Answer:
the value of y = 781.25
Step-by-step explanation:
In variation
if there is inverse relation between two variables, then if one variable increases then another variable decreases in same proportion.
Any variation be it direct or inverse between two variable say and y can be represented by
y = kx where k is constant of proportionality
Given
y = 6.25 and x = 0.16
lets use this value in y - kx to find k
6.25 = k*0.16
k = 6.25/0.16 = 39.0625
Now the
relation ship etablished is
y = 39.0625x
given x = 20
then
y = 39.0625*20 = 781.25
the value of y when x = 20 is 781.25
