Bobby would have bought 1.21 dollars worth of items from the school store. This because you would line up the problem. In mine, I did 21 on top, 45 in the middle, and 55 on the bottom. And then I added the 1 + 5 + 5 in the right column which equaled 11. This required me to carry the one to the other side and put the other one down in the answer. Then I did 2 + 4 + 5 + 1 = 12. Then you have to add a decimal which makes the most sense to put it in between the 1 and 2. I hope that this is a help and have a great day! If you can please mark this brainliest and contact me if you need more help!
The
equation of velocity of sound in air is v = 20 √(273 + t). In this problem, we
need to find the temperature when the velocity is 329 meters/s. You need
to measure the time it takes a sound to travel a
measured distance in order to measure its speed in air.
Given:
Velocity
of sound in air equation = v = 20 √(273 + t)
Velocity
= 329 m/s
To
solve:
V = 20 √(273 + t)
<span>
329 = 20 * sqrt(273 + t)</span>
<span>
16.45 = sqrt(273 + t)</span>
<span>
273 + t = 16.45^2</span>
<span>
t- 16.45^2-273</span>
<span>
t = -2.4 degrees Celsius</span>
<span>So, the
temperature when the velocity is 329 meters per second is -2.4 degrees Celsius.</span>
