5 out of (3+5) are women 5/ 8 x 208 =......
If there are 5 boys in 12 person class then there are 12-5 = 7 girls
ratio of boys to girls would be 5:7
ratio of girls to all students would then be 7:12
6% * x = 1000
.06 * x = 1000
x = 1000/ (.06) =.........
Chance that is DOESN't snow 2/3 x 2/3 x 2/3 x 3/4 x 3/4 x 3/4 x 3/4 = 8/27 x 81/256 = 648/6912
1 - 648/6912 = 6264/6912 = 29/32 chance of snow (??)
Rate x time = distance
distance / rate = time
30 miles/ 30 m/hr = 1 hr
30 miles / 60 m/hr = 1/2 hr
(30 m + 30m) / (1 + 1/2 hr) = 60 m/1.5 hr = 40 m/hr average
9 pizzas x 8 slices/pizza = 72 slices
72 slices / 23 students = 3 slices/student ....each student can have approx 3 slices (rounded answer)
You have 2 rates and the time involved to complete 1 round trip
rate x time = distance
d/60 + d/30 = 1.25 ( 1.25 hour = 1 hour 15 min)
d/60 + 2d/60 = 1.25
3d/60 = 1.25
3d = 75
d = 25 miles
The question does not ask what percent increase is it from 40 to 90.....
it asks what percentage is 90 of 40.....
100% of 40 is 40
200% of 40 is 80
225% of 40 is 90
Each dumbell weighs 3 3/5 kg
3 3/5 kg/dumb x 3 dumb = 18/3 x 3 = 54/3 = 18 kg (the amount EACH BOX weighs)
2 boxes x 18 kg/box = 36 kg for 2 boxes
2 hr 40 min + 1 hr 25 min = 3 hr 65 min= 4 hr 5 min
8 hr 35 min - 4 hr 5 min = 4 hr 30 min 4:30 PM
