PLZ I HAVE TO FINISH THIS TEST TODAYYY
Answers
Answer:
4 tickets for $1
Step-by-step explanation:
I just divided 8 with 2.00 and got 4.
The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
At a school carnival, tickets can be purchased to participate in different activities.
The data are shown in the picture.
From the data:
y ∝ x
Removing the proportional sign:
y = kx
Plug x = 8
y = 2
2 = 8k
k = 1/4
Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

Here is a balanced hanger diagram in which a circle has a mass of 3 grams and a square has a mass of 2 grams.
Which equations could represent the diagram, assuming t represents the triangles?
3c + 2s + 2t = 3c + 2s + 5t
2t + 21 = 5t + 12
3(3) + 6(2) + 2t = 2(3) + 3(2) + 5t
2t + 9 = 5t + 5

name 5 fractions whose values are between 1/2 and 7/8
Answers
Answer:
3/4, 4/6, 5/8, 2/3, 6/10
Step-by-step explanation:
The five fractions that provide a range of values between 1/2 and 7/8 are 5/8, 3/4, 11/16, 2/3, and 13/16.
Here are five fractions that lie between 1/2 and 7/8:
5/8: This fraction is greater than 1/2 but less than 7/8. It can be obtained by dividing 5 by 8.
3/4: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 3 by 4.
11/16: This fraction is closer to 1/2 and slightly less than 7/8. It can be obtained by dividing 11 by 16.
2/3: This fraction is greater than 1/2 and closer to 7/8. It is obtained by dividing 2 by 3.
13/16: This fraction is closer to 7/8 and greater than 1/2. It can be obtained by dividing 13 by 16.
These five fractions provide a range of values between 1/2 and 7/8. They demonstrate different proportions and can be used in various contexts where a fraction between 1/2 and 7/8 is required, such as measurement, comparison, or estimation.

Answer:
Radius is the distance from the center outwards
Diameter goes straight across the circle, through the center.
Step-by-step explanation:
Hope this Helps!!
let me know if it doesn't
Answer:
Step-by-step explanation:
Diameter is the longest line that you can draw in a circle passing through the centre of the circle.
Radius is the line joining the centre of the circle to any point on the circumference.
Explanation:
Diameter is the ratio of the circumference of the circle to the irrational constant 'pi' (3.1415...). Radius is the half of the diameter.
D=2x radius and radius =D/2
Actually pi is defined to be the ratio of the circumference of the circle to the diameter of the circle. Therefore, you can solve for the diameter from that equation.
π=C/D , D=C/π Or , C=π x D

The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are there?
Answers
This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x
We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8
If this helped, give me brainliest :)
Answer:
8 red marbles.
Step-by-step explanation:
The ratio is 3:2, blue to red. If there's 12 blue marbles and the first part of the ratio's 3, then:
12/3=4
Then you take the 4 and multiply it by 2, the second half of the ration to get 8.
And so, the answer's 8. If you divide 12:8 by 4 each you get your original ratio of 3:2, so that's your way to check.

Answers
A linear equation should have points that graph in a straight line.
Step-by-step explanation:
I hope it help !
A linear equation should have points that graph in a straight line.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
A linear function is a function in which the slope remains constant.
Since a straight line has a constant slope thus it will represent the straight line.
Hence "A linear equation should have points that graph in a straight line".
