Darla measured the length of 4 ants in science class they were 1/2 inch 3/5 inch,1/4 inch and 3/10 inch long. what is the difference between the two shortest ants and the two longest ants?

Convert them to have the same denominator then subtract

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.
