A circular rug has a circumference of 314 inches. What is the approximate area? Round to the nearest whole inch. Use 3.14 for pie 
Answer:
The area is 7850 square inches
Step-by-step explanation:
Given the circumference, we want to calculate the area
mathematically, the circumference is;
C = 2 pi r
So r is C/2 pi
Area = pi * r^2
Substitute value for r from circumference;
Area = Pi * c^2/4pi^2
Area = C^2/4pi
Area = 314^2/4 * 3.14
Area = 7850 Inches square
Answer:
7,850

The number of texts she sent in September can be represented by x.
She pays $30 per month plus $0.05 per text.
Her bill for September was $60.
What is x, the number of texts Heather sent during the month of September?
Answer: x = 500
Step-by-step explanation:
1. You turn it into 30 + 0.05x = 60
2. Subtract 30 from both sides to get 0.05x = 30
3. Then divide 30 by 0.05 and get 600
4. Write down x = 600

On the set of axes below, triangle ABC is graphed. Triangles A'B'C'
and A"B"C", the images of triangle ABC, are graphed after a
sequence of rigid motions.
Answer:
Step-by-step explanation:
a reflection followed by a rotation
The sequence of rigid motions of the triangle is a reflection followed by a rotation, option (D) is the correct answer.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. Graphs are used to map out functions of two variables on a Cartesian coordinate system, which is composed of a horizontal x-axis and a vertical y-axis.
For the given situation,
The graph shows the triangle ABC plotted in the fourth quadrant.
The triangle A'B'C' are graphed in the third quadrant as its reflection.
The triangle A''B''C'' are graphed in the second quadrant by reflecting the triangle A'B'C' and then rotating it.
Hence we can conclude that the sequence of rigid motions of the triangle is a reflection followed by a rotation, option (D) is the correct answer.

The table and graph both represent the same relationship.
Which equation also represents that relationship?
Answer:
x = 1
Step-by-step explanation:
From the table shown in the picture,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Similarly, from the graph shown,
For input value x = 1, output values of y = 2, 4, 6, 8, 10
Therefore, both will represent the same relationship.
From the graph attached, straight line parallel to y-axis is x = 1.
Therefore, x = 1 will be the correct option.

We have given that,
the factors of function f, and use them to complete this statement.
f(x)= 2x^4 - x^3 -18x^2 + 9x
What is the function?A function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.
We have to determine the factor of the given function

Six girls of differing heights are arranged in 2 rows of 3 each. Each girl is taller than the girl in front of her and also taller than the girl to her right. How many arrangements of the six girls are possible?
Answer:
5 possible ways
Step-by-step explanation:
Questions like this are a bit technical. Therefore, there are no perfect formula, all you have to do is picture the scene and count. Having said that. Let us use name the positions the girls are standing according to the question:
D E F
A B C
I have arranged this according to how the question has specified, meaning F is the tallest and A is the shortest if I take F to be at the back right and A to be at the front left.
In reality, A and F can never change their positions if we maintain the arrangement specified.
What we have left is to look for how to rearrange, D, E, B and C that will still make it fit the arrangement. Take note that E cannot be in front of B because she is taller than B.
Since positions for shortest and tallest are fixed, you are left with 4 people and you need two of them for the front position. This can be gotten using 4C2 = 6, but the two tall persons can't be in the front else it will disrupt the arrangement, so we have to eliminate that case which will occur once, therefore we have 5 possible ways we can make the arrangements as required.

Your friend claims the measure of an exterior angle will always be greater than the sum of the nonadjacent interior angles measures. Is your friend correct> Explain your reasonings.
Answer:
your friend is wrong
Step-by-step explanation:
There is a theorem in geometry called the Exterior Angle Theorem which was developed by Euclid (Greek mathematician that lived in Alexandria around 300 B.C.) that states that the exterior angle of a triangle will always equal the sum of the 2 nonadjacent interior angles.
