Which of the following expresses the air temperature in terms of speed of a sound wave? Okay, so in each of the answers, they have isolated t in terms of a and the other values. So let's scroll up here and take a look at question nines information. Okay, so they say the speed of sound of a wave in air depends on the air temperature. The formula above shows the relationship between a the speed of sound in feet per second and T the air temperature in degrees Fahrenheit. Cool.

So this is the equation want to work with a is the speed of sound and T is p per second, but that doesn't really matter, because we see in the answers for nine, everything, every single answer choice has been solved for t. So all we want to do is solve for t. So how we do that, let's subtract 1052 from each side. So I have a minus 1052. And we'll divide by 1.08 divided by one point oh eight. That should be easy. Let's look at which answer gives us that. Oh, what do you look for you got a
