Q: Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?
A: In the first semester, she scored 80 + 10 = 90 marks in maths. She also scores 90 - 15 = 75 marks in arts in the first semester. She scored 1 / 3 marks less in science in the first semester than the second, which is 1 / 3 * 90 = 30. Her score in science in the first semester is 90 - 30 = 60. The total for the first semester is 90 + 75 + 60 = 225. The total for the second semester is 90 + 90 + 80 = 260. The combined marks for all the semesters in 260 + 225 = 485. The answer is 485.
Question: Uncle Lou was given four bags of peanuts to eat on his 2-hour plane flight. Each bag contains 30 peanuts. If he eats all of the peanuts during the flight, one at a time, consumed at equally spaced intervals, what is the length of time, in minutes, between eating each peanut?
Answer: Four bags of peanuts, with 30 peanuts per bag, is a total of 4 * 30 = 120 peanuts. Two hours is 60 * 2 = 120 minutes. Thus, consuming 120 peanuts, 1 at a time, at equally spaced intervals over two hours requires 120 / 120 = 1 minute intervals between peanuts. The answer is 1.
[Question]Gondor is a technician, he earns $10 from repairing a phone and $20 from repairing a laptop. If he was able to repair 3 phones last Monday, 5 phones last Tuesday, 2 laptops on Wednesday, and 4 laptops last Thursday, how much does he earn in total?
[Answer]Gondor was able to repair a total of 3 + 5 = 8 phones from Monday to Tuesday. And the total amount he earned is $10x8 = $80. He was able to repair a total of 2 + 4 = 6 laptops from Wednesday to Thursday. So, the total amount he earned is $20x6 = $120. Therefore, the total amount he earned is $120 + $80 = $200. The answer is 200.
Q: Mell went to a cafeteria to spend some time with her friends. She ordered two cups of coffee and one piece of cake. Two of her friends ordered the same, but each of them also bought a bowl of ice cream. One cup of coffee is $4, one piece of cake is $7, and a bowl of ice cream is $3. How much money did Mell and her friends need to pay at the cafeteria?
A: Mell's friends bought two bowls of ice cream, so that was a cost of 2 * 3 = $6. They all three bought two cups of coffee each, so they ordered 2 * 3 = 6 cups of coffee in total. The cost of the coffee was therefore 6 * 4 = $24. All her friends bought one piece of cake each, so the cost of it in total was 3 * 7 = $21. Mell and her friends spent in total 6 + 24 + 21 = $51 at the cafeteria. The answer is 51.
Question: 1/3 of the townspeople have received the full COVID vaccine. 1/3 are immune because they already recovered from COVID. If 1/6 of the townspeople are both vaccinated and already had COVID, what percent of the town is immune in some way?
Answer: First add the fractions of vaccinated and recovered townspeople: 1 / 3 + 1 / 3 = 2 / 3. Then you need to subtract the fraction that are both vaccinated and recovered, since they were double - counted. To do this, start by converting 2 / 3 to the same denominator as 1 / 6: 2 / 3 * 2 / 2 = 4 / 6. Then subtract 1 / 6 from 4 / 6: 4 / 6 - 1 / 6 = 3 / 6. Then divide the numerator by the denominator and multiply by 100% to express the answer as a percentage: 3 / 6 * 100% = 50%. The answer is 50.
Q: While Paul watches movies, he runs on his treadmill. He can run a mile in 12 minutes. He watches two movies, which are an average length of 1.5 hours. How many miles does he run?
A:
He runs for 3 hours because 2 x 1.5 = 3. He runs for 180 minutes because 3 x 60 = 180. He runs 15 miles because 180 / 12 = 15. The answer is 15.
