Answer: A) $120,953 
Step-by-step explanation:
The formula to calculate the compound amount (semi-annually):-
 , where P is principal amount , r is rate of interest and n is the number of time periods.
, where P is principal amount , r is rate of interest and n is the number of time periods.
Given : Principal amount : P= $90,000
Rate of interest : 6% per annum = 0.06 per annum
Time period : n= 5 years

Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.
 
        
             
        
        
        
Answer: Mason made $185.00 
Step-by-step explanation:
For the first 10 suits he made $12.50 each suit, then he made $20 for the additional 3.  (Just ignore the "suits part ._.)
250*.05=12.50
250*.08=20
12.50*10=125
3*20=60
125+60=185.

Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
 ...(1)
 ...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).

Hence, the rotational speed is 0.38 rotation per second.
