500 mm
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

## Your answer for question 9 is correct. The hand lens increased the thickness of the line 10 to the power of 3 times, so the line appeared 500 mm thick.

For question 10, the truck holds 10 to the power of 4 times more pounds than when it is empty. The empty truck weighs 3 tons. In order to find the weight of the loaded truck, you need to add the weight of the load to the weight of the empty truck. However, you mentioned that you are not sure how many pounds are in a ton.

To solve this, you need to convert tons to pounds. There are 2000 pounds in one ton. So, 3 tons would be equal to 3 x 2000 = 6000 pounds.

Now, to find the weight of the loaded truck, you need to multiply the weight of the empty truck by the factor of 10 to the power of 4 and then add the weight of the load.

Empty truck weight = 6000 pounds

Loaded truck weight = (Empty truck weight) + (Empty truck weight x 10^4)
= 6000 pounds + (6000 pounds x 10^4)
= 6000 pounds + (6000 pounds x 10000)
= 6000 pounds + 60,000,000 pounds
= 60,006,000 pounds

It seems like you provided your answer in tons instead of pounds. So, the correct answer should be 60,006,000 pounds, not 30,000 tons.

I hope this clears up any confusion. Let me know if you have any further questions!
