Responses
A. 4.33 times 10 superscript 5 baseline pounds
B. 15,302.8 pounds
C. 29,530 pounds
D. 2.953×105 pounds
To find the weight of the dump truck when 15,300 pounds of trash is added, we need to add the weight of the trash to the empty weight of the truck.
Empty weight of the truck = 2.8×10^5 pounds
Weight of trash added = 15,300 pounds
Total weight = 2.8×10^5 + 15,300
Total weight = 2.8×10^5 + 1.53×10^4 (converted 15,300 to scientific notation)
Total weight = (2.8+1.53)×10^5
Total weight = 4.33×10^5
Therefore, the weight of the dump truck with 15,300 pounds of trash added is 4.33 times 10^5 pounds.
The correct answer is A. 4.33 times 10^5 pounds.
