Questions & Answers about Math Kangaroo Sample Questions
Question 1: Solve the following problem: In a class, there are 30 students. If each student shakes hands with every other student exactly once, how many handshakes will there be in total?
Answer 1: To find the number of handshakes, we can use a combination formula. Each student needs to shake hands with every other student exactly once, so we need to choose 2 students out of 30. The formula for the number of combinations is nC2, which is calculated as n! / ((n – r)! * r!). Plugging in the values, we get 30! / ((30 – 2)! * 2!) = 30! / (28! * 2!) = (30 * 29) / 2 = 435 handshakes.
Question 2: Solve the following problem: A bookshelf contains 5 math books, 4 science books, and 3 history books. In how many ways can we arrange the books on the shelf if books of the same subject must be kept together?
Answer 2: Since the books of the same subject must be kept together, we can treat each subject as a single unit. Therefore, we have 3 units – one for math books, one for science books, and one for history books. The number of ways to arrange these units on the shelf is 3! (3 factorial), which is equal to 3 x 2 x 1 = 6. Within each unit, the books can be arranged among themselves. For math books, there are 5! ways to arrange them, for science books, there are 4! ways, and for history books, there are 3! ways. Multiplying all these possibilities together, we get 6 x 5! x 4! x 3! = 6 x 120 x 24 x 6 = 103,680 ways to arrange the books on the shelf.
Question 3: Solve the following problem: A triangle has side lengths of 6 cm, 8 cm, and 10 cm. Is this triangle a right triangle?
Answer 3: To determine if the triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. Let’s check if the given triangle satisfies this condition. The side lengths are 6 cm, 8 cm, and 10 cm. The square of 6 cm is 36, the square of 8 cm is 64, and the square of 10 cm is 100. Adding the squares of the two shorter sides, we get 36 + 64 = 100. Since the sum of the squares of the two shorter sides is equal to the square of the longest side, this triangle satisfies the Pythagorean theorem. Therefore, the triangle with side lengths 6 cm, 8 cm, and 10 cm is indeed a right triangle.
