Math question: If 75% of a number is 6,285, what is the number?

To find the number, we set up the equation: 75% of x = 6,285. We can rewrite 75% as 0.75, so the equation becomes 0.75x = 6,285. To solve for x, we divide both sides of the equation by 0.75. Thus, x = 6,285 ÷ 0.75 = 8,380. Therefore, the number is 8,380.

Math question: What is the sum of all even numbers from 2 to 8380?

To find the sum of all even numbers from 2 to 8380, we can use the arithmetic sum formula Sn = n/2 * (a + l), where Sn 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 is 2, the last term is 8380, and the common difference is 2 since we are adding even numbers. The number of terms can be calculated as (8380 - 2)/2 + 1 = 4,189. Plugging the values into the formula, we get Sn = 4,189/2 * (2 + 8380) = 4,189/2 * 8,382 = 17,537,379. Therefore, the sum of all even numbers from 2 to 8380 is 17,537,379.

Math question: If the number 8380 is multiplied by 9 and divided by 5, what is the result?

To find the result, we multiply 8380 by 9, which equals 75420. Then, we divide 75420 by 5, yielding 15084. Therefore, after performing the given operations on the number 8380, the result is 15084.
