Math Question: What is the sum of the even numbers between 20 and 50, when multiplied by the difference between 7 and the square root of 9?

To find the sum of even numbers between 20 and 50, we list them as 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48. Adding these numbers, we get 440. Now, the difference between 7 and the square root of 9 is 4. Multiplying the sum of even numbers (440) by this difference (4), we get 1760. Hence, the answer is 1760.

Math question: What is the sum of the first 50 even numbers starting from 100?

To find the sum of the first 50 even numbers starting from 100, we need to find the last even number in the sequence. Since consecutive even numbers have a difference of 2, we can use the formula a_n = a_1 + (n-1)d, where a_n is the nth term, a_1 is the first term, n is the number of terms, and d is the common difference. Plugging in the values, we get a_50 = 100 + (50-1)2 = 100 + 98 = 198. Now, we can use the sum formula for an arithmetic series: S_n = (n/2)(a_1 + a_n), where S_n is the sum of the first n terms. Plugging in the values, we get S_50 = (50/2)(100 + 198) = (25)(298) = 7450. Therefore, the sum of the first 50 even numbers starting from 100 is 7450.

Math Question: If the length of each side of a square is doubled, what is the new area of the square?

To find the new area, we square the new side length. Since each side of the original square is 100 units long, when doubled, it becomes 200 units. Thus, the new area of the square is 200^2 = 40,000 square units.
