I believe it is C. Multiply 640 by 7.5. You should get 4800
Answer:
$14
Step-by-step explanation:
given
Sharif : Jose ---> 2:7
this means that:
Fraction of total that Sharif gets = 2 / (2+7) = 2/9
Fraction of total that Jose gets = 7 / (2+7) = 7/9
we are given that Jose gets $49, hence
jose's fraction = 7/9 , represents $49
i.e
7/9 -----> $49
1/9 -----> $49 ÷ 7 = $7
Sharif's fraction = 2/9 -----> $7 x 2 = $14

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.
