Question

An empty dump truck weighs about 2.8 x 10^5 pounds. How much does it weigh if 15,300 pounds of trash is added? The answer should be in scientific Notation.

a 4.33 x 10^5 pounds
b 2.953 x 10^5 pounds
c 15,302.8 pounds
d 29,530 pounds

Answer 1

To find the total weight, we need to add the weight of the empty truck and the weight of the trash added.

Weight of the empty truck = 2.8 x 10^5 pounds
Weight of the trash added = 15,300 pounds

Total weight = Weight of the empty truck + Weight of the trash added
= 2.8 x 10^5 pounds + 15,300 pounds

Adding these two weights, we get:
Total weight = 2.8 x 10^5 pounds + 15,300 pounds
= 2.8 x 10^5 + 15,300
= 2.8 x 10^5 + 1.53 x 10^4
= 2.953 x 10^5 pounds

Therefore, the answer is b) 2.953 x 10^5 pounds.
