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

The answer is: 8 red marbles!

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.

A giant "Family Size" box contained 14.7 oz and cost $5.99. A small, individual size contained 1.5 oz and cost $1.89. He wanted to get the most "bang for his buck." Which choice is the better buy? In other words, which choice is cheaper per ounce? Which one should he buy and why?

Answer:

The answer is the family size

Step-by-step explanation:

A linear equation should have points that graph in a _____________ line.

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".

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

What is the constant of proportionality that relates y , the total cost in dollars, to x , the number of tickets purchased?




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.
