Use proportions for all of them, for #1 use the proportion 12/30 = 9/a based on corresponding sides and then cross multiply. a=22.5 For #2 use the proportion y/35 = 64/40 based on corresponding sides and then cross multiply, y=56 For #3 use the proportion 42/? = 54/36 and then cross multiply, ?=28
Answer:
distance = 585600 m
Step-by-step explanation:
change 2 hours 20 minutes to seconds
2 hrs * 60 minutes/1hr * 60 sec/min = 7200 sec
20 minutes * 60 sec/min = 120 sec
2 hr 20 min = 7320 seconds
distance = rate * time
distance = 80 m/s * 7320 s = 585600 m
Given:
To find:
The 
.
Solution:
In circle B, 
is central angle and 
is inscribed angle from two points A and C.
According to central angle theorem, central angle is always twice of inscribed angle.
[Central angle theorem]
Divide both sides by 2.
Therefore, 
.
