The length of one side of the pool is 12 feet
The shape of the pool is a square
A square is a 2-dimensional quadrilateral with sides of equal lengths.
Characteristics of a square
The angles in the square are right angles
The sum of angles equal 360 degrees
Diagonals are equal in length
Area of a square = length²
144 = length²
In order to determine the length of a side, determine the square root of the area
√144 = 12 feet
therefore the area of a gym is 12 feet.

The amount Nicole's mother owe her for babysitting is 9.48 dollars.
How to find the amount Nicole mother is owing after the order?She ordered a volleyball for $9.75, a net for $29.99, and knee pads for $15.00.
Nicole's mother said that she would pay for the order on her credit card if Nicole gave her the money.
Nicole gave her mother $40.00 .
Her mother also applied the money that she owed Nicole for babysitting.
Nicole's mother then gave her back $5.26.
The amount Nicole's mother owe her for babysitting can be calculated as follows;
Therefore, the total amount for the order is
$9.75 + $29.99 + $15.00 = $54.74
let the money her mother owes her = x
Therefore,
x + 40 + 5.26 = 54.74
x = 54.74 - 40 - 5.26
x = 54.74 - 45.26
x = 9.48
Therefore, the amount Nicole's mother owe her for babysitting is 9.48 dollars.

The best function to model this data is a linear function.
We have the data:

From the table, we see that,
The slope of the points are given by:
(- 0.5 + 1) / (1 - 0) = 0.5 / 1 = 0.5
(0 + 0.5) / (2 - 1) = 0.5
(0.5 - 0 ) / (3 - 2) = 0.5
(1 - 0.5) / ( 4 - 3 ) = 0.5

and E(31, 1). The center of the circle, C, is the
midpoint of the diameter.
Part A
What is the length of the radius DC in units?
Part B
What are the coordinates of the center of the
circle?
The length of the radius DC (or EC) in units is 20 units and the coordinates of the center C of the circle is (19, 17) using concept of Coordinate Geometry and Lines.
As per the question statement, The diameter of a circle has endpoints D(7, 33) and E(31, 1). The center of the circle denoted by C, is the midpoint of the diameter. We are supposed to find the length of the radius DC (or EC) in units and the coordinates of the center C of the circle
Now using the distance formula in Line concept and coordinate geometry,
Distance between two points is given by d = √{(x2-x1)^2+(y2-y1)^2}
Given coordinates of D are (7, 33) and E are (31, 1)
Therefore Distance DE = √{(31-7)^2 + (1-33)^2}
DE = √{(576)+(1024)}
DE = √1600
DE = 40 units
Therefore, length of diameter DE is 40 units so length of radius DC (or EC) will DE/2 = 40/2 = 20 units
Now using Mid Point Formula of Line concept and coordinate geometry,
Mid Point of line joining two points is given by
C = ({x1 + x2}/2, {y1 + y2}/2)
C = ( {31+7}/2 , {1+33}/2)
C = (19, 17)

Determine whether the vectors in each pair are normal to each other. (0.8 -0.6) [0.3 0.4]
Since their dot product is equal to zero, then vectors (0.8, -0.6) and (0.3, 0.4) are normal to each other.
Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.
These two vectors are also called orthogonal to each other.
Let u = (u₁, u₂) and v = (v₁, v₂), then the dot product u . v is defined as:
u . v = u₁v₁ + u₂v₂
To check whether the vectors are normal to each other, let us check their dot product.
The given vectors are: (0.8, -0.6) and (0.3, 0.4).
Let u = ((0.8, -0.6) and v = (0.3, 0.4), then,
u . v = 0.8 . 0.3 + (-0.6) . 0.4

