Math question: What is the result when you multiply 12 by 5 and then add 20?

To find the result, we need to multiply 12 by 5, which equals 60. Then, adding 20 to it gives us a final answer of 80. Thus, the result of multiplying 12 by 5 and adding 20 is 80.

Question: What is the sum of the first 12 odd numbers?

To find the sum of the first 12 odd numbers, we can use the arithmetic series formula 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. In this case, the first term is 1, and the last term is (2 × 12) - 1 = 23 (since the 12th odd number is 23). Plugging these values into the formula, we have Sn = (12/2)(1 + 23) = 6(24) = 144. Thus, the sum of the first 12 odd numbers is 144.

Math question: What is the sum of all even numbers between 12 and 100?

To find the sum, we can use the formula for the sum of an arithmetic series: 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. Given a = 12 and l = 100, we need to find the number of terms, n. We know that the difference between consecutive even numbers is 2. Hence, the common difference, d = 2. We can calculate n using the formula for the nth term of an arithmetic sequence: an = a + (n - 1)d. By replacing a = 12 and l = 100, we find 100 = 12 + (n - 1)2. Simplifying, we get n = 45. Now, substitute these values into the sum formula: Sn = (45/2)(12 + 100) = (45/2)(112) = 2250. Therefore, the sum of all even numbers between 12 and 100 is 2250.
