[Answer]Kenneth has 7 x 3 = 21 fish in his aquarium. Matthias has 21 - 15 = 6 fish in his aquarium. In total, the boys have 7 + 21 + 6 = 34 fish. The answer is 34.
Q: Christy and her friend Tanya go to Target to buy some face moisturizer and body lotions. Christy spends twice as much as Tanya, who pays 50$ for two face moisturizers each and 60$ per body lotion, buying four of them. How much money did they spend together in total?
A: The total amount Tanya spent on face moisturizers is 50 * 2 = $100. If she bought four body lotions, the total cost is 4 * 60 = $240. Tanya spent a total of 240 + 100 = $340 in the store. If Christy spent twice this amount, the total was 2 * 340 = $ 680. The total amount of money they both spent is 680 + 340 = 1020$. The answer is 1020.
Question: Kevin has been for a run and wants to calculate how far he traveled. He ran at 10 miles per hour for half an hour, 20 miles per hour for half an hour, then ran at 8 miles per hour for 15 minutes. How many miles has Kevin run?
Answer: At his first speed, Kevin ran 10 miles per hour * 0.5 hours = 5 miles. At his second speed, he ran 20 miles per hour * 0.5 hours = 10 miles. 15 minutes is a quarter of an hour so at his third speed, he ran 8 miles per hour * 0.25 hours = 2 miles. Therefore, Kevin ran a total of 5 miles + 10 miles + 2 miles = 17 miles. The answer is 17.
[Question]A pole is 20 meters long. It got cut in a way that left it 30% shorter. How long is the pole?
[Answer]The cut - away part of the pole is 30 / 100 * 20 = 6 meters long. So the pole is left at the length of 20 - 6 = 14 meters. The answer is 14.
Q: While preparing balloons for Eva's birthday party, her mom bought 50 balloons and 1800cm³ of helium. One balloon needs 50cm³ to float high enough to touch the ceiling, and she can fill any remaining balloon with ordinary air. If she used up all of the helium and inflated every balloon, how many more balloons are touching the ceiling than not?
A: 50cm³ will make one balloon touch the ceiling so 1800cm³ will make 1800 / 50 = 36 balloons touch the ceiling. There are 50 balloons in total so 50 - 36 = 14 balloons will not float since they were filled with ordinary air. There are 36 - 14 = 22 more balloons touching the ceiling than not. The answer is 22.
Question: The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left?
Answer:
For the first 30 minutes, 3 * 2 = 6 cups of water came out. For the next 30 minutes, 3 * 2 = 6 cups of water came out. For the next hour, 6 * 4 = 24 cups of water came out. A total of 6 + 6 + 24 = 36 cups of water came out. Shawn had to dump water which left 36 / 2 = 18 cups of water. The answer is 18.
