Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%
Answer:
Step-by-step explanation:
3. x^2 +3x=54
x^2 +3x -54 = 0
(x-9)(x+6) = 0
x = 9 and x = -6
4. X^2 - 10x + 21 [(x - 7)(x - 3)
Answer:
The original nimber is 67.
Step-by-step explanation:
Let the two digits be x and y.
According to the question.
The sum of two digits of a two digit number is
x + y = 13
or, x = 13 - y
And, a two digit number can be written as
x × 10 + y
when the digits are reversed, the number can be written as
y × 10 + x
the original number increases by 9. i.e.
y x 10 + x = x × 10 + y + 9
Replacing value of x by 13 - y,
y × 10 + 13 - y = 10(13 - y) + y + 9
10y + 13 - y = 130 - 10y + y + 9
9y + 13 = 139 - 9y
18y = 139 - 13
18y = 126
y = 126/18
y = 7
So, x = 13 - y
= 13 - 7
= 6
The original number is x × 10 + y = 6 x 10 + 7 = 67.
