15 / 20 = 0.75. The answer is 0.75
Multiply both sides by 2pi:
F(2pi) = sqrt(g/l)
Square both sides:
F^2 (2pi)^2 = g/l
Solve for l by dividing both sides by F^2 (2pi)^2
L = g/ F^2 (2pi)^2
Simplify:
L = g / 4pi^2(f^2)
I'm not sure if you meant the tax was on the original proce or not, so here's both answers:
Tax on original price: $3010
Tax after sale: $2968
To get the amount off from the sale
3500x.2=700
3500-700=2800
To get the tax
(Tax on original price) 3500x.06=210
(Tax after sale) 2800x.06=168
Add tax onto price
(Tax on original price) 2800+210=3010
(Tax after sale) 2800+168=2968
Can you tell us the question?
