Answer:
<h2>210 gaL 60 % Antifreeze II</h2>
Step-by-step explanation:
In the problem, there are two types of antifreeze
antifreeze I and
antifreeze II
antifreeeze I 20 ----70 gal
Antifreeze II 60 ----- x gal
Total 50 ---------------- (70 + x ) gal
20*70+60*x=50(70+x)
1400+60x=3500+50x
60x-50x=3500-1400
10x=2100
x= 210
x=210 gaL 60 % Antifreeze II
Answer:
25/56
Step-by-step explanation:
Prob of white = 3/8
Probability of not white = 1 - 3/8
= 5/8
Second pick without replacement
Probability of white = 2/7
Probability of not white = 1 - 2/7
= 5/7
Total probability = 5/8 x 5/7
= 25/56
X= # of miles
.55x+1.75 is greater than or equal to 10
So if she has to go more than 2 miles we will put 2 in for X
.55(2)+1.75 is greater than or equal to 10
.55×2= 1.10+1.75= 2.85
2.85 is greater than 10 is false so now we know she has to go more than 2 miles.
Let's guess and check. Now let's say 15 miles
.55×15= 8.25+1.75= 10
10=10 So she needs to drive at least 15 miles
x is greater than or equal to 15
Please don't solely rely on my answer I don't know if it's correct
