Answer this question:In the fall, 20,000 high school students apply to Harvard University for college. In the spring, 5% of those 20,000 students are accepted to the university. Of the students who are accepted, 90% choose to attend the university, and the other 10% choose to go to other schools. How many students choose to attend Harvard University?
The number of students accepted to the university is 20,000 * 0.05 = 1,000 students. The number of students who choose to attend the university is 1,000 * 0.9 = 900 students.
The answer is 900.

Answer this question:Hunter needs to make a square patch of land whose perimeter is twice as large as a rectangular patch of land. If the rectangular patch of land has a length of 400 feet and a width of 300 feet, calculate the length of one side of the square patch of land.
If the rectangular patch of land measures 400 feet by 300 feet, the total length around it or its perimeter is given by 2 * 400 + 2 * 300 = 800 + 600 = 1400. The square patch's perimeter is double that length, so it's 1400 * 2 = 2800. Since the square has four equal sides, one side of the square patch of land will have a length of 2800 / 4 = 700 feet.
The answer is 700.

Answer this question:The height of the tree in Kilmer Park is 52 feet. Each year it grows 5 feet. In 8 years, what will the height of the tree be in inches, assuming 1 foot is 12 inches.
In 8 years, the tree will have grown 5 * 8 = 40 feet. In 8 years, the tree will be 52 + 40 = 92 feet. In 8 years, the tree will be 92 * 12 = 1104 inches.
The answer is 1104.

Answer this question:Pablo likes to put together jigsaw puzzles. He can put together an average of 100 pieces per hour. He has eight puzzles with 300 pieces each and five puzzles with 500 pieces each. If Pablo only works on puzzles for a maximum of 7 hours each day, how many days will it take him to complete all of his puzzles?

First find how many pieces are total in each puzzle. 8 puzzles * 300 pieces each = 2400 pieces. Next, 5 puzzles * 500 pieces each = 2500 pieces. All of the puzzles have 2400 pieces + 2500 pieces = 4900 pieces total. He will work a maximum of 7 hours each day * 100 pieces per hour = 700 pieces per day. So he will end up taking 4900 pieces total / 700 pieces per day = 7 days total.
The answer is 7.
