0.89 Would Be 89% and 1/2 Would Be 50%
You just add up all the sides.
3.2 + 3.2 + 3.2 + 4.88 + 0.6
6.4 + 3.2 + 4.88 + 0.6
9.6 + 4.88 + 0.6
14.48 + 0.6
15.08
The perimeter is 15.08.
Hope this helps! :D
Answer:
k = 0.0916
Step-by-step explanation:
T(t) =
from question; t = 12 mins , = 50 C , = 80 C , T = 60 C
60 = 50 + (80 - 50)
60-50 = 30
10/30 = (Taking natural Log of both sides)
In(0.3333) = In
-1.0986 = -12k
k = 0.0916
Do 180 - 83 to get the measure of LWRX. then add that answer to 31. then subtract that answer from 180 and that will be your answer
