Identify the scale factor.<br> Wingspan of airplane: 90ft<br> Wingspan of model of airplane: 6ft

Debora [2.8K]

The scale factor of the model of the airplane is 1 feet : 15 feet.

<h3>What is the scale factor?</h3>

A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension using the scale factor.

Scale factor = original dimensions / dimensions of the scale drawing

90 / 6 = 15

1 : 15

A street is drawn by dilating segment FG¯ about center A with a scale factor greater than 0 but less than 1. Is this an enlargem

Arte-miy333 [17]

Answer: This is an reduction.

Step-by-step explanation:

A dilation a king of transformation that creates an similar image (about a center of dilation) of the actual figure by changing its size with the use of a scale factor(k).

It either shrinks or stretches the image.

If |k| is greater than 1 then the image is an enlargement .
If |k| is less than 1 then the image is an reduction.
If |k| is equals to 1 then there is no change in size.

Given : A street is drawn by dilating segment $\overline{FG}$ about center A with a scale factor greater than 0 but less than 1.

Then by using (2.) , we can say that this is an reduction.
