Math question: What is the sum of all the three-digit numbers that are divisible by 7 and have the digit 2 in the units place?

To find the sum, we first determine the range of three-digit numbers divisible by 7. The highest such number is 994 (142 multiples of 7 are there). From this, we remove numbers not having 2 in the units place, so 140 of them are left. Each number is repeated 10 times (i.e., 20 in the units place). Hence, the sum comes to 140 × 10 × (2 + 9 + 2 + 6) = 392,000.

Math question: What is the sum of the prime factors of 2926?

To find the prime factors of 2926, we start by dividing it by the smallest prime number, 2. We get 1463. Now, dividing 1463 by 2 is not possible, so we check the next prime number, 3. Dividing 1463 by 3 gives us 487. Continuing this process, we finally find that 487 is a prime number itself. Hence, the prime factors of 2926 are 2, 3, and 487. Now, to find the sum of these prime factors, we add them up: 2 + 3 + 487 = 492. Therefore, the sum of prime factors for 2926 is 492.

Question: If 2926 is multiplied by 7, divided by 5, then subtracted by the square root of 2926, what is the result?

To find the solution, we start by multiplying 2926 by 7, which gives us 20482. Next, we divide by 5, yielding 4096.4. Then, we calculate the square root of 2926, which is approximately 54.05. Finally, subtracting the square root from the previous result, we get approximately 4042.35. Thus, the answer is that after performing the given operations on the number 2926, the result is approximately 4042.35.
