Here is the answer We know that all the segments are equal. therefore each segment will be = 4^9 - 4^7 first = 4^7 second = 4^9 third = 4^9 + (4^9 - 4^7) fourth = 4^9 + (4^9 - 4^7) + (4^9 - 4^7) = 3(4^9) - 2(4^7) Hope this helps. AGREE...I've the same answer by the same calculation with "paral...

Re: Ice Cream

The outline of a sign for an ice-cream store is made by placing of the circumference of a circle with radius 2 feet on top of an isosceles triangle with height 5 feet, as shown above.

Okay, It might be late, but I don't understand how you are getting the 25/3 ?!? Isn't 250/30 giving you the amount of gasoline consumed? EDIT: NVM you removed the 0 from each number. But see I did 25/3=8.33/12=wich reduces to 2/3..how did you know to put muliple the 12*3 to get 25/36?? I understand...

From the question we can find:

Area of Metal Frame = (phi)r^2 - (phi) (r-s)^2

= (phi)r^2 - (phi) (r^2 - 2rs + s^2)
= (phi)r^2 - (phi)r^2 + 2(phi)rs - (phi)s^2
= 2(phi)rs - (phi)s^2
= (phi)s (2r - s)

Hence the answer is D (CMIIW ya)

Hope this helps...Enjoy your day

I am agree with Lordpapi63, we better use 100 employees to represent total employees for company X. But i want to describe different approach: We knew that 30% of the employees live over 10 miles from work.
