Question: One pair of pants requires 8.5 feet of fabric. Nguyen needs to make 7 pairs of pants for the wedding. He has 3.5 yards of fabric. How many feet of fabric does Nguyen still need for the pants?
Answer: Step-by-step reasoning process: Pants = 8.5 * 7 = 59.5 feet. 3.5 yards = 10.5 feet. 59.5 - 10.5 = 49. Nguyen still needs 49 feet of fabric.
So the answer is 49.

Question: The ratio of fuel used in gallons to the distance covered in miles by Haley's car is 4:7. If Haley's car used 44 gallons of gas, calculate the distance it covered in miles.
Answer: Step-by-step reasoning process: The total ratio representing fuel consumption and distance traveled is 4 + 7 = 11. If 4 / 11, which is the fraction representing fuel consumption, represents 22 gallons of gas, then 7 / 11 representing distance covered represents 7 / 11 * 44 * 11 / 4 = 77 miles.
So the answer is 77.

Question: While practising for his upcoming math exams, Hayes realised that the area of a circle he had just solved was equal to the perimeter of a square he had solved in the previous problem. If the area of the circle was 100, what's the length of one side of the square?
Answer: Step-by-step reasoning process: Let's say the side of a square is s.To get the perimeter of a square, you add all the sides, which is s + s + s + s = 100. Therefore, 4s = 100. Therefore one side of the square is s = 100 / 4 = 25.
So the answer is 25.

Question: Bert fills out the daily crossword puzzle in the newspaper every day. He uses up a pencil to fill out the puzzles every two weeks. On average, it takes him 1050 words to use up a pencil. How many words are in each crossword puzzle on average?

Step-by-step reasoning process: At 7 days a week, it takes Bert 2 * 7 = 14 days of daily crossword puzzles to use up a pencil. Since Bert does one puzzle a day, each crossword puzzle has 1050 / 14 = 75 words.
So the answer is 75.
