Question

The velocity of sound in air is given by the equation 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.
A. 507ºC
B. 6,535ºC
C. 7,081ºC
D. 67ºC

Answer 1

the equation is
v=2o square root of 273 t

Answer 2

20 sorry

Answer 3

\[v=20\sqrt{273}T\]

Answer 4

idk how to solve that equation

Answer 5

did i type it correctly?

Answer 6

yes

Answer 7

you are asked to solve for T when v=369
\[v=20\sqrt{273}T\]
divide both sides of the equation by 20 sqrt{273}
\[\frac{v}{20\sqrt{273}}=T\]
now replace v with 369

Answer 8

something is not right,
is the t meant to be inside the square root?

Answer 9

yes

Answer 10

so how do i get the degrees in celcius

Answer 11

CAN you draw the equation i still think something is missing,, like a plus or minus

Answer 12

sorry i forgot you add the t to the square root

Answer 13

\[v=20 + \sqrt{273 t}\]

Answer 14

no\[v=20\sqrt{273}+t\]

Answer 15

does that help

Answer 16

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

Answer 17

This works
