An empty dump truck weighs about 2.8 x 10 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific notation(1 point)
O 15,302 8 pounds
O 4.33 x 10 pounds
O 2.953 x 10 pounds
O 29 530 pounds
To find the total weight of the dump truck after 15,300 pounds of trash is added, you need to add the weight of the trash to the weight of the empty dump truck.
Empty dump truck weight: 2.8 x 10 pounds
Weight of trash added: 15,300 pounds
Total weight = Empty dump truck weight + Weight of trash added
Total weight = 2.8 x 10 pounds + 15,300 pounds
To simplify the answer in scientific notation, you can move the decimal point in the first term to the right to align it with the second term:
Total weight = 28 x 10^(0-1) pounds + 1.53 x 10^(4) pounds
Total weight = 2.8 x 10^(1) pounds + 1.53 x 10^(4) pounds
Then you can add the terms:
Total weight = 2.8 + 1.53 x 10^(4) pounds
So the answer in scientific notation is: O 2.953 x 10 pounds
