The price of an airline ticket from denver to washington, d. c. costs $600. a bus ticket costs $150. traveling by plane takes 6 hours compared with 51 hours by bus. other things constant, an individual would gain by choosing air travel if, and only if, his time were valued at more than

Step-by-step explanation:

Given that the price of an The price of an airline ticket from Denver to Washington, D.C. costs $600. A bus ticket costs $150. Traveling by plane takes 6 hours compared with 51 hours by bus.

Difference in time

Difference in fares

If other things remain the same the time lost is 45 hours and money diference 450 dollars

If each hour is more than dollars, he would gain by using air travel.

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

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'.
