Atoy train car is 6 in. long. if a real train car is 75 ft long, which of the following have the same constant of proportionality as the toy train car to the real train car?

A toy train and a real train are similar shapes, then their dimensions are proportional.

Step-by-step explanation:

if there is a multiple choise then it's (c and d)

C. Ms. Gomez's house is 37.5ft tall and a toy house is 3 in. tall.

D. A real trailer is 50 ft long and a toy trailer is 4 in. long.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