1 Name a linear pair. Describe the relationship of their measurements.
Answer:
Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles.
Step-by-step explanation:
If there is a pair of adjacent angles, then this pair is a linear pair if the sum of the (measures of the) two angles will be 180°. So, linear pair of angles always add up to 180°. For example, the linear pair of 30° is 150°, the linear pair of 70° is 110°, etc.
These two angles form a linear pair. We have found all four linear pairs of angles. The four linear pairs formed by the intersecting lines ←→QR Q R ↔ and ←→ST S T ↔ are ∠SOQ ∠ S O Q and ∠QOT ∠ Q O T , ∠QOT ∠ Q O T and ∠TOR ∠ T O R , ∠TOR ∠ T O R and ∠ROS ∠ R O S , and ∠ROS ∠ R O S and ∠SOQ ∠ S O Q .
What is the slope of this line?
Answer:
-1/5
Step-by-step explanation:
First:
Calculate the rise:
On this graph we go down 1 meaning our rise will be -1.
Second:
Calculate the run:
On the graph we go right 5 so the run would be 5.
Third:
We put the rise and run together to get the slope.
Hence, the answer is -1/5
Notes:
Rise means how many units you move up or down from point to point.
Run means how far left or right you move from point to point.
Up and Right= + outcome
Down and Left= - outcome
Also if your rise over run is the same number but two negative number the slope would turn into a positive.

What is Area of rectangle?The area occupied by the rectangle within its perimeter can be calculated using the formula for the area of a rectangle.
A rectangle's area is calculated by multiplying its length by its width. Therefore, the product "l x w" is the formula for the area, "A," of a rectangle whose length and breadth are "l" and "w," respectively.
Given:
rectangle:
Length = 4 cm
width= [tex]3 \frac{1}{2}[/tex] cm
So, area of rectangle
= length x width
=4 x [tex]3 \frac{1}{2}[/tex]
= 4 x 7/2
=14 cm²
Now, area of Hexagon
= 3√3/2 x a²

B: 40 divided by c = 2 times 5
C: 2 times 5 times 40= c
D: 40 divided by 5 times 2= c
E: 40 divided by (5 times 2)= c
Answer: Select all the equations you can use to find the number of basketball courts, c is = 4.
Step-by-step explanation:
Given data,
Number of players on the basketball court in a city = 40
Number of teams on each court = 2
Number of players on each team = 5
Find all the equations you can use to find the number of basketball courts, 'c'.
So, we can solve it all equations,
Then,
We select equation A :
Equation A is : c times 2 times 5= 40
We can write,
Equation A is : cx2x5 = 40
simplify equation,
c x 2 teams x 5 players = 40players
We can write,
cx2x5 = 40
cx10 = 40
c = 40/10
c = 4
Therefore, equation A use the number of basket ball courts c is = 4.
We select equation B :
Equation B is : 40 divided by c = 2 times 5
We can write,
Equation B is : 40/c = 2x5
simplify equation,
40 players / c = 2 teams x 5 players
We can write,
40/c = 2x5
40/c = 10
40 = 10c
c = 40/10
c = 4
Therefore, equation B use the number of basket ball courts c is = 4.
We select equation C :
Equation C is : 2 times 5 times 40= c
We can write,
Equation C is : (2 x 5) 40 = c
simplify equation,
(2 teams x 5 players ) 40 players = c
(2 teams x 5 players ) = 40 players divided by c
We can write,
( 2 x 5 ) = 40/c
10 = 40/c
c = 40/10
c = 4
Therefore, equation C use the number of basket ball courts c is = 4.
We select equation D :
Equation D is : 40 divided by 5 times 2= c
We can write,
Equation D is : 40/5x2 = c
simplify equation,
40 players / 5 players x 2teams = c
We can write,
40/5x2 = c
40/10 = c
4 = c
c = 4
Therefore, equation D use the number of basket ball courts c is = 4.
We select equation E :
Equation E is : 40 divided by (5 times 2)= c
We can write,
Equation E is : 40/5x2 = c
simplify equation,
40 players / 5 players x 2 teams = c
We can write,
40/5x2 = c
40/10 = c
4 = c
c = 4
Therefore, equation E use the number of basket ball courts c is = 4.
Therefore,
select all the equations you can use to find the number of basketball courts, c is = 4.
