Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.

Answers

Answer:

25/20 =1.25 -1 =.25 x 100 =25% more time spent on his HW.

Step-by-step explanation:

Answer:

Evan spent 25 percent more time. Not 125 percent.

I used a proportion to answer this questions.

20=25

100 ?

You cross multiply: 25 times 100 is 2,500. 2,500 divided by 20 is 125.

So Evan is incorrect

A recipe for sparkling grape juice calls for
1/2
quarts of sparkling water and 3/4
quarts of grape juice

a. How much sparkling water would you need to mix with 9 quarts of grape juice?

b. How much grape juice would you need to mix with 15/4
quarts of sparkling water?

c. How much sparkling water would you need to make 100 quarts of punch?

d. How much grape juice would you need to make 100 quarts of punch?

Answers

A) 3/4 is equal to 0.75. 1/2 is equal to 0.5. You need to find out how many parts of the grape juice you have. So you take your 9 quarts and divide it by 0.75. That equals 12. So for the 9 quarts you need, you will add 12 parts of the 3/4. Now you need to add 12 1/2s as well. So 1/2 (or 0.5) multiplied by 12 is 6. So your answer would be 6 quarts

Answer:. A.) 6 quarts

B.) 45/8 quarts

C. 40 quarts sparkling water and 60 quarts of grape juice.

Once you get the basic ratio which is the amount of sparkling water is 2/3 the amount of grape juice, you can use that to set up as n equation for the next two questions.

Step-by-step explanation:

15/4 = 2x/3

Multiply both sides by the reciprocal:

3/2(15/4 = 3/2(2x/3)

45/8 = x

That is 5 5/8 quarts when simplified.

15/4 is 3 3/4 quarts

2 parts sparkling water to 3 parts grape juice is another useful ratio. Using that, 2x + 3x= 100 we can calculate

5x = 100

x 20. 2(20)=40 and 3(20)= 60

Diego has $11 and begins saving $5 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $60 and begins spending $2 per week on supplies for her art class.

1. After how many weeks will they have the same amount of money?

after ____ weeks.

2. How much do they have at that time?

$ ____.

Answers

Answer:

1. It should be 7

2. They have $46

Step-by-step explanation:

1. You make a system of linear equations from this. So it would be y= 5x+11 where x is the number of weeks and y is the money. And the second linear equation is y=-2x+60. Then you substitute it. You make it 5x+11=-2x+60. Then you solve it normally and you got your answer but remember in this case they are asking for the x. So make sure to submit the x and not the y.

2. For this it is the same thing except they are asking for the y not the x.

7 weeks they will have the same amount which is $46

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.
