PLEASE HELP ME WITH MATH 1) If a child is 120 cm tall, but they grow 4 percent bigger in a year, how tall will they be?

2) A company uses 6,000 gallons of water each month. If they reduce their monthly water use by 12% how much water will be saved each month?

3) A new and improved snack has 22% fewer calories than it did before. If the old version had 200 calories, how many calories, how many calories does the new snack have?

4) Your friend wants to buy a pair of jeans that are on sale for 30% off. If the jeans original price is $40, how much will the sale price be?

5) Tom was able to save 35% more this year than he did last year. If he saved $140 last year, how much did he save this year?

down below

Step-by-step explanation:

1) 4% of 120 = 4.8, so 120+4.8 = 124.8 cm tall

2) 12% of 6000 = 720 .  6000-720 = 5280 gallons

3) 22% of 200 = 44 . 200-44 = 156

4) 30% of 40 - 12 .   40 - 12 = $28

5) 35% of 140 = $49 .  140 + 49 = $189

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
