Q: Venus is at the deli to get subs for a party. She needs 81 inches of sub. The shop sells 5 and 8 inch subs. If she buys two 8 inch subs, how many 5 inch subs does she need to buy?
A: The two 8 inch subs total 16 inches because 2 x 8 = 16. She still needs 65 inches of sub because 81 - 16 = 65. She needs to buy 13 five inch subs because 65 / 5 = 13. The answer is 13.
Question: If Tony normally has a temperature of 95 degrees, and he comes down with a sickness that raises his temperature by 10 degrees, how many degrees above the threshold of fever is his temperature if a fever is anything over 100 degrees?
Answer: First, we find what Tony's temperature is by adding his normal temperature of 95 to the increase in temperature from the sickness of 10, performing 95 + 10 = 105 degrees. Since the threshold for having a fever is 100, we subtract 100 from 105 to find out the answer, performing 105 - 100 = 5 degrees above a fever. The answer is 5.
[Question]Jenna is hemming her prom dress. The dress's hem is 3 feet long. Each stitch Jenna makes is 1/4 inch long. If Jenna makes 24 stitches per minute, how many minutes does it take Jenna to hem her dress?
[Answer]First find how many inches the hem is by multiplying the length in feet by the number of inches per foot: 3 feet * 12 inches / foot = 36 inches. Then divide the length in inches by the length of each stitch to find how many stitches Jenna makes: 36 inches / .25 inches = 144 stitches. Then divide the number of stitches by Jenna's stitching rate to find how long it takes her: 144 stitches / 24 stitches / minute = 6 minutes. The answer is 6.
Q: Nancy replaced all of the old vinyl tiles in her bathroom with new hardwood flooring. She replaced flooring in two areas of the bathroom: a 10 foot by 10 foot central area, and a 6 foot by 4 foot hallway. How many square feet of hardwood flooring did Nancy install in her bathroom?
A: 10 feet by 10 feet central area is 10 * 10 = 100 square feet of space. 6 feet by 4 feet hallway is 4 * 6 - 24 square feet of space. Combined, the two areas where she replaced flooring contain 100 + 24 = 124 square feet of space. The answer is 124.
Question: Jason is tired of the neighborhood animals raiding his trash. He pepper-sprays some raccoons and 6 times as many squirrels. If he pepper-sprays 84 animals total, how many raccoons does he pepper-spray?
Answer:
Let r be the number of raccoons Jason pepper - sprays and s be the number of squirrels. We know that r + s = 84 and s = 6r. Substituting the second equation into the first equation, we get r + 6r = 84. Combining like terms, we get 7r = 84. Dividing both sides by 7, we get r = 12. The answer is 12.
