Answer:
The number of cds to be sold to hit a weekly revenue of 1000 pesos is 25
Step-by-step explanation:
Here, we have the revenue function and we want to know the number of cds to be sold to hit a particular revenue value.
Mathematically from the question;
r = 2x^2 - 10x
in the question; r = 1000
so ;
2x^2 - 10x = 1000
divide through by 2
x^2 -5x = 500
so;
x^2 -5x -500 = 0
x^2 -25x + 20x -500 = 0
x (x -25) + 20(x -25) = 0
(x -25)(x + 20) = 0
x -25 = 0 or x + 20 = 0
x = -20 or 25
Since the number of cds cannot be negative, we only select x = 25 as the correct answer
Answer:
30lbs of recyclables.
Step-by-step explanation:
-Let x be the corresponding lbs of recyclables to 40lbs of trash.
-Given that for every 100lb of trash, 75lb is recyclable.

Hence, thee are 30lbs of recyclables in 40lbs of trash.
5/8 are eaten
So if you do 8/8 - 5/8 you get 3/8
1 yard = 36 inches
4 yards = 144 inches
Each piece is (144/5) inches long = 28.8 inches
