To question 16, we see that for every change of plus 2 drinks, they pay an additional value of $2.50. It means that each drink does cost half of this value.
This way, the equation that will give the value of the total cost will be:
[tex]Y=1.25\times X[/tex]Where X stands for the number of drinks, and 1.25 is the value of a single drink.
From the solution presented above, we are able to conclude that the rate of change represents the value of a unitary drink, in the present situation.

The coordinates of the vertices of the image of the square are S'(x, y) = (- 1, - 4), T'(x, y) = (- 1, 1), U'(x, y) = (4, 1) and V'(x, y) = (4, - 4).
How to translate a geometric locus set on a Cartesian plane
In this problem we need to make use of a translation on a geometric locus on a Cartesian plane, which is generated by four points representing the vertices of the square. The translation is a kind of rigid transformation, whose formula is shown below:
P'(x, y) = P(x, y) + t(x, y)
Where:
P(x, y) - Original pointt(x, y) - Translation vector.P'(x, y) - Resulting pointIf we know that S(x, y) = (- 6, - 5), T(x, y) = (- 6, 0), U(x, y) = (- 1, 0) and V(x, y) = (- 1, - 5) and t(x, y) = (5, 1), then the locations of the vertices of the triangle are:
S'(x, y) = (- 6, - 5) + (5, 1)
S'(x, y) = (- 1, - 4)
T'(x, y) = (- 6, 0) + (5, 1)
T'(x, y) = (- 1, 1)
U'(x, y) = (- 1, 0) + (5, 1)
U'(x, y) = (4, 1)
V'(x, y) = (- 1, - 5) + (5, 1)
V'(x, y) = (4, - 4)

Answers
Anjelah finished at 1:02 P.M. if she started at 10:15 A.M. and she took 2 hours and 47 minutes to complete it.
According to the question,
We have the following information:
Anjelah finished in 2 hours and 47 minutes.
She started at 10:15 A.M.
Now, we know that there are 60 minutes in an hour (more to know: there are 60 seconds in a minute).
So, we will add 2 hours to 10:15 A.M.:
10:15 + 2:00
12:15 P.M.
(Note that the digits before the colon gives us time in hours and the digits after the colon gives us minutes.)
Now, we will add 47 minutes to it:
12:15 + 0:47
(Now, we know that only 45 minutes can be added to 15 minutes because then it will make an hour. So, 2 more minutes will be added to the next hour.)
So, we have the following expression:
1:02 P.M.
Hence, the time when Anjelah will finish is 1:02 P.M.

Loule says the coordinate of point P is (-4,-4), while Nicky says the coordinate of point P is (2, 5). Who is correct? Describe the mistake that was made by the student who was incorrect
Answers
Using ratio and proportion, Louie is correct.
Ratio is defined as the relationship between two quantities. On the other hand, proportion is defined as the equality between two or more ratios.
From the given graph (see attached photo), the coordinates of Point F and Point G is (4, 8) and (-6, -7).
If the ratio of FP to PG is 4 to 1, then the ratio of the horizontal distance and vertical distance between the two endpoints is also 4 to 1.
FP : PG = 4 : 1
FP/PG = 4/1 = 4
x-coordinate of P
(4 - x)/(x - -6) = 4
(4 - x) = 4(x + 6)
4 - x = 4x + 24
-5x = 20
x = -4
y-coordinate of P
(8 - y)/(y - -7) = 4
(8 - y) = 4(y + 7)
8 - y = 4y + 28
-5y = 20
y = -4
Hence, the coordinates of Point P is (-4, -4).
Therefore, Louie is correct, while Nicky is mistaken probably while setting up the proportion and solving for the coordinates.

Lion, brown bear, giraffe, rhinoceros
1. How to convert kilogram to poundCoversion scale
1 kg = 2.20462
With the above scale, we can convert each measurement to pound as follow:
I. Brown bear
1 kg = 2.20462
Therefore,
272.16 Kg = 272.16 × 2.20462
272.16 Kg = 600 pounds
II. Giraffe
1 kg = 2.20462
Therefore,
1124.0 Kg = 1124.0 × 2.20462
1124.0 Kg = 2478 pounds
III. Lion
1 kg = 2.20462
Therefore,
226.8 Kg = 226.8 × 2.20462
226.8 Kg = 500 pounds
IV. Rhinoceros
1 kg = 2.20462
Therefore,
1587.6 Kg = 1587.6 × 2.20462
1587.6 Kg = 3500.1 pounds

From the graph, we have the following points
(x, y) = (10, 313) and (20, 626)
The average rate of change is the slope of the function and the average rate of change is calculated as
Average rate = [f(b) - f(a)]/[b - a]
Where
(a, f(a)) = (10, 313) and (b, f(b)) = (20, 626)
Substitute the known values in the above equation

Using the angle of elevation, the height of the tree is 71.57 feet.
How to find the height of the tree using angle of elevation?The angles of elevation to a nearby tree from a point on the ground is measured to be 54 degrees.
The distance from the tree to the point on the ground is 52 feet.
The height of the tree can be found as follows:
The situation can be modelled to a right triangle.
Therefore, the height of the tree is the opposite side of the right triangle formed.
Hence,
tan ∅ = opposite / adjacent
where
∅ = angle of elevation
tan 54 = h / 52
cross multiply
h = 52 tan 54
h = 52 × 1.37638192047
