Answer:
21
Step-by-step explanation:
18 feet = 18/3 yard = 6 yard
6 inches = 1/2 feet = 1/6 yard
Volumen = (6yar)(6yard)(1/6yard) = 6 cubic yard
Cost = 6 cubic yard * $42.00 / cubic yard = $ 252.00
Answer: the first option, 252.00
1. 1/10 (3000) = 3000/10 = 300...so 1/10 of 3000 is 300
300/10 = 30...and 300 is 10 times as much as 30
2. 10 times as much as 8 = (10 x 8) = 80
1/10x = 80
x = 80 * 10 = 800
so 1/10 of 800 is 10 times as much as 8
3. 1/10(50,000) = 50,000/10 = 5000
5000/10 = 500
1/10 of 50,000 is 10 times as much as 500
4. 1/10(40,000) = 40,000/10 = 4,000
4000/10 = 400
1/10 of 40,000 is 10 times as much as 400
5. 1/10 (900) = 900/10 = 90
10x = 90
x = 90/10
x = 9
10 times as much as 9 is 1/10 of 900
6. 1/10 (60,000) = 60,000/10 = 6000
10x = 6000
x = 6000/10
x = 600
10 times as much as 600 is 1/10 of 60,000
7. 70 x 10 = 700
1/10x = 700
x = 700 * 10
x = 7000
10 times as much as 700 is 1/10 of 7000
8. 10 x 2000 = 20,000
1/10x = 20,000
x = 20,000 * 10
x = 200,000
10 times as much as 2000 is 1/10 of 200,000
9. 10 times as much as 2000.....2000 x 10 = 20,000
1/10 of what is 20,000.....1/10x = 20,000....multiply both sides by 10, this eliminates the 1/10 on the left side....resulting in 200,000.
so basically, 10 times as much as 2000 = 20,000 and 1/10 of 200,000 = 20,000
Answer:
12 Rulers and 17 Pencils
Step-by-step explanation:
15 x 8 = cents spend
15 x 8 = 120
$5-120cents ($1.2) = $3.8 (380 cents)
380/30= 12 rulers with 20 cent remaining
20/8= 2 pencils with 4 cent remaining
now add!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
12 ruler +2 pencils +15 pencils=
12 Rulers and 17 Pencils
