Since it's a direct relationship, whatever you change in y, you change in x. you add 1 to x to get to 9, so you'd add 1 to the y value to get y = 6
Step-by-step explanation:
v=s^3 s=3^4=81
v=(81)^3
v=531,441 cm^3
Reading - 44
Sports - 55
Video games - 55
Music - 66
--------------------------
= 220
Reading = (44/220) x 100 = 20%
Sports = (55/220) x 100 = 25%
Video games -> same as sports
Music = (66/220) x 100 = 30%
20 + 25 + 25 + 30 = 100%
hope this helps :)
plz let me know if this was not your question
