question:The chicken crossed the road to get to the other side twice for the thrill of it. The first time, it had to dodge 23 speeding cars. The second time, a person tried to catch it and accidentally pulled out twice as many feathers as the number of cars the chicken had dodged. The chicken had 5263 feathers before its thrill-seeking road crossings. How many feathers did it have afterward?
answer:The chicken originally had 5263 feathers.The first time the chicken crossed the road, no feathers were pulled.The second time the chicken crossed the road, 23 * 2 = 46 feathers were pulled.The chicken thus lost 46 feathers.So the number of feathers the chicken is left with is 5263 - 46 = 5217.So the chicken has boxed{5217} feathers afterward.
question:A local aquarium has 400 goldfish, 250 guppies, and 120 angelfish. Due to a malfunction in the filtration system, the aquarium loses 15 goldfish, 10 guppies, and 8 angelfish every day. After 5 days, how many fish will be left in the aquarium?
answer:Let's calculate the total number of fish left in the aquarium after 5 days.Initial number of fish: - Goldfish: 400- Guppies: 250- Angelfish: 120Total initial number of fish = 400 + 250 + 120 = 650 + 120 = 770Daily loss of fish: - Goldfish: 15- Guppies: 10- Angelfish: 8Total daily loss of fish = 15 + 10 + 8 = 25 + 8 = 33After 5 days, the total number of fish lost = 33 * 5 = 165So, the total number of fish left after 5 days = 770 - 165 = 605Thus, the aquarium will have boxed{605} fish left after 5 days.
question:Sophia has two science tests, Biology and Chemistry, with 25 and 20 questions, respectively. She has 45 minutes to complete the Biology test and 1 hour to complete the Chemistry test. If Sophia wants to allocate the same amount of time for each question, how many more seconds can she spend on each question in the Chemistry test compared to the Biology test?
answer:To find out how many seconds Sophia can spend on each question in the Biology test, we need to calculate the total number of seconds available for the test and divide it by the number of questions.Since she has 45 minutes for the Biology test, this is equivalent to 45 * 60 = 2700 seconds.With 25 questions, this gives her 2700 / 25 = 108 seconds per question.Now we do the same calculation for the Chemistry test.Since she has 1 hour for the Chemistry test, this is equivalent to 60 * 60 = 3600 seconds.With 20 questions, this gives her 3600 / 20 = 180 seconds per question.To find out how many more seconds Sophia can spend on each question in the Chemistry test compared to the Biology test, we subtract the time per question for the Biology test from the time per question for the Chemistry test.This gives 180 - 108 = 72 seconds.So Sophia can spend boxed{72} more seconds on each question in the Chemistry test compared to the Biology test.
question:Emily purchases a monthly music subscription. The first 500 songs cost 50 and the next 500 songs cost a quarter of that amount. She shares the subscription cost equally with her two siblings. How much does Emily pay?
answer:The first 500 songs cost 50.The next 500 songs cost 50 / 4 = 12.5.So the total cost is 50 + 12.5 = 62.5.Since Emily shares this cost equally with her 2 siblings, she pays 62.5 / 3 = 20.83.Thus Emily pays boxed{20.83} dollars.
question:Emily is a 12-year-old girl. Her mother is three times her age, and her grandmother is five years older than her mother. Her aunt is half her mother's age, and her cousin is three years younger than her aunt. How old is Emily's cousin?
answer:Let's calculate the age of Emily's cousin step by step.Emily is 12 years old.Her mother is 3 times Emily's age, so her mother is 12 * 3 = 36 years old.Her grandmother is 5 years older than her mother, so her grandmother is 36 + 5 = 41 years old (but this is not needed for the problem).Her aunt is half her mother's age, so her aunt is 36 / 2 = 18 years old.Her cousin is 3 years younger than her aunt, so her cousin is 18 - 3 = 15 years old.Thus, Emily's cousin is boxed{15} years old.
question:It takes 15 minutes to assemble a bookshelf. Olivia and Ethan are assembling bookshelves, with Olivia assembling 12 bookshelves and Ethan assembling 8 more bookshelves than Olivia. Calculate the total time in minutes they took to assemble all the bookshelves.
answer:To calculate the total time Olivia and Ethan took to assemble the bookshelves, we need to calculate the number of bookshelves each of them assembled and then multiply it by the time taken to assemble each bookshelf.Olivia assembled 12 bookshelves. Ethan assembled 8 more bookshelves than Olivia, which means he assembled 12 + 8 = 20 bookshelves.Total number of bookshelves assembled is 12 + 20 = 32 bookshelves.It takes 15 minutes to assemble a bookshelf. So, the total time taken to assemble all the bookshelves is 32 * 15 = 480 minutes.Thus, Olivia and Ethan took a total of boxed{480} minutes to assemble all the bookshelves.
