Math question: What is the sum of the first 10 multiples of 120 greater than 2000?

To find the sum, we need to calculate 1200 x 11 + 1200 x 12 + 1200 x 13 + ... + 1200 x 20. This simplifies to 13,200 + 14,400 + 15,600 + ... + 24,000. Using the formula for the sum of an arithmetic series, S = n/2(a+l), where n is the number of terms, a is the first term, and l is the last term, we can substitute in the appropriate values. In this case, n = 10, a = 13200, and l = 24000. Plugging these values into the formula, we get S = (10/2)(13200 + 24000), which simplifies to S = 5(37200), equaling 186,000. Therefore, the sum of the first 10 multiples of 120 greater than 2000 is 186,000.

Math question: What is the sum of all odd numbers less than 1200 that are divisible by 5?

To find the sum of odd numbers less than 1200 divisible by 5, we first determine the highest odd number under 1200 divisible by 5. If we divide 1200 by 5, the highest multiple of 5 before 1200 is 1195, which is an odd number. Next, we calculate the number of terms in this arithmetic sequence: (1195 - 5) / 10 + 1 = 120. Here, we subtract 5 since 1195 is already counted in the sequence, divide by the common difference 10, and add 1 to include both the first and last term. Now, using the formula for the sum of an arithmetic sequence: (120/2)(first term + last term) = (120/2)(5 + 1195) = 60 * 1200 = 72000. Therefore, the sum of odd numbers less than 1200 divisible by 5 is 72,000.

Math question: What is the largest prime factor of 1200?

To find the largest prime factor of 1200, we can begin by finding the factors of 1200: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 400, 600, 1200. Now, let's check each factor for prime factorization. The prime factorization of 1200 is 2^4 * 3 * 5^2. Therefore, the largest prime factor of 1200 is 5.
