Answer this question:A pack of dogs found a pile of bones in the dumpster behind the butcher shop. One by one, the dogs crawled into the dumpster, grabbed a mouthful of bones, and ran off with their newfound treasure. In all, there were 5 dogs. The first dog carried off 3 bones. The second dog carried off 1 less bone than the first dog. The third dog carried off twice as many as the second dog. The fourth dog carried off one bone, and the fifth dog carried off twice the number of bones as the fourth dog carried, leaving no remaining bones in the dumpster. How many bones were in the original pile of bones?
The second dog carried off 1 less bone than the first dog, or 3 - 1 = 2 bones. The third dog carried off twice as many bones as the third dog, or 2 * 2 = 4 bones. The fifth dog carried off twice the number of bones as the fourth dog carried, or 2 * 1 = 2 bones. Therefore, the original pile of bones contained 3 + 2 + 4 + 1 + 2 = 12 bones.
The answer is 12.

Answer this question:Eastern rattlesnakes have 6 segments in their tails, while Western rattlesnakes have 8 segments. What is the percentage difference in their tail size, expressed as a percentage of the Western rattlesnake's tail size?
First find the difference in size between the two kinds of snake tail: 8 segments - 6 segments = 2 segments. Then divide that amount by the size of the Western rattlesnake's tail and multiply by 100% to express the answer as a percentage: 2 segments / 8 segments * 100% = 25%.
The answer is 25.

Answer this question:There are 60 ridges on a vinyl record. Jerry has 4 cases, each with 3 shelves that can hold 20 records each. If his shelves are 60% full, how many ridges are there on all his records?
First find the total number of records that can fit on all the shelves: 4 cases * 3 shelves / case * 20 records / shelf = 240 records. Then multiply that number by 60% to find the number of records actually on the shelves: 240 records * 60% = 144 records. Then multiply that number by 60 to find the number of ridges on all the records: 144 records * 60 ridges / record = 8640 ridges.
The answer is 8640.

Answer this question:Taro and Vlad play a video game competition together, earning 5 points for every win. After playing 30 rounds, Taro scored 4 points less than 3/5 of the total points scored. How many total points did Vlad score?
If they played 30 rounds, the total possible points from wins are 5 * 30 = 150 points. Scoring 3 / 5 of the total possible points earns you 3 / 5 * 150 points = 90 points. If Taro scored 4 points less than 3 / 5 of the total points, he scored 90 points - 4 points = 86 points. If the total points scored in the game is 150, then Vlad scored 150 points - 86 points = 64 points.
The answer is 64.
