The area of the square, which has an apothem measuring 2.5 cm and a perimeter of 20 cm is 25 cm².
What is the area of square?Area of square is the square of its side's length. It can be given as,
[tex]A=a^2[/tex]
Here, (a) is the length of the side of the square
A square has an apothem measuring 2.5 cm and a perimeter of 20 cm. The perimeter of the square is 4 times the sides of the square.
Let suppose the side of this square is a cm. thus,
[tex]4a=P\\4a=20\\a=\dfrac{20}{4}\\a=5\rm\; cm[/tex]
The area of the square is,
[tex]A=5^2\\A=25\rm\; cm^2[/tex]
Hence, the area of the square, which has an apothem measuring 2.5 cm and a perimeter of 20 cm is 25 cm².

An equation is formed of two equal expressions. The missing pieces of the solution of the quadratic equation are 50, 3, and -8.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
To fill the missing piece of the solution of the quadratic equation, you need to balance each of the equations. Therefore, the solution to the problem can be written as,
[tex]-32 = 2(x^2 + 10x)\\\\-32 + 50 = 2(x^2 + 10x + 25)\\\\18 = 2(x + 5)^2\\\\9 = (x + 5)2\\\\\pm 3= x + 5\\\\x = -2\ \ {\rm or}\ \ x = -8[/tex]

Hannah is experimenting with a new drawing program on her computer. She created quadrilateral MATH with coordinates M(1, 2). A(-5, 3), T(- 6,-3), and H(0,- 4). Hannah believes that she has created a square. Prove that Hannah is correct.
Answer:
It is a square, Hannah is a G.
Step-by-step explanation:
You can plug it in for visual, see attachment. You can see that it is a bit rotated square.
But real proof should be done with the points.
For it to be square all sides need to equal each other.
What's the x distance of M and A?
It is 1-(-5) = 1+5 = 6
What is the x distance of H and T?
It is 0-(-6) = 0+6 = 6
What is the y distance of M and H?
It is 2-(-4) = 2+4 = 6
What is the y distance of A and T?
It is 3-(-3) = 3+3 = 6
All are 6 so all sides are equal so it is a square.

Can you help finish my trigonometry maze?? And show me the equation for each I know some of them are finding angles and I’m stuck please help.
Using the trigonometric ratios of sine, cosine and tangents will help solve navigate the maze.
What is trigonometry?Trigonometry is the study of the relationships between side lengths and angles of triangles.
The three main trigonometry functions are sine, cosine and tangent.
For right-angled triangles, the ratios of the three trigonometric functions are:
Sine = opposite/hypotenuseCosine = adjacent/hypotenuse Tangent = opposite/adjacentFor the given maze, the missing measures are found using the angles and the side given.
For example:

A paper company needs to ship paper to a large printing business. The paper will be
shipped in small boxes and large boxes. Each small box of paper weighs 50 pounds
and each large box of paper weighs 80 pounds. A total of 19 boxes of paper were
shipped weighing 1280 pounds altogether. Determine the number of small boxes
shipped and the number of large boxes shipped.
Answer:
x = 8
y = 11
Step-by-step explanation:
Total small box weight = 50x [x being the number of small boxes]
Total large box weight = 80y [y being the number of large boxes]
Total boxes = x+y = 19
Total weight = 1280
Determine x and y.
You know 2 equations. One for weight and another for number of boxes each.
1280 = 50x +80yx+y = 19Rewrite second equation:
x+y=19
y=19-x
You have to plug in one into another.
1280 = 50x + 80(19-x)
Solve for x
1280 = 50x + 1520 - 80x
-240 = -30x
x = 8
Solve for y by plugging in x into one of the equations:
8+y = 19
y = 11

Step 1: Determine what negative association is
Negative association basically means that the best-fit line for the scatter plot would be in a downwards slope which means that it has a negative association.
In the given examples, Option A wouldn't work because we can see that the best-fit line would be going up which is a positive association. Option B would work because we see the downward slope. Option C wond't work for the same reason as Option A. And finally Option D would work since we have a downward slope.

Answer:
37.8579
This value is approximate and rounded to four decimal places
===============================================
Explanation:
The tangent function is being applied to some unknown angle x. To isolate x, we undo whatever tangent is doing. So we apply the inverse function. Specifically the inverse tangent function. This is also known as "arctangent" and your calculator most likely shows it as a button with a "-1" exponent above the "tan"
So apply the arctangent to both sides to get
tan(x) = 0.7773
arctan(tan(x)) = arctan(0.7773)
x = 37.8579

How to subtract mixed numbers with unlike denominators?.
To subtract mixed numbers with different denominators, follow these steps:
1. Rename the fractions using a common denominator.
2. Subtract whole numbers from whole numbers. You might need to regroup first.
3. Subtract fractions from fractions.
4. Simplify, if needed.
Let's try it with [tex]2\frac{3}{5}-1\frac{1}{4}[/tex]
First, rename the fractions using a common denominator. The least common denominator of these fractions is 20. Multiply to make equivalent fractions with 20 as the denominator.
[tex]\frac{3x4}{5x4}=\frac{12}{20}[/tex] [tex]\frac{1x5}{4x5}=\frac{5}{20}[/tex]
Rewrite the problem and subtract the whole numbers.
[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{?}{?}[/tex]
Now, subtract the fractions. Subtract the numerators and keep the denominator the same.
[tex]2\frac{12}{20}-1\frac{5}{20}=1\frac{7}{20}[/tex]
This answer is already in its simplest form, so there is no need to simplify it.
