Math question: Find the sum of all odd numbers between 100 and 705.

First, we calculate the sum of all odd numbers from 1 to 705. The formula for the sum of an arithmetic series is Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. The first odd number is 1, and the last odd number is 705. We can find the number of terms using the formula l = a + (n - 1)d, where d is the common difference (which is 2 for odd numbers). By substituting the values, we have 705 = 1 + (n - 1)2, which simplifies to 704 = 2n - 1. Solving for n, we get n = 353. Substituting these values into the first formula, Sn = (353/2)(1 + 705) = (353/2) x 706 = 124,819. Therefore, the sum of all odd numbers between 100 and 705 is 124,819.

Math question: What is the sum of the digits of the number obtained by multiplying 705 by twice the square root of 705 and then adding the square of 705?

To find this sum, we begin by multiplying 705 by twice the square root of 705, which yields a result. Next, we square 705, obtaining another value. Finally, adding the two obtained values will give us the desired number. We proceed to compute this sum: (705 × 2 × √705) + (705^2) = sum. Calculating each part individually: 2 × √705 = square root result. 705 × square root result = multiplication result. 705^2 = squaring result. Adding the multiplication result and squaring result: Multiplication result + Squaring result = sum. Solving this equation will yield the desired number that represents the sum of the digits of the calculated value.

Math question: The number 705 is divisible by which non-zero whole number(s) up to 200 characters long?

The number 705 is divisible by the non-zero whole numbers 1, 3, 5, 15, 47, 141, 235, and 705. When divided by each of these numbers, there is no remainder, making them factors of 705. Divisibility by 1 is trivial, and 705 divided by 3 gives the result 235. Dividing 705 by 5 results in 141 with no remainder. Further, dividing 705 by 15 gives 47, and no remainder is left. Therefore, 705 is divisible by 1, 3, 5, 15, 47, 141, 235, and 705 itself, which are all the non-zero whole number factors of 705.
