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)
12/5 is the answer because if you use the help of "SohCahToa" you find that 12 is the opposite side of angle A and 5 is the adjacent angle
Answer:
If the bolt is .52, it is between .517 and .583, so it can go in the package.
Step-by-step explanation:
The first step is to determine what the error amount is
6% of .55
.06*.55 =.033
The bolt must be within .033 of .55
.55 - .033 = .517
.55 + .033 = .583
The bolt must be between .517 and .583 inches
If the bolt is .52, it is between .517 and .583, so it can go in the package.
That is the pH scale
pH = - log of the concentration of hydrogen ions in a solution.
The square root of 198 is 14, so that is one side of that square. Divide by 2 to get 7 mm. B
