The speed of sound V near the Earth's surface can be represented by this equation, V=20√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.

Question

anonymous · Answer

380 = 20√t + 273 can you solve this?

anonymous · Answer

i will give you steps to solve and will be right back

minus 273 both sides
divide by 20 both sides
spare both sides

anonymous · Answer

the 273 is part of the radical... its under the line with the t

anonymous · Answer

oh i see
$$380 = 20 \sqrt{t+273}$$
 
divide by 20 both sides first then
square both sides
minus 273 both sides

ohh ok thanks :)
