Answer 1

Hello!

To find how much was removed, we will subtract our original width and subtract the new width from it.

2.342-2.087=0.255

Therefore, our answer is B) 0.255

I hope this helps!

Answer 2

Thickness of the plate before polishing = 2.342
Thickness of the plate after polishing. = 2.087
How much was removed = 2.342- 2.087 = 0.255
Hence , the answer 0.255 which is option B
