Answer:

12%

Step-by-step explanation:

First, find how much salt is in each solution by multiplying the total amount by the percent of salt:

10(0.15)

= 1.5

15(0.1)

= 1.5

Added together, there are 3 pints of salt. There is a total of 25 pints, since 10 pints and 15 pints were mixed.

Find the concentration of salt by dividing 3 by 25

3/25

= 0.12

So, the concentration of salt in the solution is 12%

Esther drove to work in the morning at an average speed of 45 miles per hour. She returned home in the evening along the same ro
nydimaria [60]
The key is Esther travelled the same distance - x - in both her morning and evening commute.

45(time she took in the morning, or p) = x
30(time she took in the evening, or q) = x

Therefore 45(p) = 30(q), or divide both sides by 5 and get 9(p) = 6(q). I know you can divide it further, but these numbers are small enough and it's not worth the time.

Since the whole trip took an hour, (p + q) = 60min, and so, p = 60-q.

Therefore 9(60-q) = 6q or 540-9q = 6q. So 540 = 15q, which makes q = 36. If q = 36, then by (p+q)=60, p (the time she took in the morning) must equal 24.

45 miles per hour, her speed in the morning, times (24/60) hours, her time, makes 18 miles travelled in the morning. If you check, 30 miles per hour times (36/60) hours also makes 18 miles in the evening.

<span>Hope that makes a little sense. And I also hope it's right</span>

Murrr4er [49]

Answer:

<em>72 campers participated this year</em>

Step-by-step explanation:

<u>Percentages</u>

To determine x% of y, we must calculate x*y/100.

The number of campers that participated in Big Lake Camp during its first year was 40. We now want to know the number of campers that participated this year, if the attendance was 180% of the first year's.

The new attendance is calculated as follows:

40 * 180 / 100 = 72

72 campers participated this year
