Can someone check my math? !
what percent of the year is each month?
100 / 12 = 8 1/3
8 x 12 = 96
1/3 x 12 = 4
96 + 4 = 100
therefore each month is 8 and 1/3 percent of a year

expression #3 is not equivalent. the others are.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
