Math Question: What is the result of multiplying 4491 by its digit sum, and then dividing the product by the square root of 4491?

To find the digit sum of 4491, we add the individual digits: 4 + 4 + 9 + 1 = 18. Multiplying 4491 by its digit sum gives 4491 × 18 = 80,838. Taking the square root of 4491 ≈ 67.06. Finally, divide the product by the square root: 80,838 ÷ 67.06 ≈ 1205.28. Therefore, the result is approximately 1205.28.

Math question: What is the sum of all the odd multiples of 7 less than 4491?

To find the sum of odd multiples of 7 less than 4491, we use the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where n is the number of terms. The first term can be found by dividing 4491 by 7, which is 641. Similarly, the last term can be found by finding the largest odd multiple of 7 less than 4491, which is 4489. To find the number of terms, we use the formula: n = (last term - first term)/7 + 1. Plugging in the values, we get n = (4489 - 641)/7 + 1 = 627. Using the sum formula, S = (627/2)(641 + 4489) = 313.5 * 5130 = 1,606,395. Therefore, the sum of all odd multiples of 7 less than 4491 is 1,606,395.

What is the sum of the digits of the number 4491 squared multiplied by 3, divided by 17, and rounded to the nearest whole number?

To find the sum of the digits of 4491 squared, we calculate 4491^2 = 20184481. The sum of its digits is 2 + 0 + 1 + 8 + 4 + 4 + 8 + 1 = 28. Then, multiplying this by 3, we get 28 * 3 = 84. Dividing by 17 gives us approximately 4.941. Rounding it to the nearest whole number, we obtain 5.
