Answer 1

HUH?

Answer 2

What are you trying to do? You need to be more specific as to what your question is.

Answer 3

The velocity of sound in air is given by the equation v=20 sqrt273+t where v is the velocity in meters per second and t is the temperature in degrees Celsius. Find the velocity when the temperature is 117ºC. Round to the nearest meter/sec.

Answer 4

Answer 5

Well, velocity is a vector quantity and temperature is a scalar quantity so I would assume you just plug in and round...so 447 m/s

Answer 6

Tiara wants to divide a square piece of paper into two equalivalent triangles. If the square measures 20 cm on each side, what will the third side of each triangle measure?

@robtobey help

Answer 8

20sqrt(2)

Answer 9

\[20 \sqrt{273}+117\]/

Answer 10

It's geometry. If the two sides of each square are both 20cm, the third will be xsqrt2 or 20sqrt(2) cm.
