On a tractor, the diameter of the large tire is 5 feet and the diameter of the small tire is 3 feet 9 inches. A toy tractor is made to scale from the actual tractor. On the toy tractor, the diameter of the large tire is 8 inches
What is the diameter in inches of the small tire on the toy tractor?

small tire on the toy model= 6 inches

convert 5 feet to inches

5ft= 60in

proportion of the big tires is 60:8 or 15:2

the small tire on the toy model is unknown but the small tires on the actual model is 3ft and 9 in

convert that to inches as well

3ft and 9in= 45 inches

45÷15= 3 (this is to see how many times the x (15) increases so that we can equally increase the y value

3x2= 6

hope this helped!

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

it has the same slope and a different y-intercept

hope this : )
