Answer:
Scale Factor = 3
x=45
y=75
Step-by-step explanation:
Scale Factor = 60/20 = 3
x=15*3=45
Y=25*3=75
X=(3^4) * (2^3)
x=(81)*(8)
x= 648
Answer:
1. y=7.2
2. x=18
Step-by-step explanation:
1. Triangles CMN and CBA are similar triangles (by AAA postulate). Similar triangles have proportional corresponding sides, so

2. GK is angle G bisector. Use angle bisector's property:

If Gabrielle takes 19 minutes to run 2 miles then how much time does he take to complete 1 mile.
The above is the ‘b’ question.
We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.
In this case it would be, the mean if 2 to get 1 and the mean of 19,
The mean of 2 is,
2miles / 2 = 1 mile.
And the mean of 19 mins is,
19 mins / 2 = 9.5 mins.
Hence, Gabrielle takes 9.5 mins to complete 1 mile.
Hope this helps you. Plz let me know if you have any doubts.
