Answers

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

HOpe this helps ya!!

a is 4 quarts of sparkling water
b is 38.5 quarts of grape juice
c is 80 quarts of sparkling water and 20 quarts of grape juice

A computer that costs x dollars wholesale is marked up 20% at a store.
Which expression represents the final price of the computer?
A. x + 0.20
B. 1+0.20x
C. (1 + 0.20) x
D. (1 + x) 0.20

Answers

Answer: A

Step-by-step explanation:

1. 20 percent is equal to 20/100.

2. 20/100 equals 0.20.

3. x + 0.20 is the answer.

4. The answer is A.

The final price of the computer can be represented as (1+ 0.20)x.

Option (C) is correct.

What is percentage?

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

Initial price of the computer = x dollars,

The marked up price of the computer = 20%.

To find expression for final price of the computer,

Final price = initial price + marked up price

                  = x + x × (20/100)

                  = x + 0.20x

                  = (1+ 0.20)x

The final price of the computer will be (1+ 0.20)x.

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

The rate of change is referring to the slope, which can be calculated by rise/run.  There are two points we can use to find the slope: (0,3) an (4,6), but feel free to use any points on the graph that you want to.  Between those two points, the function's y value ("rise") increases by 3, while the function's x-value ("run") increases by 4.  Divide 3 (rise) by 4 (run) in order to calculate the rate of change.

Please explain your answer.

Answers

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.
