Does the size of a circular object affect the relationship between its circumference and its diameter?
A. The size will affect the relationship between circumference and diameter because of circumference changes at a greater rate than the diameter.
B. The size has no effect on the relationship between circumference and diameter because the ratio is always equal to
C. The size has no effect on the relationship between circumference and diameter because the two values change independently.
D. The size will affect the relationship between circumference and diameter because of the value changes as the circumference changes.
Answer: A
Step-by-step explanation: It doesn't. The circumference of a circle is 2*pi*radius and the diameter is 2*radius, so the circumference divided by the diameter is pi, which is the ratio of circumference to diameter.

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.

Answer:
a) 4 quarts of sparkling water
b) 38.5 quarts of grape juice
c) 80 quarts of sparkling water and 20 quarts of grape juice
The answers for the letters in the chart are on the bottom for b and c.
Step-by-step explanation:
a) You would need 4 quarts of sparkling water for 1 quart of grape juice.
This proportion is to get the amount of grape juice you need you multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
So for a) I know that .25 of a quart of grape juice is equal to 1 quart of sparkling water. So to get the amount of sparkling water multiply the amount of grape juice you need by .25. And the number you multiplied .25 will be the amount of sparkling water you need. Example: 4 × .25 = 1 quart of grape juice.
4 is the amount of sparkling water you need.
b) For b you just need to multiply the amount of sparkling water by .25 to get the amount of grape juice you need.
154 × .25 = 38.5
You need 38.5 quarts of grape juice.
c) You would need 80 quarts of sparkling water and 20 quarts of grape juice.
80 × .25 = 20
b on the graph is 38.5 because 154 × .25 = 38.5
c on the graph is 400 because .25 × 400 = 100

Solve the equation.
2.5 = 0 - (-20)
0-17.5
0-22.5
O 22.5
0 17.5
Answer:
Step-by-step explanation:Simplifying
0 = 2.5y + -20
Reorder the terms:
0 = -20 + 2.5y
Solving
0 = -20 + 2.5y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2.5y' to each side of the equation.
0 + -2.5y = -20 + 2.5y + -2.5y
Remove the zero:
-2.5y = -20 + 2.5y + -2.5y
Combine like terms: 2.5y + -2.5y = 0.0
-2.5y = -20 + 0.0
-2.5y = -20
Divide each side by '-2.5'.
y = 8
Simplifying
y = 8
SO the answer is y=8 I think srry if i get it wrong

Please explain your answer.
Answer:
The Answer here is 11
Step-by-step explanation:
First, we divide inside the parentheses because we always do what is inside the parentheses first, and division comes before addition. So 12/4 is 3. Next we add 3 plus 1, which is 4. Then we multiply (Because multiplication comes before subtraction, and parentheses mean multiplication) 4 times 1 which is 4. Then we subtract 15-4 which comes out to 11.
Hence the answer here is 11.
