Rhea is writing a paper, and she notices that she can write 1.25 pages every 2 hours.

She estimates that she can finish the six-page paper in 6 hours.

Is her estimate reasonable? Why or why not?

Rhea's estimation is unreasonable.

Step-by-step explanation:

Identify what you know:

1) Rhea calculates that she can write 1.25 pages every 2 hours

2) Rhea is calculating how long it would take her to write 6 pages.

Using Rhea's initial calculation, we can figure out roughly, how long it would take her to finish 6 pages.

First we need to divide 6 by 1.25, to figure out how many "2 hour" periods it would take Rhea.

6/1.25 = 4.8

4.8 x 2 = 9.6

It would take Rhea roughly 9.6 hours to finish 6 pages, which is 3.6 hours more than her original estimation. Thus, her estimate is unreasonable.

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'.

it is x=-4
