Math question: What is the sum of the even numbers between 1958 and 2000 inclusive?

To find the sum of even numbers between 1958 and 2000, we can use the Arithmetic Progression (AP) formula: Sum = (n/2)(first term + last term), where n represents the number of terms. In this case, the first term is 1958, and the last term is 2000. Since we want the sum of even numbers, we can determine the number of terms by first calculating the number of even numbers in the range. The difference between consecutive even numbers is 2. So, the number of terms = [(last term - first term) / difference] + 1 = [(2000 - 1958) / 2] + 1 = (42/2) + 1 = 22. Plugging the values into the AP formula, the sum = (22/2)(1958 + 2000) = 11 × 3968 = 43,648. Therefore, the sum of the even numbers between 1958 and 2000 (inclusive) is 43,648.

Math Question: What is the result of dividing the square root of 1958 by the sum of all its digits multiplied by the cube root of 1958, rounded to the nearest hundredth?

To calculate the answer, we start by finding the sum of the digits in the number 1958, which is 1 + 9 + 5 + 8 = 23. Next, we compute the cube root of 1958, which is approximately 12.71 when rounded to the nearest hundredth. Taking the square root of 1958 gives us approximately 44.20. Now, we divide the square root (44.20) by the sum of the digits (23) multiplied by the cube root (12.71). So the expression becomes 44.20 / (23 * 12.71) = 44.20 / 292.33 ≈ 0.1511. Rounding this result to the nearest hundredth, we get 0.15. Therefore, the answer is approximately 0.15.

Math Question: What is the sum of all even numbers between 1958 and 2058, inclusive?

To find the sum of all even numbers between 1958 and 2058, we consider the first and last numbers: 1960 and 2058. The number of terms can be determined by subtracting the first number from the last number and adding 2 (since both endpoints are inclusive). In this case, it is (2058 - 1960) + 2 = 100 + 2 = 102. Since we are summing an arithmetic series, we can use the formula Sn = n / 2 (a + l), where Sn is the sum of the series, n is the number of terms, a is the first term, and l is the last term. The first term, a, is 1960, the last term, l, is 2058, and the number of terms, n, is 102. Plugging these values into the formula, we get Sn = 102 / 2 (1960 + 2058) = 51 * 4018 = 204,918. Therefore, the sum of all even numbers between 1958 and 2058, inclusive, is 204,918.
