Help me with this!!! Fake answers will get reported

Mathematics
1 answer:
zlopas [31]3 years ago
6 0

Answer:

Step-by-step explanation:

there is an obscure rule that looks like this

DB/AB = AB/CB

AB=40 for this problem

DB = x

CB = 20

then

X/40 = 40/20

X = 40(40/20)

X = 40(2)

X=80

I find that hard to believe too,   :D

but the rule says that's right

Help please with this question
bazaltina [42]

M      =     Maturity  Value   ======>   $5,989.50

P        =     Principal Loan  Amount  =====> $7,972.02

I          =     Annual  Interest Rate    =======>  10%  (or,    .10 ) ===> $1,982.52

N         =      Number of Years   ======>   3  years

M       =        P( 1      +      i )^n   ======>   Solved for Amount Borrowed:

Solution:  M   =     $5989.50(1     +    .10 )^3  ======>  M   =  $7,972.0245  ====> $7,972.02   Bill Abel Borrowed.



Equation:    M       =        P( 1      +      i )^n

Let's solve your equation step-by-step.

m        =         5989.5(1       +       0.1)3

Step 1: Simplify both sides of the equation.

Add the numbers:  1    +   0.1     =    1.1

m     =    1.1^3       =     $5989.50

1.1^3         =      1.331

m            =     1.331     *     5989.50

Multiply the Numbers:

5989.50  *    1.331       =      7972.0245

m        =        $7972.0245  ======>  $7,972.02

Answer:     =======>     m     =       $7972.0245  =====> $7,972.02  Would be the amount Bill Abel Borrowed.    

The Amount of Interest Bill Abel would have paid ======>  $1,982.52



Check:  Maturity Amount  +  Annual For total cost of 3 Years   =    Amount Borrowed

$5989.50    +     $1972.52

m        =        $7972.02



Hope that helps!!!!                                                 : )
