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

Jane has a carton of orange juice.
The carton is in the shape of a cuboid.
20cm-
6cm
10 cm
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

b. Find the change in temperature if the temperature rises from -18°F to 15°F.
The change in temperature is 33°F.
According to the question we have been given that there are two temperature readings which are, -18°F and 15°F.
We need to find the change in temperature that is we need to find the difference. And for that we will use distance formula.
The formula to find the distance between the two numbers p and q is
= |p-q|
Here , p = -18°F and q = 15°F
Putting the required values in the above formula we get
= |-18 - 15| °F
= |-33| °F
= 33°F

2 km, and the Mariana Trench is deeper
−2 km, and the Japan Trench is deeper
20 km, and the Japan Trench is deeper
−20 km, and the Mariana Trench is deeper
The difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper
What is the difference of depths between them, and which trench is deeper?
The given parameters are:
Mariana Trench = 11 km
Japan Trench = 9 km
The Mariana Trench is deeper because 11 is greater than 9
The difference between the depth is
Difference = 11 km - 9 km
Difference = 2 km
Hence, the difference of depths between them, and which trench is deeper is (a) 2 km, and the Mariana Trench is deeper

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

how do you write slope-intercept form of the equation of each line given the slope and y-intercept.
slope: -5/4
y-intercept: 4
Answer:
y = -5/4 x + 4
Step-by-step explanation:
Make sure the -5/4 is beside the x. It should not look like the x is on the bottom of -5/4 alongside of the 4.
Slope-intercept form of an equation is a shortcut, fill-in-the-blank form you can use to write the equation of a line.
Slope-intercept eq:
y = mx + b
You fill in slope where the m is. And you fill in the y-intercept for the b.
In your problem they gave you the slope: m = -5/4 and the y-intercept: b=4.
Fill the m and b in with the given numbers!
y = -5/4 x + 4
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

the accompanying histogram shows the life expectancies at birth for 190 countries as collected by an international health agency. a) describe the shape. b) how many modes does the histogram have?
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.
