Square abcd and square efgh share a common center on a coordinate plane. is parallel to diagonal . across how many lines of reflection can the combined figure reflect onto itself?

4 lines of reflection can the combined figure reflect onto itself.

Step-by-step explanation:

Given Square ABCD and square EFGH share a common center on a coordinate plane and is parallel to diagonal.

We have to find that how many lines of reflection can the combined figure reflect onto itself.

Line of reflection is the line through which the figure will reflect to give a mirror image i.e the midway line between the pre-image and its image reflection.                                                                                 In the figure drawn in attachment according to given question we see that the line passes through the center of one square which is the diagonals of other square reflect the given figure onto itself.

Hence, there are 4 lines of reflection i.e 4 lines of reflection can the combined figure reflect onto itself.

i think it is c, not positive though

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
