Answer:

She would pay $2.80 in sales tax.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Megan paid $2.52 in sales tax on an item that cost $36.00 before tax. How much in taxes for $40.00 before taxes?

$2.52 - $36.00

x - $40.00

Applying cross multiplication

36x = 40*2.52

x = \frac{40*2.52}{36}

x = 2.8

She would pay $2.80 in sales tax.

(7,9) has a slope of 1. Write equation in slope intercept form
Nadya [2.5K]

Step-by-step explanation:

<em>Here, slope of the line (m) = 1</em>

<em>Here, slope of the line (m) = 1And, the line passes through the point (7,9)</em>

<em>Equation </em><em>of </em><em>the </em><em>line </em><em>is </em><em>given </em><em>by </em>

<em>y </em><em>-</em><em> </em><em>y1</em><em> </em><em>=</em><em> </em><em>m </em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>x</em><em>1</em><em> </em><em>)</em>

<em>y </em><em>-</em><em> </em><em>9</em><em> </em><em>=</em><em> </em><em>1</em><em>(</em><em> </em><em>x </em><em>-</em><em> </em><em>7</em><em>)</em>

<em>y </em><em>-</em><em> </em><em>9</em><em> </em><em>=</em><em> </em><em>x </em><em>-</em><em>7</em>

<em>x </em><em>-</em><em>7</em><em>+</em><em>9</em><em>-</em><em>y</em><em> </em><em>=</em><em> </em><em>0</em>

<em>x </em><em>-</em><em> </em><em>y </em><em>+</em><em> </em><em>2</em><em> </em><em>=</em><em> </em><em>0</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>is </em><em>the </em><em>required </em><em>equation </em><em>of </em><em>the </em><em>line. </em>

Polygon PQRS, shown in the figure, is dilated by a scale factor of 0.5 with the origin as the center of dilation, resulting in p
nata0808 [166]

Based on the above:

The slope of P'Q'  is = -3/2

The length of  P'Q' is approximately = \sqrt[3]{13}

<h3>What is the polygon about?</h3>

The slope of P'Q'

=  -6/4 = -3/2

The length of  P'Q' =

 P'Q' = \sqrt{6^2 + 4^2}

= \sqrt{52}

= \sqrt[2]{13}

Therefore;

P'Q' = \frac{3}{2}

 P'Q' =    \frac{3}{2}  x \sqrt[2]{13}

= \sqrt[3]{13}
