Question

"!I NEED HELP WITH MY MATH PROBLEMS, PLEASE!" (27 POINTS)

25.) You ride your bike at an average speed of 14 miles per hour. The number of miles m you ride during h hours is modeled by m = 14h.

26.) The circumference C of a circle and its diameter d are related by the equation C = (pie sign) d.

(THE PICTURE HAS THE SAME QUESTIONS, ONLY 25, AND 26.)

Answer 1

25. m = 14h (True)
26. Since circumference of circle is 2πr then it is right to say it is also equal to πd because:

2r = d
therefore 2πr = πd which is the circumference of the circle

Answer 2

25. yes it's direct variation
26. yes
