Apharmacist has a 10% alcohol solution and a 25% alcohol solution. how many milliliters of each solution will she need to mix together in order to have 200 ml of a 20% alcohol solution?

x = volume of 10% solution to use in the mixture

y = volume of 25% solution to use

She wants a 200 mL solution, so x + y = 200.

The first solution contributes 0.10x mL of alcohol, while the second contributes 0.25y mL. Together, they make a solution with 0.20(x + y) = 0.20(200) = 40 mL of alcohol.

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
