Answer:
C, In many, many boxes of cereal of this type, we can expect about 75% of the boxes to contain a prize.
Step-by-step explanation:
All of them say "Expect", or "Exactly" other than this answer, but probability isn't Exact or Expected, so it is C.
Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
Step-by-step explanation:
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:
Solving the given equation, the value of v that makes the statement true is:
A. v = 8.
<h3>What is the given equation?</h3>
The equation is:
Hence:
Applying cross multiplication:
v - 8 = 0
v = 8.
Hence option A is correct.
