Solution:
The period of a pendulum is the time of pendulum takes to swing back and forth.
Function 
Where,
L is length of pendulum in feet
T is time of pendulum in seconds
We have to calculate the time of pendulum whose length is 140 feet.
So, we substitute L=140 into formula and to solve for t
We get t,
s
Period = 13.15 s
The correct answer choice is 4
Answer:
The total number of unbroken / working slots
Step-by-step explanation:
Given that Devin's DVD case has 3 rows of slots, but 5 slots are broken
Also given that the number of slots in a row is x
1 row has x slots
3 rows has y slots
on cross multiplication we get y = 3x
ie there are a total of 3x slots in the 3 rows
Given that out of these 3x slots 5 . of the slots are broken
Therefore the total number of working slots = total number of slots - number of slots which are broken
total number of working slots are = 3x - 5
Therefore the given expression is the number of working / good slots
