Melanie is going to read a 219 page book. She reads at a rate of 20 pages per day. BAsed on this info which of the following statements is a reasonable conclusion
A.she will have read less than 1/2 of the book after 5 days
B.She will have read more than 13 of the book after 3 days
C.She will have read more than 138 pages after 4 days
D.She will have read fewer than 110 pages after 6 days
A
4.At the school pep rally 4 out of 7 students wore colors. Based on this info if 350 students attend the next pep rally how many of these students will wear school colors
A.150
B>50
C>200
D.not here
D
Both answers are right.
The answer to number 1 is: (A)
The answer to number 2 is: (D)
I'm sorry I made a typo. For number 4 it's actually 3 out of 7 not 4. But would it still be D?
No. 4 is not D.
To find the answer to the first question, we can calculate the number of pages Melanie will read after a specific number of days.
Given that she reads at a rate of 20 pages per day, we can calculate:
After 1 day: 20 pages
After 2 days: 20 + 20 = 40 pages
After 3 days: 40 + 20 = 60 pages
After 4 days: 60 + 20 = 80 pages
After 5 days: 80 + 20 = 100 pages
After 6 days: 100 + 20 = 120 pages
Now, let's review each statement to determine which one is a reasonable conclusion:
A. She will have read less than 1/2 of the book after 5 days
After 5 days, she will have read 100 pages. Since the book has 219 pages, 100 is less than half of the book, so this statement is true.
B. She will have read more than 13 of the book after 3 days
After 3 days, she will have read 60 pages. Since 60 is greater than 13, this statement is true.
C. She will have read more than 138 pages after 4 days
After 4 days, she will have read 80 pages. Since 80 is less than 138, this statement is false.
D. She will have read fewer than 110 pages after 6 days
After 6 days, she will have read 120 pages. Since 120 is greater than 110, this statement is false.
Based on the analysis, statement A is the reasonable conclusion.
For the second question, we are given that 4 out of 7 students wore school colors at a pep rally. We can calculate the proportion of students who wore school colors:
Proportion of students wearing school colors = (Number of students wearing school colors) / (Total number of students)
Proportion of students wearing school colors = 4 / 7
To find out how many students would wear school colors out of 350 students, we can multiply the proportion by 350:
Number of students wearing school colors = (4/7) * 350
Number of students wearing school colors ≈ 200
Therefore, the answer is C. Around 200 students will wear school colors out of 350 students.
