My calculator gave me the wrong answer The sales tax in your city is 4.4% and an item costs $3 before tax
How much tax would you pay on that item?
Round to the nearest hundredth or cent.

Icould really use some with this question.

Solve these problems: 1.what is the perimeter of an equilateral triangle with sides measuring 6cm? 2. a regular pentagon has sides measuring 3.2 cm. what is its perimeter? 3. a regular decagon has sides of 3.5mm . what is it’s perimeter? 4. a regular octagon has a perimeter of 64cm. what is the length of one of the sides? 5. a regular hexagon has a perimeter of 72mm . what is the length of one of the sides? 6. what is the perimeter of a rhombus with sides measuring 11m?

Change negative exponents to positive. then solve. round to four decimal places
