Answer:
- $2.79 per bottle
- $0.186 per ounce
Step-by-step explanation:
When you talk about "unit price," you need to define the unit of interest. Unit prices on grocery store shelves don't always use the same unit, even for like items. Here it might be convenient to use any of the following as the "unit":
- 1 bottle
- 1 ounce
- 1 pint (16 ounces)
- 1 cup (8 ounces)
The "unit price" is computed as ...
unit price = (price for some number of units)/(the number of units)
The "number of units" may be larger, smaller, or equal to 1.
Then the price per cup (8 ounces) would be ...
unit price = (price for 15 oz)/(15/8 cups) = ($2.79)(8/15)
= $1.488 per cup
__
The price per ounce would be ...
unit price = ($2.79)/(15 oz) = $0.186/oz
__
We assume that the unit of interest is probably 1 ounce, but it could be something else. Your grader may expect the value to be rounded to the nearest cent, $0.19 per ounce.

Answer:
see explanation
Step-by-step explanation:
Check the value of the discriminant
Δ = b² - 4ac
• If b² - 4ac > 0 then roots are real
• If b² - 4ac = 0 roots are real and equal
• If b² - 4ac < 0 then roots are not real
given (x - a)(x - b) = k² ( expand factors )
x² - bx - ax - k² = 0 ( in standard form )
x² + x(- a - b) - k² = 0
with a = 1, b = (- a - b), c = -k²
b² - 4ac = (- a - b)² + 4k²
For a, b, k ∈ R then (- a - b)² ≥ 0 and 4k² ≥ 0
Hence roots of the equation are always real for a, b, k ∈ R
So Angle GEN and FED are vertical angles, which means that their angles are congruent. Therefore, Angle FED is 60°
Angle GEN and DEN are a linear pair, which means that they are supplementary angles (add up to 180). To find Angle DEN, we have to form the equation: 60 + DEN = 180
For this, all you have to do is subtract 60 on both sides, and your answer will be: DEN = 120°
