Answer: Approximately 25187 animals of this species will be left in 2025
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as 
y = b(1 - r)^x
Where
y represents the population of animals after x years.
x represents the number of years.
b represents the initial population of animals.
r represents rate of decay.
From the information given,
b = 200000
r = 4.5% = 4.5/100 = 0.045
x = 2025 - 1980 = 45 years
Therefore,
y = 200000(1 - 0.045)^45
y = 200000(0.955)^45
y = 25187
 
        
                    
             
        
        
        
Answer:
N0 solution.
Step-by-step explanation:
x=-2y+1....(1)
x+2y=9....(2)
put equation (2) to equation (1)
-2y+1 + 2y=9
combine
-2y + 2y=9-1
0=8 
No solution.

Third angle = 180 - (44 + 72) = 180 -  116 = 64 degrees answer
        
             
        
        
        
Is it any fraction? if so 6/16 and 2/8 are equivalent
