Answer:
3 people
Step-by-step explanation:
If there are 16 people in the first lecture and 6 people have brown eyes, the ratio is 6:16. If in the next lecture there is 8 people, all that needs to be done is halving the numbers in the original ratio (to get 16 to 8). Therefore, the ratio is 3:8, meaning 3 people out of 8 would have brown eyes.
Answer:
Step-by-step explanation:
This can be set up like an inequality. Chances are just as likely that you are in ratios and proportions, but since I'm not sure, I'm going with the easier way for this particular situation. The inequality, before reducing, is:
20 < 4x < 40,
which states that a 4 minute shower uses less than 40 gallons but greater than 20 gallons, where x is the number of gallons of water. Therefore,
5 < x < 10 results when you simplify. This puts things in terms of 1 minute now. This states that a 1 minute shower uses less than 10 gallons of water but more than 5 gallons. We got this by dividing everything by 4.
Now that things are in terms of a single minute, all you have to do is multiply the greatest number of gallons by 18 and the least number of gallons by 18 (and the x as well) to get the number of gallons used in an 18 minute shower as a range:
90 < 18x < 180
The correct answer is c . E
C. 1/5. Because there is only one answer that is the right answer to each multiple choice. Also, there are 5 choices for us to choose.
