What price should a retailer place on an item that costs him $6.95, if he wants a markup of 33%? $

zubka84 [21]

So he wants to mark the product up by 33%, now, if we take 6.95 to be the 100%, what is 33% of that?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6.95&100\\
x&33
\end{array}\implies \cfrac{6.95}{x}=\cfrac{100}{33}\implies \cfrac{6.95\cdot 33}{100}=x$

so the marked up price will be 6.95 + x.

A line segment has the endpoints (9, -16) and L (7,12) find the coordinates of its midpoints M

Anastasy [175]

Answer:

The answer to your question is: (8, -2)

Step-by-step explanation:

Data

A (9, -16)

L (7, 12)

Formula

$Xm = \frac{x1 + x2 }{2} Ym = \frac{y1 + y2}{2}$

Xm = $Xm = \frac{9 + 7}{2} Ym = \frac{-16 + 12}{2}$

Xm = 8 Ym = -2

Find b, given that a = 20, angle A = 30°, and angle B = 45° in triangle ABC

Kamila [148]

<span>The side b is opposite to the angle B, applying the law of the sines, we have:

</span> $\frac{a}{sinA} = \frac{b}{sinB}$
$\frac{20}{sin30^0} = \frac{b}{sin45^0}$
$\frac{20}{ \frac{1}{2} } = \frac{b}{ \frac{ \sqrt{2} }{2} }$
$20* \frac{ \sqrt{2} }{2} = b* \frac{1}{2}$
$\frac{20 \sqrt{2} }{2} = \frac{b}{2}$
$2*b =2*20 \sqrt{2}$
$2b = 40 \sqrt{2}$
$b = \frac{40 \sqrt{2} }{2}$
$\boxed{b = 20 \sqrt{2} }$
