50 quarts of 5% butterfat and 1% butterfat milk are to be mixed.
<u>SOLUTION:
</u>
First, I will set up my table. I will fill in the unknowns with variables x and y.
The table is attached below
From the table attached below, we can easily set up the two equations.
<em>Sum of values of two milks = Value of mixture </em>
0.05x + 0.01y = 3
For convenience, we'll multiply the entire equation by 100,
5 x + y = 300 ------> (1)
Now, Sum of amounts of each acid = Amount of mixture
x + y = 100 ---------> (2)
Subtracting equation (2) from (1),
( + ) 5 x + y = 300
( − ) x - y = 100
− − − − − − − −
( = ) 4x + 0y = 200
Thus, 4x = 200
x = 50
Substituting x = 50 in (2),
( 50 ) + y = 100
y = 100 – 50 = 50
hence, 50 quarts of 5% butterfat and 1% butterfat milk are to be mixed.
Answer:
5.641 = x
Step-by-step explanation:
Work on the right triangle
pythag theorem
9^2 + L^2 = 10^2
L = sqrt 19
then x = 10 - sqrt 19 =5.641
Answer:
11/45
Step-by-step explanation:
Total number of customers:
21+34+83+54+33=225
Number of customers that go 1 or 2 days:
21+34=55
55/225 simplifies to
11/45
when divided by 5
