Math question: If the number 489 is multiplied by the square root of 25, divided by 6, and then subtracted by 88, what is the result?

To solve this problem, let's break it down step by step. First, multiply 489 by the square root of 25. Since the square root of 25 is 5, the calculation becomes 489 * 5, which equals 2445. Next, divide the result by 6: 2445 / 6 ≈ 407.5. Finally, subtract 88 from the division result: 407.5 - 88 = 319.5. Therefore, the answer is 319.5.

Math question: What is the sum of the digits in the number 489?

To find the sum of the digits in the number 489, we start by breaking it down into its individual digits: 4, 8, and 9. Then, we add these digits together: 4 + 8 + 9 = 21. Therefore, the sum of the digits in the number 489 is 21.
