Answer:
100
Step-by-step explanation:
Let x be the amount to be added of the second solution. For every 100ml of it 8 units of minoxidil are added. The total amount of solution will be (100 + x), so the final concentration is given by:
[Multiplying by (100 + x)]
[Transposing terms]
[
operating]
[Dividing by 0.02]

1 1/3 hours. 3/4 plus 7/12 equals 1 1/3. Hope this helps
Answer:
25π - 24 cm²
Step-by-step explanation:
area of circle:
A = πr²
A = π(5²)
A = 25π
Area of triangle:
base = 6
height = 5 - 1 = 4
(1/2)(6 * 4) = 12
there are 2 triangles so unshaded area is 24 cm²
Area of shaded region = 25π - 24 cm²
Total units= 1+3+6
=10
10 units= $40
1unit= $40/10
= $4
Person 1= $4 x 1
= $4
Person 2= $4 x 3
= $12
Person 3=$4 x 6
=$24
