Use the formula d=rt to find the distance a long distance runner can run at a rate of 9 1/2 miles per hour for time of 1 3/4 hours.

d=rt

r = 9  1/2  as an improper fraction   (2*9 +1)/2 = 19/2

t = 1 3/4  as an improper fraction (4*1+3)/4 =7/4

d=rt

d = 19/2* 7/4 = 133/8

8 goes into 133 16 times with 5 left over

16 5/8 miles

35-60 students are taking math.

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.
