It is a 50 percent chance because she has ten jelly beans and there are 2o can all together so 10 out of 20 is 50%
Answer:
x=440 gaL 90 % Antifreeze II
Step-by-step explanation:
In the problem, there are two types of antifreeze
antifreeeze I and
antifreeze II
antifreeze I 25 ----80 gal
Antifreeze II 90 ----- x gal
Total 80 ---------------- (80 + x ) gal
(25*80)+(90*x)=80(80+x)
2000+90x=6400+80x
90x-80x=6400-2000
10x=4400
divide both sides by 10 we have
x= 440
x=440 gaL 90 % Antifreeze II
So the ceiling takes 5/6 gallon to paint. We know that you already have 1/30 gallon and another gallon in addition to that. We must convert the 5/6 into ?/30 so we can see how much we need to use. So if we convert 5/6 to out of 30, we get 25/30. So the first can has 1/30 gallon so we subtract that amount from the total paint needed. So now we only need 24/30 gallon to paint the ceiling. If we subtract that amount needed from the full (30/30) can we have left, that will give us the remaining amount of paint we have left. 30/30-24/30= 6/30. This reduces to 1/5. So there is 1/5 gallon of paint left over after painting the ceiling.
