Answer:
x = 8
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Sum the exterior angles and equate to 360
62 + 66 + 77 + 59 + 12x = 360, that is
264 + 12x = 360 ( subtract 264 from both sides )
12x = 96 ( divide both sides by 12 )
x = 8

Answer:
The population in 20 years will be 781.
Step-by-step explanation:
The population of the town can be modeled by the following equation:
In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate, as a decimal.
The initial population of 500 increases by 25% in 10 years.
This means that 
We use this to find r.
Applying ln to both sides
So
What will be the population in 20 years
This is P(20)
The population in 20 years will be 781.
Answer:
25 choices
Step-by-step explanation:
Given
Possible Combinations: 1 to 25
Selections: 3 numbers
Required
Determine the number of choices of the first number
The first number of the lock can be any of 1 to 25.
This is so because when you counting from 1 to 25, there are 25 numbers
<em>Hence, number of choices is 25 numbers</em>
