Math question: What is the sum of all odd numbers between 1 and 7922?

To find the sum of odd numbers between 1 and 7922, we can use the formula Sn = n/2 * (first term + last term), where n is the number of terms. In this case, the first term is 1, the last term is 7921, and the common difference is 2. First, let's find the number of terms. The formula for finding the nth term of an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, and d is the common difference. We need to solve for n in the equation 7921 = 1 + (n - 1)2. Simplifying, we get 7920 = 2n - 1, which gives n = 3961. Now we can calculate the sum using the formula: Sn = 3961/2 * (1 + 7921) = 3961/2 * 7922 = 15,678,611. Therefore, the sum of all odd numbers between 1 and 7922 is 15,678,611.

Math Question: If each digit of the number 7922 is multiplied by its respective place value and then added together, what is the sum?

To find the sum, we multiply 7 by 1000, 9 by 100, 2 by 10, and 2 by 1, resulting in 7000 + 900 + 20 + 2 = 7922. Therefore, the sum of the digits in the number 7922 is 7922.

Question: What is the square root of the sum of the factors of 7922, rounded to the nearest whole number?

To find the factors of 7922, we first prime factorize it: 2 × 7 × 11 × 49. Now, the factors are 1, 2, 7, 11, 14, 22, 49, 77, 98, 154, 539, 847, 1078, 1694, 5939, and 7922. The sum of these factors is 19339. Taking the square root of 19339 gives us approximately 139.10. Since we need the whole number closest to this value, the answer is 139.
