Answer:

It would earn $ 185.87 ( approx )

Step-by-step explanation:

Since, the simple interest formula is,

I=\frac{P\times r\times t}{100}

Where,

P = principal amount,

r = rate per period,

t = number of periods,

Here,

P = $ 2,560,

r = 5\frac{1}{8}\%=\frac{41}{8}\%

t = \frac{17}{12}  years,   ( ∵ 1 year = 12 months )

Hence, the simple interest would be,

I=\frac{2560\times \frac{41}{8}\times \frac{17}{12}}{100}

=\frac{1784320}{9600}

\approx \$185.87

<u>Answer</u>

$185.86667


<u>Explanation</u>

The formula for simple interest is:

I = PRT

Where I ⇒ interest

           P ⇒ amount deposited.

          R ⇒ interest rate

          T ⇒ period for investing

17 months = 17/12 years

5 1/8 = 5.125

∴ I = 2,560 ×17/12 × 5.125/100

     = 2560 × 17/12 × 0.05125

      = $185.86667

To the nearest tenth answer = $185.90

Answer:

\rm x=\frac{46}{3}

\rm y=-\frac{25}{24}

Step-by-step explanation:

\huge\begin{array} {|c|} \hline\left. \begin{cases} {   \rm\frac{ 1  }{ 4  }  x+ \frac{ 4  }{ 5  }  y =  3  } \\ {   \rm\frac{ 5  }{ 16  }  x- \frac{ 1  }{ 5  }  y=5  }  \end{cases} \right. \\  \hline \end{array}

\\ \Large \overline{ \rm -   \: Steps \:  using  \: substitution \: - }

\rm \frac{1}{4}x+\frac{4}{5}y=3

\rm \frac{1}{4}x=-\frac{4}{5}y+3

\rm x=4\left(-\frac{4}{5}y+3\right)

\rm x=-\frac{16}{5}y+12

┈

\rm \frac{5}{16}\left(-\frac{16}{5}y+12\right)-\frac{1}{5}y=5

\rm -y+\frac{15}{4}-\frac{1}{5}y=5

\rm -\frac{6}{5}y+\frac{15}{4}=5

\rm -\frac{6}{5}y=\frac{5}{4}

\bold{ y=-\frac{25}{24}}

┈

\rm x=-\frac{16}{5}\left(-\frac{25}{24}\right)+12

\rm x=\frac{10}{3}+12

\bold{ x=\frac{46}{3}}

Find the slope of the line that passes through the points (3, 6) and (5, 3).
Temka [501]
(3,6)    (5,3)
(x1,y1)(x2,y2)

The slope equation is: y2-y1
                                 ---------
                                  x2-x1

Replace with numbers: 3-6/5-3

Minus 3 and 6 is equal to -3

Minus 5-3 is 2 

So the fraction is -3/2 (no need to divide because you can't simplify it)

So the slope is -3/2

For the equation you have to replace the letters by 0's 

3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides 
   0-2y=6
  -0      -0

-2y=6

Divide -2y from the 6

-2y=6
----  ---
  -2   -2

y=3 

The y intercept is 3 with the slope of -3/2
