Step-by-step explanation:

12-8 is 4 and 3/4 is 75% if that is what youre asking but specify
Answer: 2%
Step-by-step explanation:
1600/80000. Simplifying by 100:
16/800. Simplifying by 8, comes to:
2/100 = 2%
Answer:
1. f(0) = 501170
2. decreasing
3. 2% decrease
4. 302438
Step-by-step explanation:
In 1995 x=0
f(x) = 501170(0.98)^0
f(0) = 501170
The population is decreasing since we are multiplying by .98 ^x
.98 is less than 1 so it is getting smaller each time.
1 -.98 = .02
It is decreasing by 2 % each year
2020-1995 =25 years
f(25) = 501170(0.98)^25
=302438.41862
Rounding to the nearest whole number
302438
To solve for the value of x, you can simply add all of the values and expressions together and make it equal to 180 degrees, since the sum of all angles in a triangle add up to this amount.
Then we can solve for X, by algebra.
