Answer:
Step-by-step explanation:
You know that anything to the zeroeth power is 1, so the equation is now
-7 * 1, or -7.
 
        
             
        
        
        
So there are 8 counters out of 20 which are yellow. so that is 8/20 which is simplified to 2/5
so the answer is 2/5
        
                    
             
        
        
        
Answer:
6300
Step-by-step explanation:
253 is closer to 300 than to 200 
 
        
                    
             
        
        
        
Initial speed of the skateboard (u) = 0 m/s (Starts from rest)
Acceleration of the skateboard (a) = 2 m/s²
Time taken by the skateboard (t) = 2s
By using equation of motion, we get:

 Final speed of the skateboard(v) = 4 m/s
 Final speed of the skateboard(v) = 4 m/s
