Question 118611
Since we have an object in centimeters, this means {{{x=25}}} (since the unit of x is in centimeters). 



{{{y=0.394x}}} Start with the given equation



{{{y=0.394(25)}}} Plug in {{{x=25}}} 



{{{y=9.85}}} Multiply 0.394 and 25 to get 9.85



So the length of the object is 9.85 inches
