Answer:
9.) $90
10.) 12 schools
11.) 3:16
12.) 8
13.) 946 yards
14.) 20 miles
15.) 36.26 square meters
16.) $9.25 per hour
Explanation:
9.)
35 hours = $315
1 hour = 315/35
1 hour = $9
10 hours = 9*10
10 hours = $90
10.)
36 schools = 60 days
x schools = 20 days
since 20 is 1/3 of 60...
1/3 * 36 = 12
11.)
ratio: 15:(50+30)
simplify:
15:80
3:16
12.)
8 (I don't really know how to explain this one, sorry)
13.)
1 carry = 4.3 yards
220 carries = x
x = 4.3*220
x = 946 yards
14.)
Johnny = 60 miles
Shawn = 1/3 as much as Johnny
Shawn = 1/3 of 60 miles
1/3 * 60
20 miles
15.)
Area = length * width (or base * height in this case)
width = 7.4 meters
length = 4.9 meters
7.4*4.9 = 36.26 square meters
16.)
32 hours = $296.00
1 hour = 296/32
296/32 = $9.25
