9.) A new basketball is $10.95 and is 20% off. The sales tax is 7%.
blagie [28]

If you are trying to find the cost of the basket ball, it is $8.15.

Step 1: Find 20% of 10.95- which is 2.19- and subtract 2.19 from 10.95-which is 8.76.

Step 2: Find 7% of 8.76-which is 0.6132- and subtract 0.6132 from 8.76-which is 8.1468

Step 3: Round to the nearest hundredth, which gives you 8.15.

Thus, $8.15 is your answer.

GEOMETRY HELP URGENT?
nadezda [96]

Let the centre be O and the line with one end point at the centre and another at the chord CD touches the chord at S .

So CS is the half of 36.7 = 18.35

sin \angle COS = \frac{18.75}{21.8}

\angle COS = sin^{-1}(\frac{18.75}{21.8}) =59.35 degree\\

Therefore,


\angle COD =2*59.35 =118.7

Therefore the measurement of arc CD is 118.7 degree.
