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.
[tex]358=20\sqrt{273+t}[/tex] [divide both sides by 20]
[tex]17.9=\sqrt{273+t}[/tex] [square both sides to cancel out square root]
[tex]320.41=273+t[/tex] [subtract both sides by 273]
[tex]t=47.41[/tex]
Now that we know the temperature is 47.41°C, we know our answer choice is D.
