I have milk that contains 1 percent fat and milk that contains 4 percent fat. a customer wants a double latte made with 1/3 of a pint of 2 percent milk. how much of each type of milk should i use ?
Solution 1
The double lathe milk with 2 percent fat concentration, is made by
considering the concentration and amount of each constituent.
The amount of each type of milk to be used in the pint of double lathe
are;
-
pint of the 1 percent fat milk and
pint of the 4 percent fat milk.
Reasons:
Let x represent the amount of the milk that contains 1 percent fat in the
volume of the 2 percent fat milk.
Therefore, we have;
The amount of the 4 percent fat milk to be used =
Therefore;
4 - 9·x = 2
4 - 2 = 9·x
The amount of the 1 percent fat milk to be used for the double lathe, x =
of a pint.
The amount of the 4 percent fat milk to be used for the double lathe =
Therefore;
The mount of the 4 percent fat milk =
The amount of the 4 percent fat milk to be used for the double lathe =
pint.

Solution 2
Let x be the amount of 1% milk used. 1% = 1/100 = 0.01; this gives us 0.01x to represent this.
We know that we will use the 4% milk to make up the rest of the 1/3 pint; this gives us 0.04(1/3-x).
Together, they will make 1/3 pint of 2% milk, or 0.02(1/3)
This gives us the equation
0.01x+0.04(1/3-x) = 0.02(1/3)
Multiplying, we have
0.01x+0.04/3-0.04x = 0.02/3
We can multiply everything by 3 to eliminate the fractions:
0.01x*3 + 0.04 - 0.04x*3 = 0.02
0.03x + 0.04 - 0.12x = 0.02
Combining like terms, we have
-0.09x + 0.04 = 0.02
Subtract 0.04 from both sides:
-0.09x + 0.04 - 0.04 = 0.02 - 0.04
-0.09x = -0.02
Divide both sides by -0.09:
-0.09x/-0.09 = -0.02/-0.09
This gives us x = 2/9, so we will use 2/9 of a pint of the 1% milk.
1/3 - 2/9 = 3/9 - 2/9 = 1/9; we will use 1/9 of a pint of the 4% milk.

Answer:
An angle measures how how much you have to rotate one line called initial side so it lies on the top of other line called the terminal side. Angles whose vertex is located at the origin having the initial side on the positive x-axis is said to be in standard position. On the other hand, coterminal angles are angles in standard position having the same terminal side. In this way, for the angle:
