Answer:
T = 4.0 s
Step-by-step explanation:
The period of a simple pendulum is given by

where l = length of the pendulum
= 4 m
g = acceleration due to gravity
= 9.8 m/s^2

For this case we can make the following rule of three:
38 milimeters ---------> 6 meters
57 milimeters ---------> x
Clearing x we have:
x = (57/38) * (6)
x = 9 meters
Answer:
the current length of the living room is:
x = 9 meters
4/7 = y/5019....with y being yes votes
cross multiply
(7)(y) = (4)(5019)
7y = 20076
y = 20076/7
y = 2868 <=== yes votes
total of yes and no votes : 5019 + 2868 = 7887
Yeah that’s the right answer
