Answer:
The ideal mechanical advantage (IMA) is 
.
Step-by-step explanation:
The ideal mechanical advantage is the ratio of length of longer lever 
to that of shorter lever 
IMA 
Please refer to the image attached.
We could see that the the resistance load moves 
cm towards the fulcrum so the distance of resistance load from fulcrum 
Now the as the effort force moves 
towards the fulcrum overall distance from the fulcrum to the effort force (load) 
Plugging the values of the distances in IMA formula we can have.
IMA 
.
So the IMA of the fulcrum (simple machine) 
Answer:
y=3x+12, y- intercept is 12
Step-by-step explanation:
-12x+4y=48
+12x +12x
4y=12x+48
divide by 4
y=3x+12
Answer:
67.5
Step-by-step explanation:
this gives you the basis of the problem, 2 pages every 3 minutes, so that means that you have to divide 45 by 2, this will give you 22.5
then you multiply by 3 because 22.5 is how many sets of 2 Ella has to read, and if we remember every set of 2 pages takes 3 minutes, so 22.5 times 3 is 67.5, but if you want the answer in time it would be 67 minutes and 30 seconds because a minute is 60 seconds and half of that is 30
Answer:
19 for each one
Step-by-step explanation:
Divide 57 by 3
