Answer:
Step-by-step explanation:
Wave velocity of the sound = frequency * wavelength.
The frequency and wavelength depend on the medium through which the sound passes and they are both greater in the guitar string than in air as the string is denser than the air. So the sound travles faster through the guitar string.
 
        
             
        
        
        
Answer:
FD ≈ 252.8 feet
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(20°) =  
tan(20°) =  
0.36397 =  
FD =  
FD = 252.77
FD ≈ 252.8 feet
 
        
             
        
        
        
1/2 divide by 5= 1/10
1/4 divide by 5=  1/20                              so    1/10 is also 2/20+1/20=3/20
so the answer is 3/20 of a pizza
 hope this helped and plz leave a thank you
