Answer:

6/7

Step-by-step explanation:

Product of slope of perpendicular line = -1

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\

          = \frac{7-0}{3-9}\\\\=\frac{7}{-6}\\\\=\frac{-7}{6}

Slope of the  perpendicular line = -1/m = -1 ÷ \frac{-7}{6}

                                                     = -1 * \frac{-6}{7} = \frac{6}{7}

The camera cost $540 if the sales tax is 7.2% what is the tax change and the total cost?
soldier1979 [14.2K]

Answer:

38.88

Step-by-step explanation:

Convert the problem to an equation using the percentage formula: P% * X = Y.

P is 10%, X is 150, so the equation is 10% * 150 = Y.

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
