Question: What is the sum of the prime factors of 2845?

To find the prime factors of 2845, we start by dividing it by 2 repeatedly until we can't anymore. This leaves us with 1422 as the result. Next, we divide 1422 by 3, resulting in 474. Continuing, we divide 474 by 3, which gives us 158. Further division by 11 results in 14. Finally, dividing 14 by 2 gives us 7. Therefore, the prime factors of 2845 are 2, 3, 3, 11, and 7. Adding them together, 2 + 3 + 3 + 11 + 7 = 26. Thus, the sum of the prime factors of 2845 is 26.

Math Question: A car travels at a constant speed of 55 mph for 4 hours. How far does the car travel?

To find the distance the car travels, we multiply the speed (55 mph) by the time (4 hours). Distance = Speed × Time = 55 mph × 4 hours = 220 miles. Therefore, the car travels a distance of 220 miles in 4 hours at a constant speed of 55 mph.

What is the sum of the sequential numbers from 1 to 2845?

The sum of the sequential numbers from 1 to 2845 can be found using the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where S is the sum, n is the number of terms, and the first and last terms are 1 and 2845 respectively. In this case, n = 2845. Plugging in these values, we get S = (2845/2)(1 + 2845) = 4046775. So, the sum of the numbers from 1 to 2845 is 4,046,775.
