Answer:
x = 5°
Step-by-step explanation:
5x + 21° + 20x + 34° = 180°
25x + 55° = 180°
25x = 180° - 55°
25x = 125°
x = 125°/25
x = 5°

Answer:14
Step-by-step explanation:
Using the formula for continuous compounding, F=Pe^rn, we will be able to determine the number of years it took P= 200 to become F= 350. We just substitute the given numbers into the equation, let F=350, P=200, and r=0.08. We will obtain n=7 years, which is the number of years for 200 to become 350.
This is just like working with money in a bank account
that's earning 12% interest.
If the population is 422,000 today, and
' n ' is the number of years after today,
then
Population = 422,000 (1.12)ⁿ .
