You X to the second power.. 4 to the second power is 16 and 16-16=0 so x=4
The correct answer is 142
number of sheep= 184
ewe= 23% of total sheep
= 23/100 × 184
= 42 approximately
if number of ewe = 42
Then number of ram= ( total number of sheep - number of ewe)
= 184- 42
= 142 approximately
Therefore, number of of ram is 142

Answer:
It takes 10 years approximately for the population to reach 22,500
Step-by-step explanation:
Given:
Initial population = 8000
Population growth rate 4.5 %
Future population = 22500
To Find:
Time taken to reach a population of 22500
Solution:
The population growth can be identified by using

where
N is future popluation
is the initial population
t is the time taken
r is the rate of the growth
Here we have to find the time t, rephrasing the formula


Substituting the values we get,



t = 9.97
t=10(approx)
