Circle A has center of (4,5) and a radius of 3 and circle B has a center of (1,7) and a radius of 9. What steps will help show that circle A is similar to circle B?

Move the center of circle A to (1,7), then multiply its radius by 3.

Step-by-step explanation:

Moving the circles to the same center would make them concentric.  Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9.  This shows that Circle B is proportional to Circle A, thus they are similar.  

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

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
