To find the total weight of the dump truck with 15,300 pounds of trash added, we need to add the weight of the trash to the weight of the empty dump truck.
Empty dump truck weight: 2.8×10^5 pounds
Trash weight: 15,300 pounds
Total weight = Empty dump truck weight + Trash weight
Total weight = 2.8×10^5 pounds + 15,300 pounds
To add these two values, we need to convert 15,300 pounds to scientific notation:
15,300 pounds = 1.53 × 10^4 pounds
Now we can add the values:
Total weight = (2.8 × 10^5 pounds) + (1.53 × 10^4 pounds)
Total weight = 2.8 × 10^5 + 1.53 × 10^4 pounds
Simplifying, we get:
Total weight = 4.33 × 10^5 pounds
Therefore, the answer is 4.33 × 10^5 pounds.
