Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50. if the sales tax rate is 8.25%, what will be the amount of sales tax on cassie's purchase?

 The required amount of sales tax is $2.97.

Step-by-step explanation:  Given that Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50 and the sales tax rate is 8.25%.

We are to find the amount of sales tax on Cassie's purchase.

The total amount of purchase is given by

Therefore, the amount of sales tax is given by

Thus, the required amount of sales tax is $2.97.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
