Answer:
Hans deposits $6000 into an account.
=> Principal P = 6000
Simple interest rate 5% per year.
=> Rate R = 5% = 5/100 = 0.05
The formula to calculate the amount of interest after 4 years:
A = P x R x years = 6000 x (5/100) x 4 = 1200$
Hope this helps!

Answer:
<u>Geometric Progression</u> is the explicit rule for the given sequence: 11, 22, 44, 88...
First term (a) = <u>11</u>
Common ratio (r) = 22/11 = 44/22 = 88/44 = <u>2</u>
Formula used in Geometric Progression is :---

Answer:
Anna is 43 years old and Jacob is 41 years old
Step-by-step explanation:
x + 1 + x + 3 = 92
2x + 4 = 92
