To find the total weight of the dump truck after adding 15,300 pounds of trash, you would add the weight of the empty dump truck (2.8×10^5 pounds) to the weight of the trash (15,300 pounds).
2.8×10^5 + 15,300 = 2.8153×10^5 pounds
Therefore, the answer in scientific notation is 2.8153×10^5 pounds.
To calculate the 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.
The weight of the empty dump truck is given as 2.8×10^5 pounds.
Adding 15,300 pounds of trash to this weight gives:
2.8×10^5 + 15,300 = 2.8×10^5 + 1.53×10^4
To add these numbers in scientific notation, we need to ensure that the exponents are the same. In this case, we can rewrite 1.53×10^4 as 0.153×10^5.
Now, we can add the numbers:
2.8×10^5 + 0.153×10^5 = 2.953×10^5
Therefore, the weight of the dump truck with 15,300 pounds of trash added is 2.953×10^5 pounds.
To find out how much the dump truck weighs when 15,300 pounds of trash is added, we need to add the weight of the trash to the weight of the empty dump truck.
The weight of an empty dump truck is given as 2.8×10^5 pounds.
To add the weight of the trash, you simply add 15,300 pounds to the weight of the empty dump truck.
So, the weight of the dump truck with the trash added is:
2.8×10^5 + 15,300 = 2.8×10^5 + 1.53×10^4 = 2.953×10^5 pounds.
Therefore, the correct answer is 2.953×10^5 pounds.
