Question

The velocity of sound in air is given by the equation(posted below) where v is the velocity in meters per second and t is the temperature in degrees Celsius.Find the temperature when the velocity of sound in air is 369 meters per second. Round to the nearest degree.

Answer 1

\[369=\sqrt{273+t}\]

now try it, im going to eat, will check it when i get back

Answer 2

but how do u solve for t

Answer 3

square both sides

Answer 4

ok

Answer 5

im bout to posted how far i got

Answer 6

\[v=20\sqrt{273+t}, v/20=\sqrt{273+t}, v^2/400=273+t, v^2/400-273=t, 369^2/400-273=t\]

Answer 7

369^2/400-273=t ( this is the last one since it got cut off) but now im stuck

Answer 8

t = 67.4 or 67
