I need this answered like asap now Determine whether the ratios below are proportional. What would happen if the second ratio were 15/45?
10/30, 15/20, and 7/15.

Step-by-step explanation:

Demonstrates how to check for proportionality and how to find the "mean ... A basic defining property of any proportion is that the product of the means is equal to the ... For these fractions (that is, these ratios) to be proportional (that is, for them to ... So don't worry about which fraction is "first" or "second"; either way will work.

step-by-step explanation:

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'.
