Q: Karen is planning writing assignments for her fifth grade class. She knows each short-answer question takes 3 minutes to answer, each paragraph takes 15 minutes to write, and each essay takes an hour to write. If Karen assigns 2 essays and 5 paragraphs, how many short-answer questions should she assign if she wants to assign 4 hours of homework total?
A: First figure out how many minutes 4 hours is: 4 hours * 60 minutes / hour = 240 minutes. Then figure out how long the two essays will take by multiplying the time per essay by the number of essays: 2 essays * 1 hour / essay * 60 minutes / hour = 120 minutes. Use the same method to find the total time spent writing paragraphs: 15 minutes / paragraph * 5 paragraphs = 75 minutes. Now subtract the time spent on essays and paragraphs from the total time to find the time spent on all the short answer questions: 240 minutes - 120 minutes - 75 minutes = 45 minutes. Finally, divide the total time spent on short - answer questions by the time per question to find the number of questions: 45 minutes / 3 minutes / question = 15 questions. The answer is 15.
Question: In the matrix, there are seven fewer noodles than pirates. If there are 45 pirates, how many noodles and pirates are there in total?
Answer: In the matrix, there are seven fewer noodles than pirates, meaning there are 45 - 7 = 38 noodles. The number of noodles and pirates in the matrix is 38 + 45 = 83. The answer is 83.

Q: Maria is baking cookies for Sally. Sally says that she wants 1/4 of her cookies to have nuts in them, 40% to have chocolate chips in them, and the remainder to have nuts and chocolate chips in them. When she adds nuts to the cookies, she uses 2 nuts per cookie. If she makes 60 cookies, how many nuts does she need?
A: 35% of the cookies have nuts and chocolate chips because 100 - 25 - 40 = 35. 60% of the cookies have nuts in them because 25 + 35 = 60. She makes 36 cookies with nuts in them because 60 x .6 = 36. She needs 72 nuts because 36 x 2 = 72. The answer is 72.
Question: When it rains, the three holes in the garage roof leak water at different rates. The largest hole leaks at a rate of 3 ounces of water per minute. The medium-sized hole leaks water at one-half the rate of the largest hole. And the smallest hole leaks water at a rate of one-third the rate of the medium-sized hole. When it rains, what is the combined amount of water, in ounces, that leak from all three holes over a 2-hour time period?
Answer:
The medium - sized hole leaks at a rate of one - half that of the largest hole, or 3 / 2 = 1.5 ounces per minute. The small - sized hole leaks at a rate of one - third that of the medium - sized hole, or 1.5 / 3 = 0.5 ounces per minute. Combined, the three holes leak at a rate of 3 + 1.5 + 0.5 = 5 ounces per minute. Since one hour is 60 minutes, two hours is 2 * 60 = 120 minutes. In total, over the two hours, the three holes will leak a combined 120 * 5 = 600 ounces of water. The answer is 600.
