<span>Z $ xy then Z = Kxy. When x = 2 and y = 3, and Z = 60, our constant of variation becomes
60 = K * 2 * 3
K = 10. Our constant of proportionality equals 10. We would need that in the second part of the equation.
When x = 4 and y = 9, we have
Z = 10 * 4 * 9 = 360</span>
Answer 8:3 let me know if it correct
AND SOMEONE PLEASE HELP MEEE
1 lap equals to 3 1/5 minutes what about 6 1/2 cross multiply to get 6 1/2*3 1/5 divide by 1 you get 20 4/5 translated to time is 20 minutes and 48 seconds (4/5*60=48)
20 minutes 48seconds
