12.Hi there, I've been struggling with the problem for quite a while and i have not been able to find
...
formula online to help.. It should be a simple straightforward problem but i just can not for the life of me figure it out. are you able to provide me with a formula or point me in the right direction?
The problem is:
Solution A has a 50% concentration
Solution B has a 100% concentration
Solution C has a 5% concentration
you have 5L of each solution to utilize as well as unlimited quantities of water to dilute solution concentrations if needed.
Part A
Make a final solution of 100ml with solution concentrations of Solution A 15%, solution C 5% and solution C 80%. how much of each solution will you need to make your final 100ml solution?
Part B
using the above solutions how many 100ml final solutions can you produce with the 5L volumes?
No matter how I work it i can't make the solution to the correct concentrations.
Thank you for your help.

25.Hi, I have one question on my math homework that I can't seem to figure out. Please help me! Here
...
is Imagine that in the voting for a certain award, 7 points are awarded for first place, 4 points for second, 3 points for third, 2 points for fourth, and 1 point for fifth. Suppose there were five candidates (A, B, C, D, and E) and 47 voters. When the points were tallied, A had 155 points, B had 173 points, C had 170 points, and D had 154 points. Find how many points E had and give the ranking of the candidates. (Hint: Each of the 47 ballots hands out a fixed number of points. Figure out how many, and take it from there.)
