If a construction company is building a fence that is 2/3 miles long, and they build 1/6 of the fence every hour. how many hours will it take them to complete the fence?

It takes 4 hours to complete the entire fence

Solution:

Given that construction company is building a fence that is miles long

They build of the fence every hour

To find: number of hours required to complete the fence

From given information,

Length of fence =

Time taken to build mile of fence = 1 hour

Then time taken to build 1 mile of fence = Time taken to build mile of fence divided by 1/6

Thus 6 hours are needed to build 1 mile of fence

So to build entire length of fence, time taken is given as:

time taken = total length of fence x time taken for 1 mile of fence

Thus it takes 4 hours to complete the entire fence

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'.
