The car you want cost 25,750. If the sales tax rate is 6.5% the how much sales tax will be added? What is the total cost for the
lilavasa [31]

Answer:The total cost for the car including tax is $27423.75

Step-by-step explanation:

The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be

6.5/100 × 25750 = 0.065 × 25750 = 1673.75

The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes

25750 + 1673.75 = $27423.75

Graph the image of kite ABCD after a rotation 180° counterclockwise around the origin.
rewona [7]

Solution:

Given a kite ABCD on a graphhh, with the coordinates given below

\begin{gathered} A(-8,-6) \\ B(-7,-2) \\ C(-1,-6) \\ D(-7,-10) \end{gathered}

If the kite is rotated 180° counterclockwise around the origin,

The rule for a rotation 180° counterclockwise around the origin is

(x,y)\rightarrow(-x,-y)

The coordinates of the kite after the rotation of 180° counterclockwise around the origin will be

\begin{gathered} A(-8,-6)\rightarrow A^{\prime}(8,6) \\ B^{\prime}(-7,-2)\rightarrow B^{\prime}^(7,2) \\ C(-1,-6)\rightarrow C^{\prime}(1,6) \\ D(-7,-10)\rightarrow D^{\prime}(7,10) \end{gathered}

The graph is shown below
