Answer:
- $17,500 at 14%
- $16,000 at 12%
Step-by-step explanation:
Let x represent the amount loaned at 14%. Then the total interest earned is ...
0.14x +0.12(33,500 -x) = 4,370
0.02x = 350 . . . . . . . . . . subtract 4020 and simplify
x = 17500 . . . . . . . . . divide by 0.02
The amount loaned at 12% is $33,500 -17,500 = $16,000.
$17,500 was loaned at 14%
$16,000 was loaned at 12%
Helps you learn mathematical concepts, such as the four basic arithmetical operations and finding divisors.
Answer: Length = 12cm , width = 21cm
Step-by-step explanation:
Let the length be x , then the width is x + 9, That is
Length = x
Width = x + 9
The formula for calculating the perimeter of a rectangle is given by:
Perimeter = 2 ( Length + Width )
substituting the values , we have :
66 = 2 ( x + x + 9 )
66 = 2 ( 2x + 9 )
divide through by 2
66/2 = 2x + 9
33 = 2x + 9
subtract 9 from both sides
33 - 9 = 2x
24 = 2x
divide through by 2
therefore :
x = 12
This means that
Length = 12cm
Width = 12 + 9 = 21 cm
