What is the square root of 49? Answer in simplified radical form.

The square root of 49 is 7, since 7 multiplied by itself equals 49. In simplified radical form, it can be represented as √49 = 7.

Math question: What is the sum of all odd positive integers less than or equal to 49?

To find the sum of all odd positive integers less than or equal to 49, we need to calculate the average of the first and last terms in the sequence and multiply it by the number of terms. In this case, the first term is 1 and the last term is 49. The number of odd terms is (49-1)/2 + 1 = 25. Thus, the average is (1 + 49) / 2 = 25. The sum of all odd positive integers less than or equal to 49 is 25 * 25 = 625.

Math question: What is the sum of the prime numbers between 1 and 49?

To find the sum of prime numbers between 1 and 49, first, identify the prime numbers (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47). Then, add them together: 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 + 43 + 47 = 328. Therefore, the sum of all prime numbers between 1 and 49 is 328.
