Answer:
The jetski is 2.28 dB loud when the person is 41 feet away.
Step-by-step explanation:
Loudness (L) ∝ 1 / Distance² (d²)
Introduce a constant 'K'
L = K (1/d²)
L = K/d²
K = Ld²
Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud
∴ d = 8 ft , L = 60 db
K = 60(8²) = <em>3840</em>
How loud is the jetski when the person is 41 feet away?
Distance is now 41 ft
since: L = K/d²
∴ L = 3840 / 41²
L = 3840 / 1681
L = 2.28 db
<h2>Greetings!</h2><h3>1) If 7g = 315, then to get 1g you simply divide both sides by 7:</h3>
7 ÷ 7 = 1
315 ÷ 7 = 45
So g = 45
<h3> 2) If you divide 87 by h you get 4, you can simply reverse this and divide 87 by 3:</h3>
87 ÷ 3 = 29, so h is 29.
