20% chance of drawing out of 52 because it is probly shuffeld
To solve the problem we must establish two equations.
let x be the mass of the 20 cents almonds
y be the mass of the 36 cents mixture
first equation is:
x + 40 = y
the second equation is:
0.2x + 40(0.4) = 0.36y
solving the equations simultaneously
x = 10 lb of the 20 cents almonds is needed to mix
Answer:
b(x) = -2x² + 7x + 114
Step-by-step explanation:
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity
The required equation is given by,
Given that:
Perimeter=194 cm
Width=w
Length, L= 4w-3
Formula for perimeter of rectangle:
P=2(L+W)
Put values
194=2(4w-3+w)
194=2(5w-3)
Divide both sides by 2.
97=5w-3
Add 3 to both sides
100=5w
w=20
So length= 4 (20) -3 = 80-3 =77 cm
and width= 20 cm
Answer: Length=77 cm and width=20 cm
