Subtracct second equation from the first
a - b = - 4995 a = -4995 + b
2009 ( -4995+b) + 2008 b = 2007
2008 b + 2009 b = 10036962
b = 2498.621
then a = -2496.379
Yes, there are diagonal squares (hence the total squares 55)
and I suppose these 2 x 2 and 3 x 3 squares ARE a different size
so SIX different sizes ya think ?
1st stage 2 players notified
2nd stage 4 more players notified total 6
3rd stage 8 more total 14
4th stage 16 more total 30
5th stage 32 more total > 50 5 stages needed
-b/2a will be the 'x' value a = 1 b = -19
use this value in the equation to calculate the 'y' value of the vertex .....
Volume of a cone = 1/3 pi r^2 h
= 1/3 pi (2.5)2 (10) note that 2.5 is the RADIUS
=~ 65.4 cm3 of ice cream
Hmmmm.... shouldn't that be ?
1 - (5/6)3 = 11/36
The question asks for the number of different sizes.....not the number of squares
2 x2
3x3
4x4
5x5
four different sizes
You're welcome !
6930 / 9 = 770 m/hr
6060/6 = 1010 m/hr
jet speed in still air is the average = 890 m/hr
wind speed is diff between this speed and one of the above speeds = 120 m/hr
Chris has strung a right triangle of lights with legs 48 and 55
the diagonal is fond with Pythag theorem
d = sqrt (48^2 + 55^2) = 73 ft
48 + 55 + 73 = 176 ft total
