A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.39. So, the diameter of the tire on an actual c
Andre45 [30]
Answer: 24.96 inches.

This model car is having 1/64 scale which means the actual car is 64 times longer. To know the diameters of the actual car, you just need to divide the diameter of model car with the scale. If the diameter of the model is 0.39 inch then the calculation is:
Diameter of actual car x scale = diameter of model 
Diameter of actual car = diameter of model / scale = 0.39 inch / (1/64)=  24.96 inch.

2 The value of y is directly proportional
rusak2 [61]

Answer:

y = 17.5

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 35 when x = 140, then

35 = 140k ( divide both sides by 140 )

0.25 = k

y = 0.25x ← equation of proportion

When x = 70, then

y = 0.25 × 70 = 17.5
