Are the first numbers ratios?
The loudness in decibels is
L = log₁₀(I/I₀)
where
I = sound intensity, W/m^2
I₀ = reference intensity, = 10^(-12) W/m^2
Raja's power level is 10^(-7) W, therefore the decibel value is
L = 10 log₁₀(10^(-7)/10^(-12))
= 10log₁₀10^5
= 10*5
= 50 dB
Answer: 50 dB
They would have about 8 pounds of dry cat food…to be specific, 8 remainder 2
45 is 75% of what?
45 is 75% of X
Equation: Y = P% * X
Solving our equation for X
X = Y/P%
X = 45/75%
Converting percent to decimal:
p = 75%/100 = 0.75
<span>X = 45/0.75 </span>
<span>X = 60
Hope I helped!
Let me know if you need anything else!
