An empty dump truck weighs about 2.8 × 105 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific notation. (1 point)
O 2.953 × 105 pounds
O 4.33 × 105 pounds
O 15,302.8 pounds
O 29,530 pounds
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.
Total weight = Empty dump truck weight + Weight of trash
Total weight = 2.8 × 105 pounds + 15,300 pounds
Combining the numbers in scientific notation:
Total weight = 2.8 × 105 pounds + 1.53 × 104 pounds
Adding the numbers:
Total weight = 29.53 × 104 pounds
In scientific notation, this can be written as:
Total weight = 2.953 × 105 pounds
So, the correct answer is O 2.953 × 105 pounds.
To find the total weight of the dump truck with the added trash, you simply add the weight of the empty truck to the weight of the trash.
Empty dump truck weight = 2.8 × 10^5 pounds
Weight of trash added = 15,300 pounds
To add these weights together, we will need to convert the weight of the trash to scientific notation.
Weight of trash added in scientific notation = 1.53 × 10^4 pounds
Now we can add the weights together:
2.8 × 10^5 pounds + 1.53 × 10^4 pounds = 2.8 × 10^5 + 1.53 × 10^4
= 2.953 × 10^5 pounds
Therefore, the weight of the dump truck with 15,300 pounds of trash added is approximately 2.953 × 10^5 pounds.
So the correct answer is: O 2.953 × 10^5 pounds.
To find out how much the dump truck weighs when 15,300 pounds of trash is added, you need to add the weight of the trash to the weight of the empty dump truck.
The empty dump truck weighs 2.8 x 10^5 pounds.
To add 15,300 pounds to this, you can simply add those numbers together:
2.8 x 10^5 + 1.53 x 10^4 = 2.953 x 10^5 pounds
Therefore, the correct answer in scientific notation is:
O) 2.953 x 10^5 pounds
