If a patient drank 1/2-pint of apple juice and received 1 L via IV, what is the total amount of
fluids, in mL, they took in?
The total volume of fluid that the patient takes in is:
V = 1284.13 mL
What is the total amount of fluids, in mL, they took in?
We need to add the total volume of liquid that the patient consumes.
First, we need to rewrite both volumes in mL, remember that:
1 pint = 568.26 mL
Then for the 1/2-pint of apple juice:
1/2 pint = (1/2)*568.26 mL = 284.13 mL
And:
1L = 1000L
For the liter we have:
1 L = 1000ml
Then the total volume of fluid that the patient takes in is:
V = 284.13 mL + 1000ml = 1284.13 mL

solve for x - please help.
Answer:
x =20°
Step-by-step explanation:
since both sides are equal
3x° = (5x-40°)
3x = 5x - 40°
CLT( collect like terms)
40°= 5x - 3x
40° = 2x
40°/2= 2x/2
20° = x
therefore x =20°
When solving the quadratic equation x^2-10x+9=0
by completing the square, which of the following equations is a step in the process ?
The quadratic equation x² - 10x + 9 = 0. = 0 by completing the square, which of the following equations is a step in the process
(x – 10)2 = 34
(x – 10)2 = 16
(x – 5)2 = 34
(x – 5)2 = 16
The equation that is come in the process of solving the quadratic equation by completing the square is (x - 5)² = 16.Given that
The quadratic equation x² - 10x + 9 = 0.To find
The equation that come in the process of solving this quadratic equation by completing square method.So, according to the question
We have
x² - 10x + 9 = 0.We have to solve that quadratic equation by completing square method.
So, we know that
In Completing square method, we have to convert this quadratic equation in square form.
So,
x² - 10x + 9 = 0.
Now, by multiplying both sides by the square of the x-coefficient, we get
x² - 10x + 9 + (-10/2)² = 0 + (-10/2)²
x² - 10x + 9 + (-5)² = 0 + (-5)²
Now, simplify it
x² - 10x + 9 + (-5)² = 0 + (-5)²
x² - 10x + 9 + 5² = 0 + 5²
x² - 2×5×x + 5² + 9 = 0 + 5²
∵ (a - b)² = a² - 2ab + b²
∴ (x - 5)² = x² - 10x + 5²
(x - 5)² + 9 = 25 [since (x² - 10x + 5² = (x - 5)²]
(x - 5)² = 25 - 9
(x - 5)² = 16

A rental car company charges prices based on the number of days
you rent the car. If you only rent it for up to 4 days, it will cost a flat
fee of $50 plus $25 per day rented. If you rent it for more than 4
days, they only charge you a flat fee of $45 and $20 per day rented.
How much will you owe if you rent the car for 7 days?
Using linear equations, A rental car company charges prices based on the number of days you rent the car will charge $185 if you rent the car for 7 days.
What is a linear equation?A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
Let us consider the number of days = x
The equation when number of days(x) <= 4,
⇒ $50 + $25x1 = y1
If the car is rented for more than 4 days, (x>4)
⇒ $45 + $20x2 = y2
Now, we are to calculate the rent for 7 days,
which equals,
y2 = $45 + $20x2
for x2 = 7,
y2 = $45 + $20 × 7
⇒ 45 + 140
⇒ $185

The depth of the orange juice in the carton is 8 cm.
Jane closes the carton.
Then she turns the carton over so that it stands on the shaded face.
Work out the depth, in cm, of the orange juice now.
The new depth of the orange juice is now 4cm
Calculating VolumeFrom the question, we are to calculate the depth of the orange juice after Jane turns the carton
First, we will determine the volume of orange juice in the carton.
The volume of orange juice in the carton = 10 cm × 6 cm × 8cm
Volume of orange juice in the carton = 480 cm³
Now, we will determine the depth of the orange juice when the carton stands on the shaded face
If carton stands on the shaded face,
The length becomes 20 cm
and
The width becomes 6 cm
Let the new depth of the orange juice be h
Then,
We can write that
480 = 20 × 6 × h
480 = 120 × h
h = 480/120
h = 4 cm
Hence, the new depth of the orange juice is now 4cm

A minor league baseball team plays 94 games in a season. if the team won 16 more than twice as many games as they lost, how many wins and losses did the team have?
The number of wins is 68 ad losses is 26.
How to compute the value?Let the number of losses = l
Therefore, the number of wins will be: = (2 × l) + 16 = 2l + 16
Total games = 94
Therefore we will add the equation
l + 16 + 2l = 94
3l + 16 = 94
3l = 94 - 16
3l = 78
Divide
l = 78/3
l = 26
Losses = 26
Number if wins = 2l + 16 = 2(26) + 16 = 52 + 16 = 68

A)- The distribution is skewed left.
B)- The histogram has one mode, at 74 to 76 years.
What is histogram?The distribution of numerical data is roughly shown by a histogram. Karl Pearson is credited with coining the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count how many values fall into each interval. The bins are often defined as a series of discrete intervals that don't overlap. Histograms provide a general idea of the density of the underlying distribution of the data, and are frequently used for density estimation: estimating the probability density function of the underlying variable. The bins (intervals) must be adjacent and are frequently (but not always) of equal size.

The graph of an absolute value function has a vertex of (3, 6) and crosses the x-axis at (-3,0) and (9,0). What is the equation of the absolute value function?
The equation of the absolute value function is y = -|x - 3| + 6
How to determine the equation of the absolute value function?The given parameters are
Vertex = (3, 6)
Crosses the x-axis at (-3,0) and (9,0)
An absolute value equation is represented as
y = a|x - h| + k
Where
Vertex = (h, k)
So, we have
y = a|x - 3| + 6
At (-3, 0), we have
0 = a|-3 - 3| + 6
This gives
0 = a|-6| + 6
So, we have
0 = 6a + 6
Solve for a
a = -1
Substitute a = -1 in y = a|x - 3| + 6
y = -|x - 3| + 6

The value of the composite function (fog)(-11) is 3√14 - 41.
What is a composite function?When the output of one function is given to the input of another function they are called composite functions.
In (fog)x which is [f{g(x)}] here the out of the function g(x) is the input of the function f(x).
Given, Are two functions f(c) = 3c - 8 and g(c) = √14 - c.
Now, We know that (fog)(c) is the output of g(c) is in the input of f(c).
So, g(-11) = √14 - 11.
