[Question]Yanni has 5 paintings that combined, take up 200 square feet. 3 of the paintings are 5 feet by 5 feet. 1 painting is 10 feet by 8 feet. If the final painting is 5 feet tall, how wide is it?
[Answer]Each 5 by 5 painting is 25 square feet because 5 x 5 = 25. All three of them take up 75 square feet because 3 x 25 = 75. The 10 by 8 painting takes up 80 square feet because 10 x 8 = 80. These four paintings take up 155 square feet because 80 + 75 = 155. The final painting is 45 square feet because 200 - 155 = 45. If it is 5 feet wide it is 9 feet tall because 45 / 5 = 9. The answer is 9.
Q: A group of 30 tourists sets out on a walking tour of the rainforest. Two tourists are eaten by anacondas, then half the remaining tourists try to pet poisonous dart frogs and get poisoned. If only 1/7 of the poisoned tourists recovered, how many tourists are left at the end of the tour?
A: First, subtract the two tourists the anacondas got from the initial 30 tourists: 30 - 2 = 28. Next, divide 28 by two to find out how many tourists got poisoned: 28 / 2 = 14. Now figure out how many of the 14 poisoned tourists recovered: 14 / 7 = 2. The total number of surviving tourists is 14 + 2 = 16. The answer is 16.
Question: Steve is holding nickels and dimes in his hand. He has 4 more dimes than nickels. He has a total of 70 cents in his hand. How many nickels is he holding?
Answer: Let x be the number of nickels he is holding. His nickels are worth 5 * x = 5x cents. He has x + 4 dimes. The dimes are worth 10 * (x + 4). The total worth of the nickels and dimes is 5x + 10 * (x + 4) = 70. 5x + 10x + 40 = 70. 15x = 30. x = 2, Steve has 2 nickels in his hand. The answer is 2.
[Question]Bill needs to soak his clothes for 4 minutes to get rid of each grass stain and 7 additional minutes to get rid of each marinara stain. If his clothes have 3 grass stains and 1 marinara stain, how long does he need to soak them?
[Answer]First find the total soaking time to get rid of the grass stains: 4 minutes / stain * 3 stains = 12 minutes. Then add the soak time for the marinara to find the total soak time: 12 minutes + 7 minutes = 19 minutes. The answer is 19.
