How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?
1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.
2. All 4 answers add up to 105ml.
3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution
4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution
50 + 52 + 54 = 156
The smallest one is 50 .
Answer:
75(1/3)^(n-1).
Step-by-step explanation:
This is a Geometric sequence whose common ratio is 15/75 3/15 = 1/3.
so the nth term an = a1 r^(n-1)
= 75(1/3)^(n-1).
