How much does the loaded truck weigh? my ans.- 3 X 10 to the 4th power= 30,000 tons or pounds i think it's tons Thank You
By the exact wording of the problem, I think you need to add 3 tons
30,000 tons +3 tons =33,000 tons
Number nine is right!!
'Cause 10 to the third power= 10x10x10 which equals 1000. Then 1000x0.5=500!
But I am not sure how many pounds is in a ton, which you would need to figure it out.
# 10 asks for the weight of the truck when loaded, (load + truck) Lance is correct
