Math Question: What is the sum of all odd multiples of 5 between 100 and 1000, excluding multiples of 7?

To find the sum, we start by calculating the first and last odd multiples of 5 between 100 and 1000. The first odd multiple of 5 is 105, while the last is 995. To determine the number of terms, we find the common difference, which is 10. Next, the formula for finding the sum of an arithmetic series is 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. Plugging in the values, we have Sn = n/2 * (a + l) = n/2 * (105 + 995). Now we can find n by subtracting the first term from the last term and adding 1 (since it includes both endpoints): n = (995 - 105)/10 + 1 = 89. Finally, substituting n = 89, a = 105, and l = 995 into the formula, we get Sn = 89/2 * (105 + 995) = 89/2 * 1100 = 49350. The sum of all odd multiples of 5 between 100 and 1000, excluding multiples of 7, is 49350.

Math question: If the number 2245 is divided by the sum of its digits, what is the quotient obtained?

To solve this, we will first find the sum of the digits in 2245. The sum is 2 + 2 + 4 + 5 = 13. Now, dividing 2245 by 13 yields 172 as the quotient. Therefore, when 2245 is divided by the sum of its digits, the quotient obtained is 172.

Math Question: In the number 2245, if the first digit is multiplied by 100, the second digit is multiplied by 10, and the third digit is added to the result, what is the final value?

To find the final value, multiply the first digit (2) by 100, which gives 200. Then multiply the second digit (2) by 10, resulting in 20. Finally, add the third digit (4) to this result, yielding 24. Therefore, the final value is 200 + 20 + 4 = 224.
