Math question: If the number 1519 is increased by its square root and then divided by its cube root, what is the result?

To find the result, we first calculate the square root of 1519, which is approximately 38.9875. Next, we find the cube root of 1519, approximately 11.8744. Adding the square root and the number, we get 1519 + 38.9875 ≈ 1557.9875. Finally, dividing this sum by the cube root, we find 1557.9875 ÷ 11.8744 ≈ 131.0895. Therefore, the result is approximately 131.0895.

Math question: What is the sum of all the odd numbers, excluding multiples of 7, between 1519 and 2021?

To find the sum, we use the arithmetic series formula. The first odd number greater than 1519 is 1521, and the last odd number before or equal to 2021 is 2021. To find the number of terms, we subtract the two endpoints and divide by 2, then add 1: (2021 - 1521) / 2 + 1 = 251 terms. The formula for the sum of an arithmetic series is 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. Substituting the values, we get S = (251/2)(1521 + 2021) = 125251. Therefore, the sum of all odd numbers between 1519 and 2021 (excluding multiples of 7) is 125251.

Math question: Find the sum of the first 100 positive odd numbers greater than 1519.

To solve this, we apply the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where Sn represents the sum, n is the number of terms, a is the first term, and l is the last term. First, we find the last term by noting that the 100th positive odd number after 1519 can be calculated as l = 1519 + (100 - 1) * 2 = 1717. Substituting these values in the formula, we get Sn = (100/2)(1519 + 1717) = 50 * 3236 = 161800. Hence, the sum of the first 100 positive odd numbers greater than 1519 is 161800.
