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.
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 empty weight of the truck.
Empty dump truck weight: 2.8×10^5 pounds
Weight of trash added: 15,300 pounds
To add these two weights, we can simply add the numbers:
2.8×10^5 + 15,300 = 2.8×10^5 + 1.53×10^4
Now, we need to convert the second term to scientific notation with the same exponent:
1.53×10^4 = 0.153×10^5
Now, we add these two numbers:
2.8×10^5 + 0.153×10^5 = 2.953×10^5
Therefore, the total weight of the dump truck after adding 15,300 pounds of trash is approximately 2.953×10^5 pounds in scientific notation.
To find the weight of the dump truck after 15,300 pounds of trash is added, you'll need to add the weight of the trash to the weight of the empty dump truck.
First, let's express the weight of the empty dump truck in scientific notation.
The weight of the empty dump truck is given as 2.8 × 10^5 pounds.
Now, to find the weight after adding the trash, you need to add 15,300 pounds to the weight of the empty dump truck.
2.8 × 10^5 pounds + 15,300 pounds = 2.8 × 10^5 + 1.53 × 10^4 pounds
When adding numbers in scientific notation, make sure the exponents are the same. In this case, the exponents are already the same (both 5), so you simply add the coefficients:
2.8 + 1.53 = 4.33
Therefore, the weight of the dump truck after adding 15,300 pounds of trash is approximately 4.33 × 10^5 pounds.
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.
