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
The weight of the empty dump truck is 2.8 × 10^5 pounds.
When 15,300 pounds of trash is added, the total weight is the sum of the empty truck weight and the weight of the trash:
2.8 × 10^5 + 1.53 × 10^4 = 2.8 × 10^5 + 1.53 × 10^4 = 2.95 × 10^5 pounds.
Therefore, the dump truck weighs 2.95 × 10^5 pounds when 15,300 pounds of trash is added.
To find the total weight of the dump truck with the added trash, you simply need to add the weight of the empty dump truck to the weight of the trash.
Empty dump truck weight: 2.8×10^5 pounds
Weight of added trash: 15,300 pounds
Adding these two weights together:
2.8×10^5 + 15,300
The sum is 2.8153×10^5 pounds.
Therefore, the dump truck weighs approximately 2.8153×10^5 pounds when 15,300 pounds of trash is added.
To find the weight of the dump truck after adding 15,300 pounds of trash, you simply need to add that weight to the weight of the empty dump truck.
Given:
Weight of empty dump truck = 2.8×10^5 pounds
Weight of trash added = 15,300 pounds
To find the total weight, add the weight of the empty dump truck and the weight of the trash added:
2.8×10^5 pounds + 15,300 pounds
To add these numbers in scientific notation, you need to ensure that both values have the same exponent.
15,300 pounds can be written in scientific notation as 1.53×10^4 pounds.
Now, you can add the values:
2.8×10^5 pounds + 1.53×10^4 pounds
To add these numbers, make sure the exponents are the same. In this case, the exponent is already the same, so you can directly add the coefficients:
2.8 + 1.53 = 4.33
Therefore, the total weight of the dump truck after adding 15,300 pounds of trash is 4.33×10^5 pounds in scientific notation.
