1. $5.76/64 Ounces
2. $1.80/15 Ounces
1. $0.09/ounce
2. $0.12/ounce
So, in conclusion, the 64 ounce bottle is cheaper than the 15 ounce bottle by $0.03.
Answer:
Below.
Step-by-step explanation:
a. Φ^2 − Φ − 1 = 0
Φ2 − Φ = 1
(Φ - 0.5)^2 - 0.25 = 1
(Φ - 0.5)^2 = 1.25
Φ - 0.5 = √(1.25) (We only take the positive root).
Φ = 0.5 + √(1.25)
b. I used Completing the square.
c. Φ is irrational That is it cannot be represented as a fraction a/b and because of this it can only be approximated by a decimal.
A line is 180 degrees so write x+(4x-20)=180
