#5)
14/4 = 3.5
24.5 / 7 = 3.5
The pair is similar and SF = 3.5
#6)
10/4 = 2.5
21/9 = 2.3333
The pair is not similar because the corresponding sides are not proportional.
Answer:

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
Step-by-step explanation:
if negative sign is there we must add and if positive sign is there subtraction should be written there.....
