Math question: What is the sum of all odd numbers from 1 to 7439?

To find the sum of odd numbers up to 7439, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(2a + (n-1)d). The first term (a) is 1, the common difference (d) is 2, and the last term (l) can be calculated using l = a + (n-1)d. Solving for n, we get n = (l - a)/d + 1. Plugging the values, we find l = 7439, n ≈ (7439 - 1)/2 + 1 = 3720. Plugging these values into the formula for the sum, Sn = (3720/2)(2(1) + (3720-1)(2)) = 10,967,760. Therefore, the sum of all odd numbers from 1 to 7439 is 10,967,760.

Math Question: What is the sum of the digits in the number 7439?

To find the sum of the digits, we add the individual digits: 7 + 4 + 3 + 9 = 23. Hence, the sum of the digits in the number 7439 is 23. The sum of digits in a number is computed by separating the number into its individual digits and adding them together.

Math question: If 7439 is divided by 11 and then multiplied by 5, what is the result?

To solve this, we divide 7439 by 11, which equals 676.8181818... (rounded to 3 decimal places). Then we multiply 676.8181818... by 5, giving us 3384.0909090... (rounded to 3 decimal places). Therefore, the result of dividing 7439 by 11 and then multiplying by 5 is approximately 3384.091.
