Answer:
#9: 1.2
#10: 1.25
Step-by-step explanation:
To find the scale factor of the smaller figure to the larger figure, we're going to be dividing the measurements of corresponding edges.
[tex]\frac{larger figure}{smaller figure}[/tex]
If you wanted to find the scale factor of the larger figure to the smaller figure, you'd do: [tex]\frac{smaller figure}{larger figure}[/tex]
Question #9:
Left edges: [tex]\frac{larger figure}{smaller figure}[/tex] ⇒ [tex]\frac{24}{20}[/tex] = 1.2
Bottom edges: [tex]\frac{larger figure}{smaller figure}[/tex] ⇒ [tex]\frac{30}{25}[/tex] = 1.2
(You should get the same number as long as the figures are similar.)
Question #10:
Bottom edges: [tex]\frac{larger figure}{smaller figure}[/tex] ⇒ [tex]\frac{30}{24}[/tex] = 1.25
(There are no corresponding edges with measurements that we can compare.)
~Hope this helps!~
