B, 190.
First you find the area of the circle (pi times radius squared) however, since you are given diameter, you must find radius by dividing diameter by 2. So, your radius is 9, then you plug it into the formula and you get 254.5. After multiplying this by 0.75 because you only want to find 75 percent of the area, you get the answer of 191m
Let p and w represent the speed of the plane and the speed of the wind, respectively.
.. speed = distance/time
.. p +w = 720/3 = 240
.. p -w = 720/4 = 180
Add the two equations to eliminate w.
.. 2p = 420
.. p = 210
.. w = p -180 = 30
The speed of the wind is 30 mph.
The speed of the plane in still air is 210 mph.

<h3><u /></h3><h3><u>Percentages</u></h3>
Given that Jamie and Emily are married and make a total annual gross pay of $91,500, to determine their total income tax at 12% rate, the following calculation must be performed:
- 91500 x 12/100 = X
- 91500 x 0.12 = X
- 10980 = X
Therefore, their total income tax is $10,980.
