The population was 5,000 five hours ago!!
Answer:
Step-by-step explanation:
The water has to be 100% - 60% = 40%
100% represents both water alcohol (I think that's what you meant).
40% of 250 = 40/100 * 250 = 10000/100 = 100 mL
So 100 mL = water
150 mL = alcohol.
The answer would be choice C.
Perpendicular lines cross each other and form a right angle as you can see marked in the third picture.
Something I noticed about angle 4, is that it shares a straight line with angle 3. (above it is a straight line)
A straight line equals 180 degrees.
So, angle 4 + angle 3= 180 degrees.
Angle 3 is congruent to angle 7.
180-132= Angle 7
180-132= 48
48 degrees is your answer.
I hope this helps!
