Answer:
The decibel level of sound is 50dB greater on a busy street than in a quiet room where the intensity of sound is 10^-10 watt/m^2. The intensity of sound in the busy street is watt/m^2?
Step-by-step explanation:
Ok this is the best i've got.
We know that a square, by definition, has four congruent sides.
So, simply divide the perimeter by 4, and you will get the expression equivalent to each side: 12p+4/4
3p+1 is equal to one side of the square
100+2 or 50+52 these would both work
T = k/R where k is the constant of variation, T=time and R=speed.
Plug in the given values:-
12 = k/60
k = 12*60 = 720
So the equation of variation is T = 720/R
At 85 mph we have
T = 720 / 85 = 8.47 hours (answer)
