Answer:
   b) 70
   c) 62
Step-by-step explanation:
Numbers are relatively prime when they have no factors in common.
__
The factors of 51 are ...
   51 = 3×17
The factors of the other numbers are ...
   84 = 2²×3×7 . . . . . has a factor of 3 in common with 51
   70 = 2×5×7 . . . . . . no factors in common
   62 = 2×31 . . . . . . . no factors in common
   30 = 2×3×5 . . . . . has a factor of 3 in common with 51
The numbers 70 and 62 are relatively prime to 51.
 
        
             
        
        
        
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is 
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so  .</u>
.</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

<em>Converting to exponential form, we have:</em>

<em>Rounding to nearest hundredth, we have:</em>
