Question

PLEASE HELP! A) 6,135º C B) 6,681º C C) 502º C D) 47º C

Answer 1

Answer: 47°C

Explanation:

Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.

`358=20√(273+t)` [divide both sides by 20]

`17.9=√(273+t)` [square both sides to cancel out square root]

`320.41=273+t` [subtract both sides by 273]

`t=47.41`

Now that we know the temperature is 47.41°C, we know our answer choice is D.
