Answer:
a. 64, 128, 256 (geometric)
b. 11, 13, 15 (arithmetic)
c. 53, 61, 69 (arithmetic)
Step-by-step explanation:
(a) Each term is twice the previous term. so it is geometric with a common ratio of 2
(b) The difference between each term is 2. So it is arithmetic with a common difference of 2
(c) The difference between each term is 8. So it is arithmetic with a common difference of 8
Given:
Principal = $1400
Simple rate of interest = 1.25%
Time = 6 month
To find:
The balance of the account after simple interest.
Solution:
The formula for simple interest is

Where, P is principal, r is the rate of interest in % and t is time in years.
Time = 6 months
=
year
= 0.5 year
Putting 1400, r=1.25, t=0.5 years.



Now, the amount is



Therefore, the balance of the account after the simple interest is $1408.75.
Answer:
180 meters
Step-by-step explanation:
You first need to find the length of each line:
PQ= 75 meters
PR= 60 meters
RQ= 45 meters
You then add all of the sides together.
75 + 60 + 45 = 180
