Answer:
Step-by-step explanation:
20.1metres / seconds 
We want to convert to metres /minutes
It is known that 60seconds=1minutes
So therefore, either we multiply 20.1metres/seconds by
60seconds/1minutes 
Or
1minutes/60seconds 
Multiplying with the above does not change the magnitude of the quantity because it is like we are multiplying by 1.
Since we want to cancel seconds and it is in the denominator, so to do this we need to multiply with the fraction that has the seconds as numerator.
So, we are going to multiply with 60seconds/1minutes
20.1metres/seconds ×60seconds/minutes
1206metres/minutes.
So the correct fraction is the StartFraction 60 seconds Over 1 minute, which is the third option 
 
        
                    
             
        
        
        
No it is not a function the are two inputs for one output
        
             
        
        
        
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees. 
So your answer is 
x=72
Acute Triangle
        
                    
             
        
        
        
Answer:
p = -1  q = -4
Step-by-step explanation:
a system of eq and solve for p and q ???  can do  :)
Eq. 1)  8p + 2q = - 16
Eq. 2)  2p - q = 2
use Eq .2 and solve for q
2p - 2 = q
plug into Eq.1 with q
8p +2(2p - 2) = - 16
8p +4p -4 = -16
12p = - 12
p = -1
plug -1 into Eq. 1 for p and solve for q
8(-1) + 2q = - 16
-8 + 2q = - 16
2q = -8
q = -4
