2.25h(60m/hr)(1/3)=45m
So Rick spends 45 minutes studying math per night.
Let the radius of the circle be r. Then the line from the external point through the center of the circle which extends to the far point on the circle has length 3r .By the tangent - secant theorem
t^2 = 3r * r = 3r^2 ( where t is the length of the tangent).
So t = √(3r^2) = √3r answer.
Ok well...
1200 times .25 is 300 so subtract 1200-300= 900 is the decreased number :)
Hope it helps! :)
the right answer is
x = 4 and x = –10
I just take the test and I got it right I hope yall get it right to
Pretty fast consider 115ft wasn't enough to avoid an accident..
