Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles
Hope this helps
Answer:
what grade are u in
Step-by-step explanation:
bc I have no idea what u are doing
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 4

I hope this helps! Have a good day!
You didn't include the formula.
Given that there is no data about the mass, I will suppose that the formula is that of the simple pendulum (which is only valid if the mass is negligible).
Any way my idea is to teach you how to use the formula and you can apply the procedure to the real formula that the problem incorporates.
Simple pendulum formula:
Period = 2π √(L/g)
Square both sides
Period^2 = (2π)^2 L/g
L = [Period / 2π)^2 * g
Period = 3.1 s
2π ≈ 6.28
g ≈ 10 m/s^2
L = [3.1s/6.28]^2 * 10m/s^2 =2.43 m
Hope this helps you!!!!
