1 gallon = 128 ounces
Divide total ounces by ounces per cup:
128 / 4 = 32
She had 32 servings
Equilateral: all sides are the same length
isosceles: two sides are the same length
obtuse: there is 1 obtuse angle
The mass of an object will never change no matter what, however, the weight relies on gravity. So therefore, the answer would be D.
Use the formula (new price-old price) / old price
32-40=-8
-8/40=-20%
the percent difference is 20%
the negative means it was a markdown
F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
