[Question]A firefighter's hose can deliver 20 gallons of water per minute. For a building fire that requires 4000 gallons of water to put out, how long will it take, in minutes, for a team of 5 firefighters, each with their own hose, to put out the fire?
[Answer]A team of 5 firefighters with hoses can deliver 5 * 20 = 100 gallons of water per minute. To deliver 4000 gallons, this team will take 4000 / 100 = 40 minutes to extinguish the fire. The answer is 40.
Q: Jerry is writing a script for a skit with three characters. The first character has eight more lines than the second character. The third character only has two lines. The second character has six more than three times the number of lines the third character has. How many lines does the first character in Jerry's skit script have?
A: The second character has 6 + 3 * 2 = 6 + 6 = 12 lines. The first character has 12 + 8 = 20 lines. The answer is 20.
Question: A pen costs $9 more than a pencil. If a pencil costs $2, find the total cost of both items.
Answer: A pen costs $9 more than $2 which is $9 + $2 = $11. Altogether they cost $11 + $2 = $13. The answer is 13.
[Question]The ratio of cows to bulls in a barn is 10:27. If there are 555 cattle on the farm, how many bulls are on the farm?
[Answer]The total ratio of cattle on the farm is 10 + 27 = 37. Since the fraction that represents bulls from the total ratio is 27 / 37, the number of bulls on the farm is 27 / 37 * 555 = 405. The answer is 405.
Q: Jerry bought 48 firecrackers for the 4th of July. A police officer discovered and confiscated 12 of them. 1/6 of the remaining ones were defective. If Jerry set off half the good firecrackers, how many firecrackers did he set off?
A: First subtract the 12 confiscated firecrackers from the original number: 48 firecrackers - 12 firecrackers = 36 firecrackers. Then multiply this number by 1 / 6 to find how many were defective: 36 firecrackers * 1 / 6 = 6 firecrackers. Then subtract the defective firecrackers to find how many were good: 36 firecrackers - 6 firecrackers = 30 firecrackers. Then divide this number in half to find how many firecrackers Jerry set off: 30 firecrackers / 2 = 15 firecrackers. The answer is 15.
Question: Jerry takes 2 antacids that weigh 2 grams each and are 5% zinc by weight. Then he takes three more smaller antacids that weigh 1 gram each and have 15% zinc. How many milligrams of zinc does he eat?
Answer:
First find the total weight of the big antacids: 2 grams / antacid * 2 antacids = 4 grams. Then convert that weight to milligrams: 4 grams * 1000 mg / gram = 4000 mg. Then multiply that number by 5% to find how much zinc is in the big antacids: 4000 mg * 5% = 200 mg. Then find the total weight of the smaller antacids in milligrams: 3 antacids * 1 gram / antacid * 1000 mg / gram = 3000 mg. Then multiply that number by the percent of zinc to find the amount of zinc in the small antacids: 3000 mg * 15% = 450 mg. Then add the zinc Jerry gets from each set of pills to find the total amount of zinc he eats: 450 mg + 200 mg = 650 mg. The answer is 650.
