SI = PRT /100

1. SI = 400*5*1/100
        = 2000/100
        = $ 20

2. SI = 1000*8.5*3/100
        = 25.5*1000/100
        = $ 255

3.  SI = 200*9*1/2*100
         = 900/100
         = $9

4.  SI = 20000*12*3/100
         = 200*12*3
         = 7200

5.  SI = 1200*4.5*6/12*100
         = 4.5*6
         = $27
  
Amount to pay = Principal + SI
                        = 1200+27
                        = $1227 ( But this answer isn't there in the options )

If cscx=3, 90 degrees
ludmilkaskok [199]
We are given with 90<x<180 degrees and asks for the value of sin(x/2), cos(x/2) and tan(x/2). We just substitute the maximum and minimum angle to the equations. sin (180/2) is equal to 1 and sin (90/2) is equal to \frac{ \sqrt{2} }{2} to 1. cos (x/2) is equal to 0≤y≤<span>\frac{ \sqrt{2} }{2}. tan (x/2) is equal to 1 to infinity. </span>

Leni [432]

Answer:

CI=P*(1 + R/100)^18

A=(CI + P) = P(1+R/100)^18

13500/P=1(100+R/100)^18

A/P=(100+R/100)^18

A/P=(100+R/100)^18

A=13500$        as (750 * 18)

(13500)/P=(1 +1.15/100)18

(13500)/P=(1+1.15/100)18

13500=((1.0115)^18

P=R$10989.02

Step-by-step explanation:

CI=Compound Interest

A=Amount

P=Principal.
