Answer:
$45.50
Step-by-step explanation:
1. $65.00 ÷ 100 = 0.65
2. 0.65 x 30 = $19.50
3. $65.00 - $19.50 = $45.50
C=2pir
A=pir^2
45=pir^2
divide both sides by pi (aprox pi=3.141592)
14.32394785=r^2
sqrt both sides
3.784699176=r
sub
C=2pir
C=(2)(pi)(3.784699176)
aprox pi=3.141592
C=23.779961311m

Step-by-step explanation:
put name of triangle abc are same
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.
