i think 15 is the right answer
Answer:
30
Step-by-step explanation:
We can call the number of boys 4x and girls 6x so we can write:
4x + 6x = 50
10x = 50
x = 5, therefore the number of girls is 6x = 6 * 5 = 30.

The mass of the pendulum does not affect the period and frequency
The period can be determined using the formula:
T = 2π √(L/g)
where L is the length of the rope
and g is the acceleration due to gravity = 9.8 m/s2
Plugging in the values:
T = 2π √(5/9.8)
T = 10π/7 = 4.49 s
And for the frequency:
f = 1/T
f = 1/4.49
f = 0.22 Hz
