The unit price of a 128 ounce jug of milk is 4.8 cents per ounce. a 64 ounce cartoon of milk has a unit price of 5.1 cents per ounce. approximately how much money is saved by purchasing a larger jug instead of two cartons

You save the amount of  of money by buying a larger jug instead of two cartons

Step-by-step explanation:  

we know that

The total cost of a larger jug is

The total cost of two cartons of jug is

The difference is equal to

You save the amount of  of money by buying a larger jug instead of two cartons

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the answer to this is a. a^2 + b^2 = c^2
