It rain 3.75 inches in 15 hours at the rate how much will it rain in 3.5 hours

0.87 inches (or if it meant after 3.5 more hours, 4.37 inches)

Step-by-step explanation:

15/3.5 is 4.29(rounded to the nearest hundredth)

3.75/4.29= 0.87 inches

(or if it meant after 3.5 more hours)

3.5+0.87= 4.37

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

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'.
