10. The Coast Guard has sent a rescue helicopter to retrieve
passengers off a disabled ship. The ship has called in its
position as 1.7 miles from shore. When the helicopter
passes over a buoy that is known to be 1.3 miles from
shore, the angle formed by the shore, the helicopter,
and the disabled ship is 90°. Determine what
the altimeter would read to the nearest foot
when the helicopter is directly above the buoy.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

1/800 is the right answer

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
