natta225 [31]

Answer:

$ 158.95

Step-by-step explanation:

Reduction = 25% of 199

                = 0.25 * 199

                = $ 49.75

Price of the tablet after reduction = 199 - 49.75 = $ 149.25

Sales tax = 6.5% of 149.25

              = 0.065 * 149.25

              = $ 9.70

Total price that he need to pay = 149.25 + 9.70

                                                      = $ 158.95

irga5000 [103]

We have been given that Jin cut a round gelatin dessert into 8 equal pieces. Seven of the pieces were eaten. We are asked to find the angle measure of the dessert that was left.

We know that there are 360 degrees degrees in a circle all the way around the center.

Since Jin cut all pieces of same size, so angle measure of all pieces will be equal.

To find the angle measure of each piece, we will divide 360 by 8.

\text{Angle measure of each piece of dessert}=\frac{360^{\circ}}{8}

\text{Angle measure of each piece of dessert}=45^{\circ}

Therefore, the angle measure of the dessert left dessert piece is 45 degrees and option D is the correct choice.
