Answer:
(4, -6)
Step-by-step explanation:
(x1+x2)/2 + (y1+y2)/2 = midpoint 
(11+-3)/2 = 8/2 = 4.     x = 4
(-5 + -7)/2 = -12/2.      y = -6 
4, -6 is the midpoint

Answer:
Step-by-step explanation:
It depends on whether the 30 cm side is the hypotenuse, or one of the legs. 
If the 30 cm side is the hypotenuse, then the third side is √(30^2-10^2) = √800 = 20√2 cm
If the 30 cm side is one of the legs, then the hypotenuse is √(30^2+10^2) = √1,000 = 10√10 cm
 
        
             
        
        
        
We know, 
    1 MB = 1000 KB
513 MB = (1,000 * 513) KB
             = 513,000 KB
Now,
          1 KB = 1,000 bytes
513,000 KB = (1,000 * 513,000) bytes
                   = 513,000,000 bytes 
∴ 513 MB is 513,000,000 bytes
        
             
        
        
        
The answer is 6 . Why because 6 -12 =-6
The answer fir the second question mark is -22 . Why because -10-12 =-22
