Answer:
0.35 Gallons.
Step-by-step explanation:
Since there is already 9/10 in it, you can only pour 1/10 in now. 1/10th of 3.5 is 0.35.
Answer:
1/2
Step-by-step explanation:
Since this die has 6 sides, for each roll it has 6 outcomes.
Hence the probability of it landing on any specific number is 1/6.
Since there are only 3 outcomes wanted (roll less than 4 so it can be 1, 2, or 3) then we have to add the probability of each number being rolled so that is:
1/6 chance of rolling1
1/6 chance of rolling2
1/6 chance of rolling3
1/6 + 1/6 + 1/6
=3/6
=1/2
Let wind speed = x mph
when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.
when riding with the wind we have
20 + x = 3 / t--------(2) adding equations (1) and (2):-
40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr
x = 20 - 2 / 1/8 = 20 - 16 = 4
Wind speed was 4 mph Answer
