4.33×105 pounds
4.33 times 10 superscript 5 baseline pounds
15,302.8 pounds
15,302.8 pounds
29,530 pounds
The answer is 2.953 × 10^5 pounds.
To find the weight of the dump truck after 15,300 pounds of trash is added, we need to add the weight of the trash to the empty weight of the truck.
Empty dump truck weight: 2.8×10^5 pounds
Trash weight: 15,300 pounds
The total weight would be:
2.8×10^5 pounds + 15,300 pounds = 2.953×10^5 pounds
So, the weight of the dump truck after adding 15,300 pounds of trash is 2.953×10^5 pounds.
To find the weight of the dump truck after adding 15,300 pounds of trash, we can simply add the given weight of the empty dump truck to the weight of the trash.
The weight of the empty dump truck is given as 2.8×10^5 pounds in scientific notation. We can rewrite this as 280,000 pounds.
Adding 15,300 pounds of trash to this, we get:
280,000 + 15,300 = 295,300 pounds
Now, we can express this answer in scientific notation.
295,300 pounds can be written as 2.953×10^5 pounds.
So the correct answer is:
2.953×10^5 pounds.
