Math question: What is the sum of the squares of the first 25 positive even numbers, starting from 1902?

To find the sum, we need to square each number and then add them all up. The first positive even number starting from 1902 is 1902 itself. Next is 1904, then 1906, and so on. We can notice a pattern: each subsequent number is 2 more than the previous one. So, we can use the formula for the sum of squares: n(n+1)(2n+1)/6. Here, n represents the number of terms we want to sum, which is 25. Plugging in the values: 25(25+1)(2*25+1)/6 = 25(26)(51)/6 = 21675. Therefore, the sum of the squares of the first 25 positive even numbers, starting from 1902, is 21675.

Math Question: If a company sold 1902 products in the first month, and the number of products sold increased by 8% monthly, how many products would they sell after 5 months?

To find the number of products sold after 5 months, we need to calculate the successive increase in each month. First, find the increase for one month: 1902 * 0.08 = 152.16 (rounding to 152, as it's a whole number). So, in the second month, they would sell 1902 + 152 = 2054 products. Next, let's calculate the increase for the third month: 2054 * 0.08 = 164.32 (rounding to 164). Therefore, in the third month, they would sell 2054 + 164 = 2218 products. Continue this process for the remaining two months: Fourth month: 2218 * 0.08 = 177.44 (rounding to 177). So, they would sell 2218 + 177 = 2395 products. Fifth month: 2395 * 0.08 = 191.6 (rounding to 192). Hence, in the fifth month, they would sell 2395 + 192 = 2587 products. Therefore, after 5 months, the company would sell 2587 products.

Math question: What is the product of 1902 multiplied by the sum of its digits, squared, divided by the square root of the sum of its digits multiplied by 2?

To find the product of 1902 multiplied by the sum of its digits, we first sum up the digits: 1 + 9 + 0 + 2 = 12. Now, we multiply that sum by 1902: 12 * 1902 = 22,824. Next, we square this result: 22,824^2 = 520,198,976. To calculate the sum of the digits, we add them: 1 + 9 + 0 + 2 = 12. We then find the square root of this sum: √12 = 3.4641. Finally, we multiply the square root of the digit sum by 2: 3.4641 * 2 = 6.9282. Finally, we divide the squared product by this result: 520,198,976 / 6.9282 ≈ 75,058,490. Therefore, the answer is approximately 75,058,490.
