Answer:
<h2>C. None of the above</h2>
Step-by-step explanation:
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
Answer:
120 is the answer to the question
Answer:
$89.64
Step-by-step explanation:
First, you want to find your unit rate.
To do that, simply just divide what you know (cost/amount):
29.88/12
= 2.49
This means that one role of tape costs $2.49.
Now that we know that, you can simply just solve for value "c":
c = 2.49(36)
c = 89.64
Answer:
92
Step-by-step explanation:
Multiplying two negatives together results in a positive.
-23 * -4 = 23 * 4 = 92
