What is the sum of the digits in the number 4891 when multiplied by 3, then divided by 2, and finally subtracting 100 from the result?

The sum of the digits in 4891 is 4 + 8 + 9 + 1 = 22. When multiplied by 3, we get 66. Dividing 66 by 2 gives us 33. Finally, subtracting 100 from 33 gives us -67.

Math question: What is the sum of the digits in the number 4891?

To find the sum of the digits in 4891, we add up each digit individually: 4 + 8 + 9 + 1 = 22. Thus, the sum of the digits in 4891 is 22.

Question: What is the sum of the digits of the number 4891, multiplied by the square root of its reversed three-digit number?

To find the sum of the digits of 4891, we add 4+8+9+1, which equals 22. Now, let's determine the reverse of the three-digit number 489. It becomes 984. Taking the square root of 984, we get approximately 31.352. Multiplying this square root by the sum of the digits (22), we obtain 22 * 31.352 ≈ 689.744. Therefore, the answer is 689.744.
