Onondaga Electronics operates on a net-profit rate of 20% on its printer cables. If the markup is $8.95 and the overhead is $4.3

asambeis [7]

Answer:

The selling price be $79.56 .

Step-by-step explanation:

Let us assume that the cost price be x.

As given

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

= x + 8.95 + 4.31

= x + 13.26

Profit = Selling price - Cost price

= x + 13.26 - x

= $ 13.26

Formula

$Profit\ percentage = \frac{Profit\times 100}{Cost\ price}$

Putting the values in the above formula

$20= \frac{13.26\times 100}{x}$

$x= \frac{13.26\times 100}{20}$

$x= \frac{1326}{20}$

x = $ 66.3

Thus cost price be $66.3 .

Thus

Selling price = $66.3 + $13.26

= $ 79.56

Therefore the selling price be $79.56 .

$\bf h=-15cos\left( \frac{2\pi }{5}t \right)\qquad \boxed{h=8}\qquad 8=-15cos\left( \frac{2\pi }{5}t \right)
\\\\\\
\cfrac{8}{-15}=cos\left( \frac{2\pi }{5}t \right)\implies cos^{-1}\left( \frac{8}{-15}\right)=cos^{-1}\left[ cos\left( \frac{2\pi }{5}t \right) \right]
\\\\\\
cos^{-1}\left( \frac{8}{-15}\right)=\cfrac{2\pi }{5}t\implies \cfrac{5}{2\pi }\cdot cos^{-1}\left( \frac{8}{-15}\right)=t\\\\

The equation of a line is given by, 13x – y + 12 = 0. Find the slope and both the intercepts.

MArishka [77]

Answer:

The slope is 13.

The x intercept is $x=\frac{-12}{13}$ .

The y intercept is $y=12$ .

Step-by-step explanation:

1. Finding the slope.

This is a linear equation, because it's graph forms a line. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, the slope is 13.

2. Finding the x intercept.

The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:

$13x-y + 12 = 0\\\\13x-(0) + 12 = 0\\\\13x+12 = 0\\\\13x= -12\\\\x=\frac{-12}{13}$

The x intercept is $x=\frac{-12}{13}$ .

3. Finding the y intercept.

The y intercept is found when the value of x is 0. Let's replace the value of x for 0 in the equation and solve the y:

$13x-y + 12 = 0\\\\13(0)-y + 12 = 0\\\\-y + 12 = 0\\\\-y=-12\\\\y=12$

The y intercept is $y=12$ .
