This is a physics question.

Use the formula for simple pendulum:

T = 2π √(L/g)

Where T is the period (time to complete a full oscilation), L is the lenght and g acceleration of gravity ≈ 9.81 m/s^2 .

So, solve for l:

√(L/g) = T / (2π)

L = [T / (2π) ] ^2 * g = [ 6.0s / (2π) ]^2 * 9.81 m/s^2 = 8.9 m

Answer: 8.9 m

-15x-19=124 show how you got it please and show what to do with -15x plz!!!
Olegator [25]
You divide the 15x by the 124. I know it sounds weird because you'll get a decimal, but that is what you are supposed to do because 124 is not a factor of 5.

Three friends all have ages that are consecutive integers. The sum of their ages is 180. What is the age of the oldest friend?
Lynna [10]

Answer:

Step-by-step explanation:

Oldest friend=X+2; Middle friend=X+1; Youngest friend=X

X+(X+1)+(X+2)=180

3X+3=180 Subtract 3 from each side.

3X=177 Divide each side by 3

X=59 Youngest friend is 59.

X+2=59+2=61 ANSWER: Oldest friend is 61.

X+2=59+1=60 Middle friend is 60.

CHECK:

Sum is 180

59+60+61=180

180=180
