Answer:
50 % alcohol solution = 10 millimetres
30 % alcohol solution = 90 millimetres
Step-by-step explanation:
two equations can be derived from this question
x + y = 100 equation 1
0.3x + 0.5y = 100 x 0.32 = 32
0.3x + 0.5y = 32 equation 2
where :
x = 30% alcohol solution
y = 50% alcohol solution
multiply equation 1 by 0.3
0.3x + 0.3y = 30 equation 3
subtract equation 3 from 2
0.2y = 2
y = 10
substitute for y in equation 1
x + 10 = 100
x = 100 - 10
x = 90

Answer:
D, 60 miles
Step-by-step explanation:
Distance is indicated by the vertical scale. The section that represents the most distance will be the section that has the greatest vertical difference between its start and end points. Section D starts at 60 and ends at 0 miles, so covers a distance of 60 miles. The greatest distance covered by any other section is 30 miles.
The person traveled the farthest during section D. They traveled 60 miles.
5 feet 5 inches is the same as 65 inches, so LAMAR is taller.
The axis of symmetry would be x=4.
Line A is the correct answer because the line crosses the 7 dish point at the one minute point
