Question

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

Answer 1

Answer: 47°C

Step-by-step explanation:

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

$358=20\sqrt{273+t}$                    [divide both sides by 20]

$17.9=\sqrt{273+t}$                        [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.
