Question: If I multiply the number 1909 by 3 and then subtract the square root of 200, what is the result?

To find the result, we multiply 1909 by 3 which equals 5727. Then, we find the square root of 200, which is approximately 14.14. Subtracting this from 5727 gives us 5712.86 as the result.

Math Question: What is the sum of the first 100 odd positive integers greater than 1909?

To find the sum of the first 100 odd positive integers greater than 1909, we can use a formula. The formula for the sum of an arithmetic series is given by S = (n/2)(a + l), where S 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 a is 1911 (since it is the next odd number after 1909), and the last term l can be found using the formula l = a + (n-1)d, where d is the common difference between consecutive terms. Since we are dealing with odd numbers here, the common difference is 2. Using the formula for l, we get l = 1911 + (100-1)2 = 1911 + 198 = 2109. Now, we can substitute the values into the formula for the sum: S = (100/2)(1911 + 2109) = 50 * 4019 = 200950. Therefore, the sum of the first 100 odd positive integers greater than 1909 is 200950.

Math question: What is the sum of the digits of the product of the digits of the number 1909?

To find the sum of the digits of the product of the digits of 1909, we multiply all the digits together: 1 x 9 x 0 x 9 = 0. Thus, the product is 0. Since the sum of the digits of 0 is 0, the answer is 0.
