Answer:
0.4 inches
Explanation:
To find out how much of the bolt sticks out the other side, we can add the thickness of both boards and then subtract this total from the length of the bolt.
Let's denote:
- Thickness of the first board as
(0.85 inches), - Thickness of the second board as
(1.25 inches), - Length of the bolt as
(2.5 inches).
The total thickness of the two boards is
.


Now, to find out how much of the bolt sticks out, subtract the total thickness from the length of the bolt:



So, 0.4 inches of the bolt sticks out the other side.
