Question

The speed of sound V near the Earth's surface can be represented by this equation V=20 radical t+273, where t is the temperature in degrees Celsius. Find the temperature when V=380 meters per second. Round to the nearest whole number.

give me one sec and i will show you my problem

Answer 1

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

Answer 2

\[380=20\sqrt{(t+273)}\]
\[19=\sqrt{(t+273)}\]
\[19^{2}=(t+273)\]
361-273= t
t = 88 C

Answer 3

got the same
