You would use the Law of Sines here. First realize that if A and B equal 35 and 65 respectively, C=180-65-35=80°. Then from the Law of Sines:
b/sin65=15/sin80
b=15sin65/sin80
b≈13.8 units (to the nearest tenth of a unit)
M = 8.25 + 6.25 + 4(6.25)
m = 8.25 + 6.25 + 25
m = $39.50
You didn't put any options but any ratio that 4.2:1 doesn't go into is not equivalent.
Hope this helps :)
Answer:
3 Pounds for 15.10
Step-by-step explanation:
find a common multiplier (12)
4 pounds ($21.50) [×3] 12 pounds ($64.50)

you save $2.50
Answer:
The hummingbird beats its wings 86 400 times in one hour.
Step-by-step explanation:
There are 60 minutes in an hour. There are 60 seconds in a minute.
1h = 60m
= 60 × 60s
= 3600s
1s = 24 times
3600s = 24 × 3600
= 86 400 times
