An empty dump truck weighs about 2.8×10^5 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific notation.

Answer 1

To find the total weight of the dump truck after adding trash, we need to add the weight of the empty dump truck and the weight of the trash.

The weight of the empty dump truck is 2.8×10^5 pounds.

The weight of the trash being added is 15,300 pounds.

Therefore, the total weight of the dump truck after adding trash is 2.8×10^5 + 15,300 = 2.8153×10^5 pounds.

The answer in scientific notation is 2.8153×10^5 pounds.
