Answer:
m∠E = 113
Step-by-step explanation:
Given that ΔDEF ≅ ΔPQR
We know that the following angles are congruent
∠D ≅ ∠P
∠E ≅ ∠Q
∠F ≅ ∠R
Now how do we know how these angles are congruent?
Well because if a triangle statement is given and the two triangles are congruent we can infer that the angles (in order) are congruent
Meaning: because D and P are the first letters of each triangle in the statement they have congruent angles if that makes sense.
So we are also given that
∠R = 13 and ∠D = 54
and we need to find ∠E
Remember like stated previously ∠R ≅ ∠F so ∠F = 13°
Now that we have found two angles in the triangle ΔDEF we can find the missing angle (∠E)
Using the triangle angle rule (the angles in a triangle add up to equal 180)
so ∠E = 180 - ∠D - ∠F
now we plug in the given information
∠E = 180 - 54 - 13
180 - 54 = 126
126 - 13 = 113
so ∠E = 113

The length of a rectangle exceeds its width by 3 and a half feet. The area of the
rectangle is 65 square feet. Find its length.
Answers
Answer:
19.25 feet
Step-by-step explanation:
Let x be the width of the rectangle in feet. Then, the length of the rectangle is x + 3.5 feet. Since the area of a rectangle is equal to its length times its width, we know that the area of the rectangle is (x + 3.5) * x = 65 square feet.
We can solve for x by setting up the equation (x + 3.5) * x = 65 and then solving for x. This gives us the following:
x^2 + 3.5x - 65 = 0
To solve this quadratic equation, we can use the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
In this case, a = 1, b = 3.5, and c = -65, so we have:
x = (-3.5 +/- sqrt(3.5^2 - 4(1)(-65))) / 2(1)
Solving for x, we get:
x = (-3.5 +/- sqrt(12.25 + 260)) / 2
Therefore, the width of the rectangle is x = (-3.5 +/- 19.25) / 2 = -0.75 or 15.75 feet. Since the length of the rectangle is x + 3.5 feet, this means that the length of the rectangle is (-0.75 + 3.5) feet or (15.75 + 3.5) feet, which is equal to 2.75 feet or 19.25 feet.
However, we know that the length of the rectangle must exceed its width by 3.5 feet, so the only solution that is physically possible is x = 15.75 feet and the length of the rectangle is 19.25 feet. Therefore, the length of the rectangle is 19.25 feet.

The length of a leg of an isosceles right triangle can be found using the concept of Pythagoras' theorem by the formula sqrt (hypotenuse ^ 2 / 2) = x.
Since, two sides of an isosceles triangle are equal, let us consider the two equal sides as 'x' and let the hypotenuse of the triangle be 'h'.
Being a right triangle, by Pythagoras' theorem,
h ^ 2 = x ^ 2 + x ^ 2
h ^ 2 = 2x ^ 2

The leading coefficient is the number that appears before the variable with the highest exponent in a polynomial. It can be either a positive or a negative number.
The leading coefficient is the coefficient, or number, that appears before the variable with the highest exponent in a polynomial. This coefficient helps determine the end behavior of a graph, which means it can either be a positive or a negative number. For example, if the leading coefficient is a positive number, then the graph will have an upward trend on either side of the y-axis, or the x-axis. If the leading coefficient is a negative number, then the graph will have a downward trend on either side of the y-axis, or the x-axis. Additionally, the leading coefficient can also help determine the degree of a polynomial. For example, the leading coefficient of a polynomial with a degree of two will always be a positive number, while the leading coefficient of a polynomial with a degree of three will always be a negative number. In conclusion, the leading coefficient can be either a positive or a negative number and plays an important role in determining the end behavior of a graph and the degree of a polynomial.

What is â…” equal to?
Answers
The fractional notation ¾ is equal to 0.75.
â…” is a fractional notation that refers to the fraction 3/4, which is equal to 0.75. To understand this fraction, the denominator (bottom number) must be multiplied by the numerator (top number). In this case, 4 multiplied by 3 is equal to 12. Then, divide the numerator by the denominator to find the fractional value. In this example, 3 divided by 4 is equal to 0.75, which is the same as 3/4.
The formula for finding a fractional value is:
Fractional Value = Numerator / Denominator
To calculate the fractional value of 3/4, the numerator is multiplied by the denominator to get 12. Then, the numerator is divided by the denominator to get the fractional value:
Fractional Value = 3 / 4
Fractional Value = 3 * 4 / 4
Fractional Value = 12 / 4
Fractional Value = 0.75

Graph the equation on the coordinate plane. y= −4/5x Select two points on the line to graph the line.
Answers
To graph the equation y= −4/5x on the coordinate plane, we can plot two points that satisfy the equation and then draw a straight line through those points. For example, we could choose the points (-1, 4/5) and (2, -8/5), which both satisfy the equation. To plot these points, we first locate the point (-1, 4/5) on the coordinate plane. This point is 1 unit to the left of the y-axis, and 4/5 units above the x-axis. We can then draw a straight line through this point and the point (2, -8/5), which is 2 units to the right of the y-axis and 8/5 units below the x-axis. This line will be the graph of the equation y= −4/5x.

How do you write less than 70?
Answers
We can write 'less than 70' as < 70, using the less-than sign.
The less-than sign is a mathematical symbol that denotes an inequality between two values. The widely adopted form of two equal-length strokes connecting in an acute angle at the left, <, has been found in documents dated as far back as the 1560s. In mathematical writing, the less-than sign is typically placed between two values being compared and signifies that the first number is less than the second number. Examples of typical usage include 1⁄2 < 1 and −2 < 0.
Since the development of computer programming languages, the less-than sign and the greater-than sign have been repurposed for a range of uses and operations.

What values of both x and θ develop the maximum possible moment at A? Compute this moment. Neglect the size of the pulley at B.
Answers
As per the given suspended mass, the function that makes values of both x and θ develop the maximum possible moment at A is written as 14715 Nm (clockwise)
While looking into the given question, we have identified the following values, adjusted for any angle 00 ≤ θ ≤ 900 any extension 0 ≤ x ≤ 5 m.
Now, Let us consider an equation to calculate the moment using θ and x as variables around point A.
=> ((9−1.5) + x) (cosθ) (120) (9.81)
When we simplifying the given equation gives us:
=> MA = (7.5+x) 1177.2 cosθ
Here the maximum moment will develop if θ = 0 and x=5 m.
Now, by substituting these values gives us:
=> MA=(7.5+x)1177.2cosθ
=> MA=(7.5+5)1177.2cos00

Let x represent the relative location of the spider and fly, where x = 0 when they are in the same position, x = -1 when the spider is one unit away from the fly, x = -2 when the spider is two units away from the fly, and so on. The Markov chain is then given by the following transition probability matrix:
