How many 1 1/2 liter bottles of water does it take to fill a 16 liter jug? show work
1 answer:
Answer: 11 bottles approximately.
Step-by-step explanation:
The first step you can apply in order to solve this exercise, is to convert the mixed number to a decimal number. The procedure to this is:
1. Divide the numerator 1 by the denominator 2.
2. Add the quotient obtained to the whole number part.
Then, this is:
According to the information provided in the exercise, a jug of 16 liters must be filled using bottles of 1.5 liters of water.
So, let be "x" the amount of 1.5 liters bottles of water that takes the fill the jug of 16 liters.
To find the value of "x", you need to divide 16 liters by 1.5 liters. Then:

Answer:
The equation of the parabola is , whose real vertex is
, not
.
Step-by-step explanation:
A parabola is a second order polynomial. By Fundamental Theorem of Algebra we know that a second order polynomial can be formed when three distinct points are known. From statement we have the following information:
,
,
From definition of second order polynomial and the three points described above, we have the following system of linear equations:
(1)
(2)
(3)
The solution of this system is: ,
,
. Hence, the equation of the parabola is
. Lastly, we must check if
belongs to the function. If we know that
, then the value of
is:
does not belong to the function, the real point is
.
