Answer:
Time left for each question is less than 5.5 minutes
Step-by-step explanation:
Given that:
Raphael is trying to solve 5 math questions in less than 20 minutes.
3 questions have been completed which have taken 3 minutes each.
To find:
How much time is left with Raphael for each question so as to reach his goal.
Solution:
First of all, let us find the time that has been already consumed by Raphael in solving the 3 questions.
3
3 = 9 minutes
Time left = Total Time - Time already consumed
Time left = 20 - 9 = 11 minutes
Number of questions to be solved = Total questions - Questions solved
Number of questions to be solved = 5 - 3 = 2
Average time left for each question = Time left divided by Number of questions to be solved
Average time left for each question = 11
2 = 5.5 minutes
Therefore, time left for each question is less than 5.5 minutes.
Answer:
True
Step-by-step explanation:
When multiplying two positives together the product is also positive
C.
In a proportion your numbers increase by the product of the proportion. So if at one point in your graph you had (2,20), the proportion is 10 (2*10=20). Therefore your next points should be 3,30 ;4,40 ; 5,50. Etc.
