Answer:

126 tiles

Step-by-step explanation:

The while tiles are 3/4 of a foot (or 9 inches) x 9 in, so their area is 81 sq in. There are 14 blue tiles, so 14 x 81 = 1134 sq inches that need to be covered.

Each tiles is 3 x 3, so its area is 9 sq in. 1134 / 9 = 126 tiles

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per

Nikitich [7]

So we just need to plug in our values and solve
$v = 20 \sqrt{273 + t}$
we are given v is 369 so we have
$369 = 20 \sqrt{273 + x}$
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
$369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4$
so a temp of about 67 degrees C
