Q: There are six more white birds next to a cage than grey birds in the cage. If the number of grey birds in the cage is 40, and after ten minutes, half of the birds in the cage are freed and fly away, calculate the total number of birds remaining.
A: If the number of grey birds is 40, there are 40 + 6 = 46 white birds near the cage. When half of the grey birds fly away, the number that remains is 1 / 2 * 40 = 20. The total number of birds is 20 + 46 = 66 in and next to the cage. The answer is 66.
Question: Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
Answer: There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.
[Question]From March to August, Sam made $460 doing 23 hours of yard work. However, from September to February, Sam was only able to work for 8 hours. If Sam is saving up to buy a video game console that costs $600 and has already spent $340 to fix his car, how many more hours does he need to work before he can buy the video game console?
[Answer]Sam makes $460 / 23 hrs = $20 / hr. From September to February, Sam made 8hrs x $20 / hr = $160. From March to February, Sam made a total of $460 + $160 = $620. After fixing his car, he was left with $620 - $340 = $280. Sam needs another $600 - $280 = $320. Sam needs to work another $320 / $20 / hr = 16 hours. The answer is 16.
Q: Alyssa, Keely, and Kendall ordered 100 chicken nuggets from a fast-food restaurant. Keely and Kendall each ate twice as many as Alyssa. How many did Alyssa eat?
A: To figure out this problem we need to turn it into an equation. Let's make A the number of nuggets Alyssa ate. We know all three girls ate 100 nuggets total, so 100 nuggets = A (how many Alyssa ate) + 2A (how many Keely ate) + 3A (how many Kendall ate) or 100 = A + 2A + 3A which is 100 = 5A. Then we will divide each side by 5 to figure out how many nuggets Alyssa ate, 100 / 5 = 5A / 5 or 20 = A. The answer is 20.
Question: Thor is 13 times older than Captain America. Captain America is 7 times older than Peter Parker, and Ironman is 32 years older than Peter Parker. How old is Ironman if Thor is 1456 years old?
Answer: Captain America is 1456 / 13 = 112 years old. Peter Parker is 112 / 7 = 16 years old. Ironman is 16 + 32 = 48 years old. The answer is 48.
Q: Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days?
A:
On Tuesday, Oliver worked out for 4 - 2 = 2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = 8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = 4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = 18 hours. The answer is 18.
