Answer:
B
Step-by-step explanation:
x² - 12x + 11 = 0 ( subtract 11 from both sides )
x² - 12x = - 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 6)x + 36 = - 11 + 36
(x - 6)² = 25 ( take square root of both sides )
x - 6 = ± = ± 5 ( add 6 to both sides )
x = 6 ± 5
Then
x = 6 - 5 = 1 ⇒ (1, 0 )
x = 6 + 5 = 11 ⇒ (11, 0 )
Solution: The total cost of the gift including the tax = $55.80
The amount paid by Montel = $14
The amount paid by Raymond is
Therefore, Raymond paid $18.6
The amount paid by Emily is
25% of 55.80
Therefore, Emily paid $13.95
We also know that the remaining amount is paid by Leanne.
Therefore, the remaining amount is:
Total amount - Amount paid by Montel, Raymond and Emily
The amount paid by Leanne is $9.25
We clearly see, Raymond has paid $18.6, which is the greatest part of the cost $55.80
The volume of each container is: 25,133
Given:
height of container (h) = 80 cm
diameter of container (d) = 20 cm
radius = half of diameter = of
Recall:
Volume of a cylinder =
<em>Substitute the values into the formula:</em>
Therefore, volume of each cylinder is approximately 25,133
