What is the different properties of real number under addition?
The properties for real numbers are as follows:closure: for any numbers x and y, x + y is a real number.associativity: for any numbers x, y and z, x + (y + z) = (x + y) + z = x + y + zidentity: for any number x, there is a number, denoted by 0, such that x + 0 = x = 0 + xInvertibility: for any number x, there is a number denoted by -x such that x + (-x) = (-x) + x = 0Commutativity: for any numbers x and y, x + y = y + x.

How do you figure volume in square yards for a rectangle 30 feet by 50 feet at 4 inches thick?
Cubic yards. Volume is cubic.30 feet = 10 yards50 feet = 16.66 yards4 inches (1 foot/12 inches)(1 yard/3 feet) = 0.11 yards10 y * 16.66 y * 0.11 y= approximately 18 and 1/3 cubic yards============================
