
Then, divide both sides by two to isolate the variable
x = 5
5 cars is the minimum
================================================================
20. He can stay for 11 nights.
First we subtract 80 by both sides
20x = 220
Then we isolate the variable by dividing both sides by 20
x = 11

Step-by-step explanation:
Mr. Santos treated his students to a movie for winning the state contest. This also required taking some of the students’ parents as chaperones. The movie theatre charges $4 for each student and $6 for each adult. If Mr. Santos spent $180 on movie tickets and took 40 people (including himself), how many students did he take to the movies.
write two equations to help find the answer
Answer: 41
Step-by-step explanation:
Using a system of equations, it is found that he took 30 students to the movies.
------------------------------
This question is solved using a system of equations, and I will say that:
x is the number of students taken.y is the number of adults taken.------------------------------
40 people were taken, and thus:
[tex]x + y = 40[/tex]
As we want the number of students x, we can represent y as function of x, thus:
[tex]y = 40 - x[/tex]
------------------------------
Each student costs $4.Each adult costs $6.The total amount spent was $180.Thus:
[tex]4x + 6y = 180[/tex]
Since [tex]y = 40 - x[/tex]
[tex]4x + 6(40 - x) = 180[/tex]
[tex]4x + 240 - 6x = 180[/tex]
[tex]-2x = -60[/tex]
[tex]2x = 60[/tex]
[tex]x = \frac{60}{2}[/tex]
[tex]x = 30[/tex]
He took 30 students to the movies.

Suppose that a scuba diver is currently 34 feet below sea level. If he descends at a rate of 2 feet per minute, in how many minutes will it take for the diver to reach 126 feet below sea level?
Answer:
46 minutes I think
Step-by-step explanation:
Your already 34 feet down so subtract 34 from 126 which is 92. Put the two aside for a second and divide 90 by 2 which is 45 and since it take 1 minute to get down 2 feet it will take 45 to get down 90. Back to the 2, you will add one more to 45 which is 46 because it will take one more minute to get down those other 2 feet.
