How much louder does busy street traffic sound than a quiet radio?
It is difficult to be specific because busy street traffic and quiet radio are not standard volumes of sound.However, a quiet radio - at around a "normal" conversation level is 60 decibels (dB). A busy street is can range from the low 70 to high 80 dB. Let us say 80 dB.The difference is 20 dB = 2 Bels. This means the street is 10^2 = 100 times as loud.
What is 80 decreased by 95 percent?
To solve this, you have to start with the whole of 80, and then take away 95% of 80, or (.95 x 80). 80 - (.95) x 80 = 4 Alternatively, you could do a bit of quick mental algebra to speed it up: 80 - (.95)(80) = 1 x 80 - .95 x 80 = 80(1 - .95) = 80(.05) = 4 Since you take away 95%, you're left with 5%.
