the airplane new altitude is 17500
20000-2500=17500
Answer:
Part A
x = liters (the milk and water)
0.2 x + 1 = x
Part B
0.2 x + 1 = x
0.8 x = 1
x = 1 : 0.8 = 1.25 liters
Milk
1.25 x 0.2 = 0.25
Notice the picture below
see where that angle is?
check your Unit Circle for that value
also notice, that fractions of

are just like grabbing 180 degrees and splitting it, so one third of 180 or

is 180/3 or 60 degrees
