Answer:

21 shelves

Step-by-step explanation:

I'm going to guess that you want to know if Kevin is correct in his estimate.

How many books are there is total?

12 boxes * 31 books/box = 372 books in total

Each shelf will hold 18 books so

372 books * [1 shelf /18 books] = 20.6666 shelves.

To be safe unless he wants to stake some of the left over books, he will need 21 shelves. You have to round up for the left over books. 20 shelves is a good estimate, but you will need just one more that has 1/3 of a shelf left over. He can put a picture of his family there.

DiKsa [7]
To answer this question you need to first set up the small, medium, large number of cakes as a ratio with a total. From here you will create a new ratio of the correct number of small medium and large Cakes sold using the total 216. The factor would be to multiply by nine. -Step 1 in picture. After this you would read what the relationship is between a medium and a small and the large and the small profits are - Step 2 in picture. After this you would represents the total profit based on the number of small medium and large cakes that were sold. Making this equal to L648.45. To find the profit for one small, you would then divide 648.45 by the 495 you got when you simplify the expression. The answer is L1.31.

miss Akunina [59]
The probability would be 1 out of 840.

This is a permutation problem. You have to determine the number of ways for each choice and multiply them together.

For the first choice, there are 7 states, then 6, then 5, and finally 4 choice for 4th spot.

7 x 6 x 5 x 4 = 840
