Question

April built a model of the F-16 Fighting Falcon that is proportional to the actual F-16 Fighting Falcon. The actual F-16 has a length of 14.8 meters and a wingspan that measures 9.8 meters. Her model has a length of 0.5 meter.

Answer 1

Answer:

The wingspan of the model is 0.33 meter.

Step-by-step explanation:

Let as assume that we need to find the wingspan of the model.

The actual F-16 has a length of 14.8 meters and a wingspan that measures 9.8 meters.

It is given that length of the model is 0.5 meter.

Let x be the wingspan of the model.

It is given that a model of the F-16 Fighting Falcon that is proportional to the actual F-16 Fighting Falcon.

$\frac{14.8}{9.8}=\frac{0.5}{x}$

On cross multiplication we get

$14.8\times x=0.5\times 9.8$

$14.8x=4.9$

Divide both sides by 14.8.

$x=\frac{4.9}{14.8}$

$x\approx 0.33$

Therefore, the wingspan of the model is 0.33 meter.

Answer 2

Length / wingspan

14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
