The ratio of green tiles to purple tiles in the art class mosaic is 5 to 8. There are 45 green tiles in the mosaic. Which shows a way to find the number of purple tiles in the mosaic?

Answers

Answer: you can use show the multiples of 5 and 8

Step-by-step explanation:for example show the multiples of 5 until you get to 45. Once you get there circle it. Then find the multiples of 8 and line it up until it lines up with the number 45. That’s how you do it hope this helps

Answer:
72 purple tiles
Explanation:
If the green tiles which is 5 for every 8 tiles and we know there are 45 green tiles, we can find the answer by dividing. 45/9=5, since we know we multiplied 9 to gain 45 we can multiply the same number to 8 to find the amount of purple tiles in the mosaic. (I hope this helps)

Solve the inequality.

3≤7+g

Answers

Answer:

g-4

Step-by-step explanation:

first subtract 7 from both sides

then you will get -4[tex]\leq[/tex]g

which is the same as g[tex]\geq[/tex]-4

you just have to switch them

The solution to the equation for inequality 3≤7+g is g ≥ -4. Equations and inequalities are both mathematical sentences that are formed by connecting two expressions.

How to solve the inequality ?

Equations and inequalities are both mathematical sentences that are formed by connecting two expressions. The symbol = indicates that the two expressions in an equation are deemed equal. In contrast, in an inequality, the two expressions are not always equal, as indicated by the symbols: >,, or.

You test the end point by plugging it into the related equation. The inequality is then tested to see if it is correct by substituting any other solution to see if it is one of the solutions.

Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :

                    3-(7+g)≤0

Pull out like factors :

  -4 - g  =   -1 • (g + 4)

Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     g+4  ≥ 0

Subtract  4  from both sides

           g ≥ -4

The solution to the equation for inequality is g ≥ -4.

Which statement best describes the relationship between the two cylinders shown below? (Use 3.14 for π.)



The volume of the cylinder on the left is greater.
The volume of the cylinder on the right is greater.
The volumes are equal.

Answers

answer:

the volumes of the cylindars are equal beacuse the right cylinder is simply squished down and made fat so the width and hight are flipped

hope this helped

-the chair with internet

The cylinder on the left, you can see that 4 ft is only halfway through the width, so :
4(2) * 7 *3.14 =
8*7 *3.14= 56
56*3.14 = 175.84
Answer for left cylinder: the volume of the left cylinder is 175.84.
Right cylinder:
7(2)*4*3.14=
14* 4 * 3.14 =
56 * 3.14 = 175.84
Answer for right cylinder: the volume of the right cylinder is 175.84, therefore, both of the cylinders volume is the same.

Solve number 32. . Show your work.

Answers

Answer:-4,0

Explanation:
If you are at a starting point of 1, 2 and you move in the left 5 in the X direction that would mean you are moving -5. So you would technically subtract 5 from 1 to get -4 (1-5=-4). For the second part you are moving down 2 in the Y direction. This would be the same thing. You are technically subtracting 2 from that Y number to get 0 (2-2=0) so your final coordinates would be (4-, 0)
(-2,0) , but if you move to point to the left 5 times and down 2 units it will be in the negatives and it will land on -2 and 0

An orchard has 28 apple trees and 12 pear trees. Select all the expressions that show the ratio of apple trees to pear trees.
A.7/3
B.3:7
C.28:12
D.7 to 3
E.12 to 28

Answers

It’s going to be B. Divide both of them by 4 to get them to smaller number to compare them

The quired ratio of apple trees to pear trees is  7/3. Option A is correct.

Given that,
An orchard has 28 apple trees and 12 pear trees.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of apple trees = 28
Number of pear trees = 12
Ratio of apple to pear = 28 / 12
                                     = 7 / 3

Thus, the quired ratio of apple trees to pear trees is  7/3. Option A is correct.
