There are 1000ml in 1L. There for there are 4x250ml in 1L. Multiply 5x4 gives you 20. Therefore he needs to fill 20 water bottles to fill the jug
12. The penny can land two ways (heads or tails) and the cube can land six ways (1, 2, 3, 4, 5, or 6). Therefore, there are twelve possible results.
Answer:
N = 5/6
Step-by-step explanation:
4/5 N= 2/3. Find N (solve for N).
Isolate N. To do this, multiply both sides of the equation by (5/4):
(5/4)(4/5)N= (5/4)(2/3)
becomes N = 10/12, or N = 5/6.
Answer:
Lisa would travel 417 miles a day.
Step-by-step explanation:
subtract 3,014 - 95 = 2, 919
Then divide 2, 919 / 7 = 417

Answer:
5 miles
Step-by-step explanation:
It may get a bit messy, but we can solve for the desired value directly. Let d = the distance walked (in miles). Then 20-d is the distance traveled in the car. The relevant relation is ...
time = distance / speed
The total travel time is 9:00 -6:50 = 2:10 = 2 1/6 hours = 13/6 hours. Here is the equation for total travel time.
total time = time spent walking + time spent riding
13/6 = (d/3) + (20-d)/30
Multiplying by 30 gives ...
65 = 10d + 20 -d
45 = 9d . . . . . . . . . . subtract 20
5 = d . . . . . . . . . . . . divide by 9
The girl walked 5 miles.
_____
<em>Check</em>
Her walking time was (5 mi)/(3 mph) = 5/3 h = 1:40.
Her riding time was (15 mi)/(30 mph) = 1/2 h = 0:30.
Her total travel time was 1:40 +0:30 = 1:70 = 2:10, as required.
