Claim - The vertical pillars represent a state that has ratified the new government.
Evidence - The evidence is given in the document itself and is reflected in the cartoon. See the image attached.
Reasoning - The Massachusetts Centinel, August 2, 1789, "The Federal Pillars," via Library of Congress. The Massachusetts Centinel published a series of cartoons illustrating the Constitution's ratification. Each vertical pillar indicates a state that has approved the new administration.
When was the US Consitution Fully Ratified?The Constitution became the formal structure of the government of the United States of America on June 21, 1788, when New Hampshire became the ninth of 13 states to ratify it.
The Constitution has been revised 27 times, the most recently in 1992, despite the fact that over 11,000 modifications have been suggested since 1789. Article V of the Constitution specifies two procedures for proposing revisions to the document.

Brief history of triangle numbers
What is Triangle Number?
An equilateral triangle-shaped group of objects is counted using a triangular number or triangle number. Square and cube numbers are two further examples of figurate numbers, which also include triangle numbers.
Students are typically introduced to triangular numbers through the account of Carl Gauss, a well-known mathematician who used the concept of the triangle number formula to aid him with summing consecutive integers as a student. This tale and its applications in many situations are discussed in the article Clever Carl.
Triangular numbers were created by the Pythagoreans, who discovered connections between geometric forms and numbers, giving rise to triangular, square, pentagonal, and other numbers.
After four or five terms, students may recognize that the answer can be discovered by adding consecutive terms, according to our research. As an illustration, you may use the formulas 1+2+3+4+5 or 10 (the preceding term) + 5 to determine the fifth term. However, when students attempt to transition from this to the general formula for triangle numbers of
n(n+1)/2
Drawing triangle numbers is an exercise that could be helpful in establishing a connection between these two concepts.
The nth term and substitution into algebraic expressions can then be discussed using this formula. Sequences, notably quadratic sequences, can also be discussed.

A Christmas tree is supported by a wire that is 3 meters longer than the height of the tree. The wire is anchored at a point whose distance from the base of the tree is 21 meters shorter than the height of the tree. What is the height of the tree?
Answers
The height of the Christmas tree is 12 meters
How to determine the height of the Christmas tree?Represent the height of the tree with h
So, we have the following parameters
Tree height = hBaseline = h - 21Anchor = h + 3The figure that illustrates the above parameters is added as an attachment
From the figure, we have the following equation by Pythagoras theorem
(h + 3)² = h² + (h - 21)²
Expand the exponents
h² + 6h + 9 = h² + h² - 42h + 441
Evaluate the like terms
6h + 9 = h² - 42h + 441
So, we have
h² - 48h + 432 = 0
Expand
h² - 36h - 12h + 432 = 0
Factorize the equation
(h - 36)(h - 12) = 0
Solve for h
h = 36 and h = 12
When h = 36, the baseline will be negative
So, we make use of h = 12
Hence, the tree has a height of 12 meters

Answers
The vertex is the turning point of a function while the range is the interval of the value of the function thus vertex of the given function is at (-4,0) while the range is [0,6].
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
As per the given function,
x f(x) −5 1 −4 0 −3 1 −2 2 −1 3 0 4 1 5 2 6
The graph of this function has been plotted below,
The vertex is the point where the function is changing its sign of slope or turning point.
It is clear that at (-4,0) it is changing its slope of sign therefore (-4,0) will be the vertex.
The range is the interval where the function exists since the given function goes from y = 0 to y = 6 so [0,6] will be the range of the function.
Hence "The vertex is the turning point of a function while the range is the interval of the value of the function thus vertex of the given function is at (-4,0) while the range is [0,6]".

Answers
Find the area of each room and then add the three areas.
[tex]\begin{gathered} 10\times12=120 \\ 13\times15=195 \\ 12\times12=144 \\ \\ 120+195+144=459 \end{gathered}[/tex]The total square footage to be covered is 459.
Part 2)Since each square yard has 9 square feet, divide the square footage by 9 to find how many yards is that equal to:
[tex]\frac{459}{9}=51[/tex]Then, the area is equal to 51 square yards.
Part 3)The cost for each square yard is $25.56. Multiply that amount by 51 to find the total cost:
[tex]25.56\times51=1303.56[/tex]The total cost for the carpeting is $1303.56.
Part 4)Each roll of padding has 30 square yards. Since 51 yards must be covered, and two rolls would yield 60 square yards, then, the minimum amount of rolls needed is 2.
The cost for 2 rolls would be 2*$99 = $198.
Part 5)Add the cost of the two rolls of padding and the carpeting job to find the total cost:
[tex]\text{ \$}198+\text{ \$}1303.56=\text{ \$}1501.56[/tex]Then, the total cost of the carpeting job including the carpet and padding would be $1501.56.

Answers
A percentage is a number or ratio that represents a fraction of 100.
If there is a trade discount of 45% on the price of the merchandise of $5900, the net price of the merchandise is $3245.
What is a percentage?A percentage is a number or ratio that represents a fraction of 100.
We have,
Merchandise price = $5,900
Discount rate = 45%
45% = 45/100 = 9/20
The net price of the merchandise:
= 5900 - (45% of 5900)
= 5900 - 9/20 x 5900
= 5900 - 9 x 295
= 5900 - 2655
= 3245
Thus,
If there is a trade discount of 45% on the price of the merchandise of $5900, the net price of the merchandise is $3245.

What is probability?
Probability is a discipline of mathematics that deals with statistical models of how probable an event is to exist or how likely a statement is to be true. The probability of an occurrence is a value between 0 and 1 and 1, where 0 denotes the event's impossibility and 1 represents certainty. The greater the likelihood of an occurrence, the more probable it will occur. Tossing a fair (unbiased) coin is a basic example. Because the coin is fair, the two possibilities ("heads" and "tails") are equally likely; the chance of "heads" equals the probability of "tails," and because no other outcomes are possible, the probability of either "heads" or "tails" is 1/2.
The probability of having female baby is = 284/(284 + 15) = 0.95

Using a linear function, it is found that:
a) Sales are increasing at a constant rate of 30 purchases/month.
b) The linear function is: p = S(t) = 30t + 3990.
c) The total purchases will be of 5130 in June 2010.
d) The sales will be of 5400 in March of 2011.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, we have that:
The reference month is of April 2007, hence the intercept is of b = 3990.In 16 months, from April of 2007 to August of 2008, sales increased to 4470, hence the slope is given by: m = (4470 - 3990)/16 = 30.The slope of 30 is the constant rate of purchases per month, and the linear function is given by:
p = S(t) = 30t + 3990.
June 2010 is 3 x 12 + 2 = 38 months after April 2007, hence the purchases will be of:
S(38) = 30 x 38 + 3990 = 5130.
The sales will be of 5400 in t months after April 2007, for which:
S(t) = 5400
Hence:
30t + 3990 = 5400
t = (5400 - 3990)/30
t = 47 months.
One month shy of four year, hence in March of 2011.

x -9y =3/4
-9y = 3/4 -x
9y = 3/4 +x Divide both sides by 9
y = 1/12 + x/9
y= x/9 + 1/12
2) Since we have the slope 1/9, then we can write the first equation as
y= 1/9x On the same line
y= 1/9x +2/24 2/24 is a multiple of 1/12, therefore on the same line
y = 1/9x + 3/36 3/36 is a multiple of 1/12, therefore on the same line
