Answer:
C) 171.40
Step-by-step explanation:
The formula to find the volume of a rectangular prism is:
l x w x h = V
Substitute values:
4.2 x 5.3 x 7.7 = 171.40
So, there's your answer!
 
        
                    
             
        
        
        
Answer:
375 adult tickets and 302 student tickets
Step-by-step explanation:
s+a=677
a=s+73
s+s+73=677
2s+73=677
2s=604
s=302
a= 375
 
        
             
        
        
        
Answer:
cos(x-30)=1/2
Step-by-step explanation:
We use the following relationship to obtain cos(x)

From that, we have that cos(x)= sqrt(1-1/4)=sqrt(3) / 4
To obtain the value of cos(x-30), lets remember the following expression:

Therefor, we can use that to obtain our desired function cos(x-30)
cos(x)*cos(30)+sin(x)*sin(30)

=2/4=1/2
