It is estimated that there are 828 motor vehicles in the US for every 1,000 people. If the number of motor vehicles in the US is 260 million, then what is its population to the nearest million? A) 215 million
B) 314 million
C) 315 million
D) 475 million

B) 314 million

Step-by-step explanation:

Given the following data;

Estimated motor vehicles = 828

Total number of motor vehicles = 260,000,000

Also, for 1,000 people, there are 828 motor vehicles.

Therefore, to find the population;

Population = 314,009,662

Therefore, the population to the nearest millions is 314,000,000 people.

Method II

Motor vehicles = population

828 vehicles = 1000 people

260,000,000 vehicles = X people

Cross multiplying, we have;

828X = 260,000,000,000

X = 314,009,662

Therefore, the population to the nearest millions is 314,000,000 people.

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'.
