Granny Smith, who was leaving Montreal, boarded a train at four minutes past the hour. After boarding, she stuck her head out of the window and shouted to the ticket man, "How far are we from Toronto?" "All trains take five hours either way," he replied. "How many trains shall I meet on the way?" asked Granny. "A train leaves Toronto at five minutes past the hour, every hour," Answered the ticket men. How many trains will Granny Smith meet?

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

answer: 0.64

step-by-step explanation:

i think its 7.6

if so your welcome

a≈380.13mi² would be your answer if the radius was 11 miles
