[Question]Cooper is building a brick fence around all four sides of his property. Each of the four walls of his fence is 20 bricks long, 5 bricks high, and 2 bricks deep. How many bricks does Cooper need to complete his fence?
[Answer]A single layer of each wall requires 5 rows * 20 bricks per row = 100 bricks. As each wall has a thickness of 2 bricks, he will need 100 bricks * 2 = 200 bricks per wall. If the complete fence contains four walls, he will require a total of 200 * 4 = 800 bricks. The answer is 800.
Q: James buys 5 packs of sodas that are 12 sodas each. He had 10 sodas already. He finishes all the sodas in 1 week. How many sodas does he drink a day?
A: He bought 5 * 12 = 60 sodas. So he had 60 + 10 = 70 sodas. So he drank 70 / 7 = 10 sodas per day. The answer is 10.
Question: When Nathan is cold, he adds an extra blanket to his bed. Each blanket warms him up by 3 degrees. One night, he was cold enough that he added half of the 14 blankets in his closet on his bed. How many degrees did the blankets warm Nathan up?
Answer: Nathan added 14 / 2 = 7 blankets to his bed. The blankets warmed Nathan up 7 * 3 = 21 degrees. The answer is 21.
[Question]Archie holds the school record for most touchdown passes with 89 in a season of 16 games. Richard is close to breaking the record, having averaged 6 touchdowns a game in the first 14 games. How many touchdowns per game must he average in the final two games to beat Archie's record?
[Answer]Richard has scored 84 touchdowns because 14 x 6 = 84. To beat the record he must score 90 touchdowns because 89 + 1 = 90. He needs 6 more touchdowns to beat the record because 90 - 84 = 6. He has two games left because 16 - 14 = 2. He needs to average 3 touchdowns a game to beat the record because 6 / 2 = 3. The answer is 3.
[Question]There are ten more newborn elephants than baby hippos. If an entire herd starts with 20 elephants and 35 hippos, and the female hippos, whose number is 5/7 of the total number of hippos, give birth to 5 new baby hippos each, find the number of animals that are there altogether?
[Answer]
The total number of female hippos is 5 / 7 * 35 = 25. If each new hippo gives birth to 5 new baby hippos, the total number of baby hippos will be 5 * 25 = 125. The population of hippos after 125 new ones are born is 125 + 35 = 160. There are ten more newborn elephants than baby hippos, meaning there are 125 + 10 = 135 new baby elephants. The population of elephants is 135 + 20 = 155. Altogether, there are 155 + 160 = 315 animals. The answer is 315.
