Just follow step by step. Follow PEMDAS (Parentheses, Exponents. Multiply/Divide, Add/Subtract)
$600 because you must multiply. 150/ (25/100)... 1,500/25= 600
70dB is represented by 100cars in 60sec. Therefore if the number of cats is reduced by 3/4 in the same amount of time(60s), then the decibel level will reduce by 3/4 also. So 70dB * .25= 17.5dB
The distance between A and B = |B - A|
We have -12 and -1.
Substitute:
|-1 - (-12)| = |-1 + 12| = |11| = 11
<h3>Answer: 11 units.</h3>
A: 3.2/294=12/T
<span>T=1102.5 K </span>

<span>c. </span>
<span>pV/T </span>
<span>1.1*V/294 = 12*15000/1088 </span>
<span>V= 48.64 m^3</span>
