I came here to see if someone had answered this question..:)
Is the secret sound the sound of someones footsteps as they walk
Sound A would be 20 dB higher than sound B. Sound intensity level (in dB) increases by 20 log (I1/I2) when the intensity ratio changes by a factor of 10. Since A is 100 times greater than B, the dB difference would be 20 log (100) = 20 dB.
A sound at 90 dB measured at a distance of 100 meters will decrease by 60 dB due to the inverse square law. Therefore, at a distance of 100 meters, the sound will be around 30 dB.
Sound travels at a speed of approximately 343 meters per second in air at room temperature. Therefore, it would take around 0.29 seconds for sound to travel 100 meters in these conditions.
A sound approximately 100 dB decibels would be similar to the noise level of a chainsaw or a rock concert. At this level, prolonged exposure can cause hearing damage.
18000 as a percentage =1800000%18000= 18000 * 100%= 1800000%
6% of 18000 = 1080= 6%/100% * 18000= 6 * 180= 1080
the percentage of 180 = 18000%180 * 100% = 18000%
% rate:= 1.80 x 100%= 180%
25% of 18000 = 18000*25/100 = 4500
It is 180.
Expressed as a percentage, 18000/15000 x 100 = 120 percent.
You could write it as 8*(18000 + 100 + 44) = 8*18000 + 8*100 + 8*44
15 percent of 18 thousand = 15/100 x 18000 = 270000/100 = 2700. Alternatively, 15/100 x 18000 = 15 x 180 (take away the 100 on the bottom of the first fraction and divide the 18000 by 100 on the top of the second fraction) = 2700.
18000
2000/18000 x 100 = 11.1%
16000 x 100 / 18000 Cancel down by '1000' Hence 16 x 100 / 18 Cancel down by '2' 8 x 100/ 9 = 800/9 88.888....%
