What is the sum of the prime numbers between 30 and 40?

What is the sum of the prime numbers between 30 and 40?

• A. 68
• B. 60
• C. 72
• D. 74

Answer: (A)

To find the sum of the prime numbers between 30 and 40, we first need to identify which numbers in that range are prime. The prime numbers are those greater than 1 that have no positive divisors other than 1 and themselves. The prime numbers between 30 and 40 are 31, 37, and we can check for primality as follows: - **31** is only divisible by 1 and 31, so it is prime. - **32** is divisible by 1, 2, 4, 8, 16, and 32, so it is not prime. - **33** is divisible by 1, 3, 11, and 33, making it not prime. - **34** is divisible by 1, 2, 17, and 34, so it is not prime. - **35** is divisible by 1, 5, 7, and 35, thus not prime. - **36** is divisible by 1, 2, 3, 4, 6, 9, 12, 18, and 36, making it not prime. - **37** is only divisible by

The prime numbers between 30 and 40 are 31, 37, and we can check for primality as follows:

• 31 is only divisible by 1 and 31, so it is prime.

• 32 is divisible by 1, 2, 4, 8, 16, and 32, so it is not prime.

• 33 is divisible by 1, 3, 11, and 33, making it not prime.

• 34 is divisible by 1, 2, 17, and 34, so it is not prime.

• 35 is divisible by 1, 5, 7, and 35, thus not prime.

• 36 is divisible by 1, 2, 3, 4, 6, 9, 12, 18, and 36, making it not prime.

• 37 is only divisible by
