Answer: k=G/ 3 pi
Step-by-step explanation:just make k the subject of the formulae by dividing through by 3 pi
 
        
             
        
        
        
Answer:
#a. $80
#b. $1680
Step-by-step explanation:
We are given;
- Amount invested (principal) is $1600
 - Rate of interest is 5%
 - Time = 1 year 
 
We are required to determine the amount of simple interest earned and the amount or balance in the account after 1 year.
#a. Interest earned 
To calculate simple interest we use the formula;
I = (PRT) ÷ 100
Where, P is the principal, R is the rate, T is the time and I is the simple interest.
Therefore;
I = (1600 × 5 × 1) ÷ 100
  = $80
Therefore, simple interest earned is $80
#b. Balance of the account (Amount accrued)
We are going to use the formula;
A = P + I , where A is the amount accrued, P is the principal and I is the simple interest earned.
Therefore;
Account balance = $1600 + $80
                             = $1680
Thus, the account balance after 1 year will be $1680
 
        
             
        
        
        
I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
