Sandy borrowed 6709 R.O from a bank to buy a piece of land. If the bank charges 12 1/3 % compounded each two months, what amount

enot [183]

Answer:

she is paying back 9112.5 R.O

Interest paid back is 2,403.95

Step-by-step explanation:

To find the amount, we use the compound interest formula.

This is given as;

A = I( 1 + r/n)^nt

where A is the amount we are trying to calculate

I is money borrowed = 6709

r is the interest rate = 12 1/3% = 37/3 = 12.33% which is same as 12.33/100 = 0.1233

n is the number of times interest is compounded. We have 15 2 months in 2 and a half years

t is the number of years = 2.5

Plugging these values, we have;

A = 6709(1 + 0.1233/15)^(15)(2.5)

A = 6709(1.0082)^(37.5)

A = 9112.95 R.O

Interest is amount - principal( money borrowed)

9112.95 - 6709 = 2403.95

Find a common difference of the arithmetic sequence -2, -1 4/5, -1 3/5, -1 2/5,

elixir [45]

Answer:

The common difference is $\frac{1}{5}$ or 0.2

Step-by-step explanation:

Given:

Arithmetic Sequence -2, -1 4/5, -1 3/5, -1 2/5,

First term = a₁ = -2

Second term = a₂ = $\frac{-9}{5}$

Third term = a₃ = $\frac{-8}{5}$

Fourth term = a₄ = $\frac{-7}{5}$

To Find:

Common Difference = d = ?

Solution:

Formula for Common Difference d , $\textrm{common difference}= \textrm{Second Term} -\textrm{First Term}=\textrm{Third Term}-\textrm{Second Term}$

$\textrm{common difference} = a_{2}- a_{1}= a_{3}- a_{2}=a_{4}- a_{3}$

∴ $d = \frac{-9}{5}-(-2)\\d=\frac{-9}{5}+2\\d=\frac{1}{5}\\ \therefore d =0.2\\$

The common difference is $\frac{1}{5}$ or 0.2

Please help me anyone I need help with this question

Leto [7]

Answer:

(d) 2x +y = 8

Step-by-step explanation:

The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:

2x +y = 5 . . . . . . given equation in standard form

The other equation in a system with no solution will look like this, but will have a different constant:

2x +y = 8 . . . . . . does not intersect the given equation

_____

<em>Additional comment</em>

All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:

a: 2x -(-2x+5) = 8 ⇒ 6x -5 = 8 . . . one solution: x=13/6

b: x +2(-2x+5) = 8 ⇒ -3x +10 = 8 . . . one solution: x=2/3

c: x -2(-2x+5) = 8 ⇒ 5x -10 = 8 . . . one solution: x=18/5

d: 2x +(-2x+5) = 8 ⇒ 5 = 8 . . . no solution
