A woman was painting her nails before going out to dinner. Before she started, she realized that she could take no more than 20 minutes to finish. If it takes 0.23 minutes to paint each nail, and the paint takes 15 minutes to dry, then what is the maximum amount of nails she will be able to paint before time runs out?

13 nails (She can paint her toenails! Unless she has extra fingers o:)

Step-by-step explanation:

This is sort of funny.

20-15=5

5 minutes to paint her nails or 300 seconds

300/23=13.04

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'.

cant open file sorry!
