The intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²
Decibel level, dB = 10log₁₀(I/I₀) where dB = decibel level = 156, I = intensity at 156 dB and I₀ = 10⁻¹² W/m².
Since we require I, making I subject of the formula, we have
dB/10 = log₁₀(I/I₀)
Substituting the values of the variables into the equation, we have
I = 3981.072W/m²
I = 3.981 × 10³ W/m²
So, the intensity of sound which the decibel level of the sound measures 156 is 3.981 × 10³ W/m²

Answer:
254.47 to the nearest tenth is 254.5mm
Step-by-step explanation:
Hey! here's explanation:
A= π x r^2 (squared)
so A = π x 9mm^2
which gives you the answer of 254.47
TO THE NEAREST TENTH IS 254.5!

Answer:
y=45-3x, where x=# of days, y=number of hours left, and 45=total # of hours.
Step-by-step explanation:
hours left= total - hours/day
we want y, so:
y=45-3x is the right answer
