Math question: How many even numbers are there in the range from 4000 to 5000 (inclusive) when counting by 10s?

To find the number of even numbers between 4000 and 5000 when counting by 10s, we subtract the first even number (4000, divisible by 10) and the last even number (5000, also divisible by 10) and divide by the common difference (10). First even number = 4000 Last even number = 5000 Common difference = 10 Using the formula for arithmetic sequence (an = a1 + (n-1)d), substituting the values: 5000 = 4000 + (n-1)10 Rearranging the equation: 1000 = (n-1)10 Now, isolating n: n-1 = 1000/10 n-1 = 100 n = 100 + 1 n = 101 Therefore, there are 101 even numbers between 4000 and 5000 when counting by 10s.

Question: Find the sum of all digits in the number 4831, and multiply it by the number itself, then divide the result by the product of the second and third digits, subtracting the first digit. What is the final value?

To find the sum of the digits in 4831, we have 4 + 8 + 3 + 1 = 16. Multiplying it by the number itself, we have 16 * 4831 = 77296. The product of the second (8) and third (3) digits is 24. Dividing 77296 by 24, we get 3229. Subtracting the first digit (4), we get the final value: 3229 - 4 = 3225. Therefore, the final value is 3225.

What is the product of the prime factors of the number 4831?

The prime factors of 4831 are 11 and 439. Their product is 4831 itself, since there are no other prime factors.
