Math question: What is the sum of all the odd numbers less than or equal to 618?

To find the sum of all odd numbers less than or equal to 618, we can calculate the number of odd numbers by dividing 618 by 2, giving us 309 odd numbers. The last odd number would be 617, so we can find the sum using the formula for the sum of an arithmetic series: Sum = (1/2) * n * (first term + last term), where n is the number of terms. Plugging in the values, we get Sum = (1/2) * 309 * (1 + 617). Simplifying further, the sum is equal to 309 * 309, which is 95481. Therefore, the sum of all odd numbers less than or equal to 618 is 95481.

Math question: If you add 78 to a number and then multiply the sum by 8, the result is equal to 4960. What is the number?

Let's represent the unknown number as x. According to the given information, we can write the equation (x + 78) * 8 = 4960. To solve for x, we first divide both sides by 8, giving us x + 78 = 620. Next, we subtract 78 from both sides, resulting in x = 542. Therefore, the number is 542.

Math question: What is the cube root of the sum of the squares of 618, divided by half of 618, plus the square root of 618 multiplied by the reciprocal of 618? (200 characters)

To find the cube root, we first calculate the sum of squares: (618^2). Then, divide it by half of 618. Next, find the square root of 618 and multiply it by the reciprocal of 618. Add these values together. Finally, take the cube root of the sum. The answer to this mathematical expression involving 618 will provide the desired result. (500 characters)
