Answer:

60 pounds of skimmed milk to be removed

Step-by-step explanation:

Given that 300 pounds of milk is testing 3 % of milk

It means;

3% of fats = 300 pounds of milk

or

1% of fats = 100 pounds of milk -------------(1)

Now let x% of fat be added to present value of fats so that it becomes 3.6% of fats

i-e

x+3=3.6

this gives  x=0.6% of fats needs to be increased

but from eq (1)    we know  

1% of fats =100 pounds of milk

so, 0.6% of fats = 0.6x100=60 pounds of skimmed milk is to be removed .

Calculate the length of CD give your answer to 3 significant figures.
Westkost [7]

12.7  
Using the Pythagorean theorem, you can easily calculate the length of BC.
So: 
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485  
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So: 
BC/sin(55) = CD/sin(90) 
BC/sin(55) = CD/sin(90) 
sin(90)BC/sin(55) = CD 
1*BC/sin(55) = CD 
BC/sin(55) = CD 
10.39230485/0.819152044 = CD 
12.68666167 = CD 
12.7 = CD
