Answer:
n = 5/22
Step-by-step explanation:
That's a final solution.
Given that Kyle has received 900$ in cash as a gift and Kyle wants to invest that money in CD with 4% compound interest which is being compounded annually.
That means interest rate = 4% =
in decimals.
Since interest is compounded annually, we have to use compound interest formula.
That is amount after time t is 
Where P- initial amount = 900
r= rate of interest in decimals = 0.04
n= number of times interest is compounded per year = 1
t= number of years the money is invested = 5
Hence A = 
= $1094.9876
So, at the end of five year period, Kyle will have 1094.9876$ to put down in his car.

Answer: 28.8°
<u>Step-by-step explanation:</u>
∠A = 5(∠B) + 7.2°
∠B = ∠B
Since they are on a straight line, they form a linear pair (sum = 180°)
∠A + ∠B = 180°
Use Substitution:
5(∠B) + 7.2° + ∠B = 180°
Add like terms:
6(∠B) + 7.2° = 180°
Subtract 7.2° from both sides:
6(∠B) = 172.8°
Divide both sides by 6:
∠B = 28.8°
