Which will hold more cake batter the rectangular pan or two round pans

I don't know the size of the pans, but I'd probably say the rectangle ones.  

Step-by-step explanation:

Y'know, you have to calculate volume and all that put based on the info given rectangular pans usually hold more...although there are two round pans...please add some numbers to clarify!

False, since if there are two perpendicular lines with gradients m1 and m2, then m1*m2 = -1.

Taking this example -5/2 multiplied by 5/2 is equal to -25/4, which is not equal to -1.

To find the actual gradient of the perpendicular line you would have to divide -1 by -5/2, which gives you 2/5.
