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
From left to right:
Negative, positive, none, nonlinear
1 is negative bc it has a negative slope
2 is positive because it has a positive slope
3 has no correlation because there is no pattern
4 is no linear because it’s not in a line, essentially. (This would be a parabola)

Answer:
200
Step-by-step explanation:
Surface are of cube = 6a^2
A -5/8
B -15/24
because -30/48 divided twice will equal -15/24 which explains the second answer and -15/24 divided by three will equal -5/8
