Answer:
23 degrees
Step-by-step explanation:
If <ADC is the arc measure of the circle, by definition the center angle (<ABC) has the same measure as its intercepted arc.
No, they are not equivalent.
5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.
(using distribution property)
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.
78% = 78 / 100 = 0.78
What is 78% of 380
= 78% * 380
= 0.78 * 380
= 296.4
U said I should round it up IF NECESSARY so yeah....
