Math question: What is the sum of all the even numbers from 4000 to 5000, inclusive?

To find the sum of even numbers from 4000 to 5000, we need to determine how many even numbers are between them. Dividing the difference by 2 (since the numbers are consecutive even numbers) gives (5000 - 4000) / 2 = 500. Now, we can use the formula for the sum of an arithmetic series: 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. Using a = 4000, l = 5000, and n = 500, we have Sn = (500/2) * (4000 + 5000) = 250 * 9000 = 2,250,000. Therefore, the sum of even numbers from 4000 to 5000 is 2,250,000.

Math question: What is the result of subtracting 3500 from 4000 and then dividing the result by 2?

Subtracting 3500 from 4000 yields 500. Dividing 500 by 2 gives you 250. Therefore, the answer is 250.

Math Question: How many five-digit even numbers can be formed using the digits 0, 0, 0, 4, and 6 without repetition?

To form a five-digit even number, we start by fixing the units digit, which can only be 0 or 6. We have two choices for the units digit. Next, we need to select the thousands digit, which can be any digit except 0. Hence, we have three choices for the thousands digit. For the hundreds, tens, and units digits, we can choose any digit among the remaining 3 without repetition. Therefore, applying the multiplication principle, the total number of such five-digit even numbers is 2 * 3 * 3 * 2 * 1 = 36. Hence, there are 36 different five-digit even numbers that can be formed using the digits 0, 0, 0, 4, and 6 without repetition.
