Answer 1

Answer:

1) c and d

2) 44

3) a and c

1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.

2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.

3:  the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.

Answer 2

Answer:

1. C and D.

2. 34

3. A and C

Step-by-step explanation:

1. All you have to do is solve each equation in order to see which ones are equal to the same answer

A. 32 * 96 = 3072

B. 3.2 * 96 = 307.2

C. 0.32 * 96 = 30.72

D. 32/100 * 96 = 30.72

Both C and D have the same answer.

2. Add up all the sides

9+6+5+4+3+3+2+2= 34

3. Look at each answer carefully.

A. There are 2 blue cubes for every 5 red cubes. True

B. When the game has 56 cubes in all, there are 40 red cubes. False

C. The ratio of red to blue cubes is 10:4. True

D. The ratio of all cubes to blue is 28:20. False

A cell phone battery with 22% charge takes 176 minutes to run out. How long will a fully charge battery last?

Answers

Answer:

800

Step-by-step explanation:

176 divided by 22=8

8x100= 800

It will take 13.33 hours to battery run out.

What is unit rate?

A unit rate means a rate for one of something.

Given that, A cell phone battery with 22% charge takes 176 minutes to run out.

In 22% → 176 minutes

In 1% → 176/22 = 8 minutes

In 100% → 8x100 = 800 minutes

800 minutes = 800/60 = 13.33 hours.

Hence, the battery will work for 13.33 hours when charged 100%

Answers

Answer:

Percentage Change | Increase and Decrease

hopefully this helped and you can find the percent change.

I think you would do
6,570 divided by 16,425
And that would get you
