Question

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

15,302.8 pounds

29,530 pounds

4.33×10^5 pounds

2.953×10^5 pounds

Answer 1

To find the total weight of the dump truck after adding 15,300 pounds of trash, we need to add the weight of the trash to the weight of the empty dump truck.

Weight of empty dump truck = 2.8 × 10^5 pounds

Weight of dump truck with trash = Weight of empty dump truck + Weight of trash

Weight of dump truck with trash = 2.8 × 10^5 pounds + 1.53 × 10^4 pounds

Weight of dump truck with trash = 2.8 × 10^5 pounds + 1.53 × 10^4 pounds

Weight of dump truck with trash = 4.33 × 10^5 pounds

Therefore, the weight of the dump truck after adding 15,300 pounds of trash is 4.33 × 10^5 pounds.
