Math question: If I add 3 to a number and then double it, subtract 15, multiply by 7, and finally divide by 5, what will be my result?

Let's go step by step. Starting with the number 9905, we add 3 to get 9908. Doubling it gives us 19816. Subtracting 15 yields 19801. Multiplying by 7 results in 138607. Finally, dividing by 5 gives a final answer of 27721. Thus, after following these calculations, the result of the given mathematical operations starting from 9905 is 27721.

Question: What is the sum of all even numbers between 1000 and 9905, inclusive?

To find the sum of even numbers in this range, we can first find the largest even number by rounding 9905 down to the nearest even number, which is 9904. The smallest even number is 1000. Now we need to calculate how many even numbers are there between 1000 and 9904. We can subtract the smallest even number from the largest even number and add 2 to include both endpoints. (9904 - 1000) + 2 = 8904. Now, we need to find the average of these two endpoints since the numbers are evenly spaced. The average is (1000 + 9904) / 2 = 5452. Finally, we multiply the average by the number of even numbers to get the sum: 8904 * 5452 = 48,452,608. Hence, the sum of all even numbers between 1000 and 9905, inclusive, is 48,452,608.

Math Question: If three of the factors of a number 9905 are 5, 11, and 179, what is the value of the fourth factor?

To find the fourth factor, we divide the number 9905 by the product of the known factors: 9905 ÷ (5 × 11 × 179) = 17. Therefore, the fourth factor of 9905 is 17.
