9 and a half hours. That is kind of a long time
<span>The answer is: 2. 11
Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
For this problem, we know d = 6 because (11 - 5) = (17 - 11) = (23 - 17) = 6
Now, we have to use the formula:

For this problem, d = 6 and a(base1) is 5, so plug it in like this:

To simplify, all you have to do is distribute the six and reduce like so:
So, here's your answer:
Hope this helps!
80/130 simplified would just be 8/13, and that is the simplest form.
Final answer: 8/13
Hope this helped! :)
