Find the length of the model. Then find the scale factor. The length of the actual bird is shown.
Actual length of bird: 5 7/8
ratio: 1in = 0.5 in

The length of the model is 11.75 or inches

The scale factor is

Step-by-step explanation:

Given data:

Actual length of bird:

Ratio: 1 in = 0.5 in

From this, it is clearly showed that the length of the model would be twice that of the length of original bird. The ratio of two corresponding lengths in two comparable geometric shapes is called a scale factor. Therefore, scale factor can find by,

scale factor:

To find the length of the model, the equation can be framed as below,

        0.5 x  = 5.875

          or inches

based on context clues you gave i'm assuming the answer would be c.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
