Consider circle H below. Part A: If XH = 10 feet and mxy = 100°, then determine the arc length of XY. Part B: If HY = 46 inches and myX = 75°, then determine the arc length of YX. Part C: If YX = 24 meters and mYX = 120°, then determine the radius of circle H. Part D: If XY = 78 miles and mxy = 70°, then determine the radius of circle H.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
