I came here to see if someone had answered this question..:)
The ear drums feel the sound pressure difference of the factor 100; that is 20 log 100 = 40 dB. The microphone at a sound pressure level meter (SPL) can measure that.
Is the secret sound the sound of someones footsteps as they walk
100 times intensity.
(90 dB - 70 dB) = 20 dB = 100 times as much sound power.(100 times 'as much' = 99 times 'more')
10 times.
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%
180 meters = 18000 centimeters180 meters = 180 meters * 100 cm/1 meter = 18000 cm
