The relationship between the cost, y, in dollars, of x pounds of concrete can be modeled by a proportional equation.

Answers

Answer 1

Answer:

Part A: 1.20 is y=20 is x

Part B= 9$

Step-by-step explanation:

Part A: if we notice our chart we will see that 4.80=80 so what we could do is say 1.20$ equals 20 pounds of concrete (you can do this differently for example 0.60$=10 pounds of concrete, but I just chose 20.)

Part B: If we want to find how much 150 pounds of concrete is we will first add 20 pounds 3 times giving us 140 pounds and then we split 20 and get 10, which equals 150, then we have to do the same thing for the cost, so 4.80+3.60=8.40 and then we split 1.20 in half giving us 0.60 which we then add to get 9$.

What r the options so i can get an idea

why are 3 non examples of perimeter

Answers

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape. ( I hope this is right)

peremeter is adding up all the sides

Answers

Answer:

She can buy 4 sets of earrings.

Step-by-step explanation:

Hi again,

We know that she wants to spend less than $25 and she already spent $9.50 on a necklace, we also know that each pair of earrings costs $3.50 so we can write an inequality...

9.5 + 3.5x < 25

( 9.5 is how much she already spent, 3.5 is the cost for every earring set, and we put a < because she wants to spend LESS than 25 not 25 or greater)

Now, solve...

9.5 + 3.5x < 25

Subtract 9.5 on both sides...

3.5x < 15.5

Divide by 3.5 on both sides...

x < 4. 43

You can't buy 4.43 sets of earrings, so the answer is simply 4. She can buy 4 sets of earrings.

Hope this helps and let me know if you need anything.

a cylinder has a height of 19 feet. the volume is 3,818.24 cubic feet. what is the radius?

Answers

Answer:

The radius is 32 cubic feet

Step-by-step explanation:

The formula to find the volume of a cylinder is V=Bh or V=πr2h. So you would need to work backwards because you already have the volume and height.

3,818.24= 3.14r2*19

3,818.24= 3.14r*38

Because of the associative property, you can multiply 3.14 by 38

which is 119.32

So the next expression would be

3,818.24= 119.32r

How do you reverse multiplication? You need to divide both sides. In this case, you need to divide 3,818.24 by 119.32.

To get 32=r

the answer is 32 cubic feet
