Answer:
Scale factor = 1/2, New screen 46 in by 38 in.
Step-by-step explanation:
The dimensions of screen is 92 in. by 76 in.
It has a feature that splits the screen to allow you to watch 4 channels at once as shown in the below figure.
All four parts are equal.
Let the dimensions of new screen be x in. by y in.
[tex]2x=92[/tex] and [tex]2y=76[/tex]
Divide both sides by 2.
[tex]x=46[/tex] and [tex]y=38[/tex]
Scale factor is
[tex]\text{Scale factor}=\frac{\text{New dimension}}{\text{Corresponding original dimension}}[/tex]
[tex]\text{Scale factor}=\frac{46}{92}[/tex]
[tex]\text{Scale factor}=\frac{1}{2}[/tex]
Therefore, the scale factor is 1/2.
