Sure! I'd be happy to help you solve these problems using the given table.

Q1: To find the number of shelves needed for 9 history books on each shelf, we divide the total number of history books by 9. So, 72 divided by 9 is equal to 8. Therefore, there will be 8 shelves in that bookcase.

Q2: Similarly, to find the number of cookbooks on each shelf, we divide the total number of cookbooks by the number of empty shelves. So, 36 divided by 9 is equal to 4. Therefore, there will be 4 cookbooks on each shelf.

Q3: To determine the number of types of books that will have an even number on each shelf, we need to analyze the given table. Unfortunately, the table you provided does not clearly indicate the number of books in each subject that can be evenly distributed among the shelves. Therefore, it is not possible to determine the answer to this question without additional information.

Q4: To identify the two subjects for which it would take 7 shelves with 9 books on each, we need to look for a subject that has a total count of 63 books (since 7 multiplied by 9 equals 63). Looking at the table, we find that the "Travel" subject has a count of 63 books. Therefore, one of the subjects is "Travel." To find the other subject, we look at the remaining counts and see that the only subject that can combine with "Travel" to get a total of 63 books is "Biography," which has a count of 45 books. So, the two subjects are "Travel" and "Biography."

Q5: For this question, we are asked to find the number of books on each shelf when shelves are filled with travels, history, and biography books. There are two possible approaches to solving this.

Approach 1:
We divide the total number of books (180) by the total number of shelves (9). So, 180 divided by 9 is equal to 20. Therefore, there will be 20 books on each shelf.

Approach 2:
We divide the total number of books for these three subjects (63 + 72 + 45 = 180) by the total number of shelves (9). So, 180 divided by 9 is equal to 20. Therefore, there will be 20 books on each shelf.

Both approaches yield the same result, so the answer is 20 books on each shelf.

Q6: To determine the number of books Raul would have to buy to have 10 books on each shelf, regardless of the subject, we need to find the total number of shelves. Unfortunately, we cannot determine the total number of shelves without knowing the number of books in each subject. As a result, it is not possible to answer this question with the given information.

I hope this helps! Let me know if you have any further questions.
