ivanzaharov [21]

Answer:

Canada was 418.912 sq miles smaller than the USSR.

Step-by-step explanation:

Note: I don't know if this question required a calculator so I'll answer without one.

Symbols:

  • USSR area in sq miles = u
  • Canada area in square miles = c

u<em> </em>= 8.649×106

c<em> </em>= 4.797×106

x = how much less area

u<em> </em>= c + x

  • USSR area = Canada area + number of sq miles less

Math:

u = c + x

  • plug in values

8.649×106 = 4.797×106 + x

  • divide by 106 to get rid of the ridiculously large numbers.

8.649 = 4.797 + \frac{x}{106}

  • subtract (use calculator or just traditional subtraction methods)

3.952 = \frac{x}{106}

  • multiply both sides by 106 (use calculator or traditional methods)

418.912 = x

Match the x-coordinates with their corresponding pairs of y-coordinates on the unit circle.
Sergio [31]

In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
