Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR =  x 100%
 x 100%
where:
RR is the rate of return
 is the final amount = $690 -  $6 = $684
 is the final amount = $690 -  $6 = $684
 is the initial amount = $15 x 40 = $ 600
 is the initial amount = $15 x 40 = $ 600
So that,
RR =  x 100%
 x 100%
      = 0.14 x 100%
      = 14%
Therefore, the rate of return is 14%.
 
        
             
        
        
        
Answer:
a=90° (given)
b=180°-90°-59° (angles on a straight line)
c=180°-59° (angles on a straight line)
d=59° (vertically opposite angles)
Step-by-step explanation:
I said the answer already 
 
        
             
        
        
        
The rate of the wind is given to be 210 the rate of the plane in mid air is given as 830
<h3>Howe to solve for the rate of the plane and wind</h3>
In 7 hours the kilometer traveled =  4340
P + W = 4340/7 
= 620
P-W = 3120/3 hours
= 1040
2p = 1040 + 620
= 1660
p =830
W = 1040 - 830
= 210
Hence the rate of the wind is given to be 210 the rate of the plane in mid air is given as 830

To find the original price before the increase, divide the new price by 1 + the percent of increase.
198 / 1.20 = 165
The original price was $165
