Answer:
50 % alcohol solution = 10 millimetres
30 % alcohol solution = 90 millimetres
Step-by-step explanation:
two equations can be derived from this question
x + y = 100 equation 1
0.3x + 0.5y = 100 x 0.32 = 32
0.3x + 0.5y = 32 equation 2
where :
x = 30% alcohol solution
y = 50% alcohol solution
multiply equation 1 by 0.3
0.3x + 0.3y = 30 equation 3
subtract equation 3 from 2
0.2y = 2
y = 10
substitute for y in equation 1
x + 10 = 100
x = 100 - 10
x = 90
Honestly, I don't think there is a certain method or anything to find how much candy corn there is in that jar. Try counting and rounding or just take a solid guess ! You'll maybe be closer to the answer by taking a solid guess ! Good luck :)
Answer:
I would say 1 lbs of dog food is equivalent to 4 4/7 meals.
7/8 lbs : 4 meal = 1 lbs : x meals 1 lbs = 8/8 lbs perform cross 7/8 lbs (x) = 8/8 * 4 7x/8 = 8*4 / 8*1 7x/8 = 32/8 7x/8 = 4 8(7x/8) = 8*4 7x = 32 7x/7 = 32/7 x = 4 4/7 meals to 7/8 : 4 = 1 : 4 4/7 7/8 * 32/7 = 4 * 1 224/56 = 4 4 = 4
