The perimeter of the trapezoid ABFE and the prove that the triangle ΔABC is an isosceles are as follows;
First question;
The perimeter of the trapezoid ABFE is 100 units
Second question;
The sides AB and BC in the triangle ΔABC are congruent, therefore, triangle ΔABC is an isosceles triangle
What is an isosceles triangle?An isosceles triangle is a triangle that has two sides that have the same lengths.
The specified parameters are;
The segment joining the midpoints of the side [tex]\overline{AC}[/tex] and [tex]\overline{BC}[/tex] of the equilateral triangle ΔABC = EF
EF = 2·x + 8 and AB = 7·x - 2
The midsegment theorem applied to the triangle ΔABC indicates that we get;
EF = (1/2) × AB
Therefore; 2·x + 8 = (1/2) × (7·x - 2)
(1/2) × (7·x - 2) = 2·x + 8
7·x - 2 = 2 × (2·x + 8)
7·x - 2 = 4·x + 16
7·x - 4·x = 16 + 2 = 18
3·x = 18
x = 18/3 = 6
x = 6
EF = 2·x + 8
Therefore; EF = 2 × 6 + 8 = 20
EF = 20
AB = 7·x - 2
Therefore; AB = 7 × 6 - 2 = 40
AB = 40
AB = AC = BC (Definition of an equilateral triangle)
Therefore;
AC = BC = AB = 40 (symmetric property)
The midpoints E and F, indicates that we get;
AE = CE and BF = CF
AC = AE + CE and BC = BF + CF (segment addition property)
Therefore; AC = AE + AE = 2 × AE
40 = 2 × AE
AE = 40/2 = 20
BC = 2 × BF
40 = 2 × BF
BF = 40/2 = 20
The perimeter of the trapezoid ABFE, P = AB + BF + EF + AE
P = 40 + 20 + 20 + 20 = 100
The perimeter of the trapezoid ABFE = 100 unitsSecond question
The coordinates of the vertices of the triangle are;
A(1, 2), B(-5, 3), and C(-6, -3)
The lengths of the sides of the triangle found using the distance formula are;
AB = √((-5 - 1)² + (3 - 2)²) = √(37)
BC = √((-6 - (-5))² + (-3 - 3)²) = √(37)
AC = √((-6 - 1)² + (-3 - 2)²) = √(74)
The lengths of the sides AB and BC in the triangle ΔABC are the same, therefore, the triangle ΔABC is an isosceles triangle.

Sam does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at least 10 hours. He spends at most 7 hours doing cardiovascular work. He spends at most 6 hours on weight training. Let × denote the time (in hours) that Sam spends doing cardiovascular work.
Let y denote the time (in hours) that he spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.
So, in response to the above question, we can state that We obtain the inequality following system of inequalities by combining these three constraints:
[tex]x + y \geq 10\\x \leq 7\\y \leq 6[/tex]
What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.
[tex]x + y \geq 10[/tex]
Next, we know that Sam works out his cardiovascular system for no more than 7 hours. Thus, x must be less than or equal to 7. This restriction can be shown by the inequality:
[tex]x \leq 7[/tex]
Finally, we are aware that Sam only devotes a maximum of 6 hours to weight training. This implies that y should be between -6 and -6. This restriction can be shown by the inequality:
[tex]y \leq 6[/tex]
We obtain the following system of inequalities by combining these three constraints:
[tex]x + y \geq 10\\x \leq 7\\y \leq 6[/tex]

Seshni wants to cover six cushions, each measuring 36 cm x 36 cm, with fabric. She adds 1.5 cm extra for each seam. The fabric she wants to buy is 90 cm wide and costs R59,99/m excluding VAT. How much fabric must be bought to cover all six cushions? How much will the fabric cost, including VAT?
If Seshni wants to cover six cushions, each measuring 36 cm x 36 cm, with fabric.
a. Seshni needs to buy 0.84375 square meters of fabric.
b. It will cost R64.66 including VAT.
How to find the fabric cost ?a. The dimensions of each cushion are 36 cm x 36 cm, and with the added 1.5 cm seam allowance, each cushion will require fabric with dimensions of (36 + 1.5) cm x (36 + 1.5) cm = 37.5 cm x 37.5 cm.
The total area of fabric required to cover all six cushions is:
6 cushions x (37.5 cm x 37.5 cm) = 8437.5 square centimeters
To convert to square meters, we need to divide by 10000:
8437.5 square centimeters / 10000 = 0.84375 square meters
So, Seshni needs to buy 0.84375 square meters of fabric.
b. Next, we can calculate the cost of the fabric.
0.84375 square meters / 0.9 meters = 0.9375 meters
The cost per meter is R59.99 excluding VAT, so the cost of the fabric is:
0.9375 meters x R59.99/meter = R56.23
To calculate the cost including VAT, we need to add the VAT amount. Assuming the VAT rate is 15%, the VAT amount is:
0.15 x R56.23 = R8.43
So the total cost including VAT is:
R56.23 + R8.43 = R64.66
Therefore, Seshni needs to buy 0.84375 square meters of fabric, and it will cost R64.66 including VAT.

Step-by-step explanation:
what is 36 cube root?
The cube root of 36 is a number between 3 and 3.5, and can be represented mathematically as ∛36.
Square roots are simply the opposite operation of squaring a number. For example, the square root of 9 is 3 because 3 x 3 = 9.
Similarly, the cube root is the opposite operation of cubing a number. The cube root of a number is the value that, when cubed, gives the original number. For instance, the cube root of 27 is 3 because 3 x 3 x 3 = 27.
Now, to answer your question, "What is 36 cube root?" - this can be written as ∛36 or as the cube root of 36. To find the cube root of 36, we need to find a number that, when cubed, gives 36.
We can start by using trial and error. We know that 2 x 2 x 2 = 8, which is less than 36. We also know that
=> 3 x 3 x 3 = 27, which is less than 36.
So, we can try a number between 3 and 4. Let's try 3.5.
If we cube 3.5, we get 42.875, which is greater than 36.
If we try a number lower than 3.5, we will get an even greater value. Therefore, the cube root of 36 is between 3 and 3.5.
We can use more precise methods to find the cube root of 36, such as using a calculator or estimating with decimal approximations. However, using trial and error is a simple and effective way to find an approximate answer.

which theorem or postulate proves that △abc and △def are similar?
To prove that two triangles △ABC and △DEF are similar, we can use the following theorem:
The Angle-Angle (AA) Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
Or else, if ∠A ≅ ∠D and ∠B ≅ ∠E, then △ABC ~ △DEF. This theorem relies on the fact that when two angles of one triangle are congruent to two angles of another triangle, the third angle must also be congruent due to the fact that the sum of the angles in a triangle is always 180 degrees. Thus, the triangles must have the same shape and are therefore similar.

If the whole number n is such that n * (n+28) is a prime number. the prime number is 29.
How to find the prime number?We can start by expanding the expression n × (n+28) to get n^2 + 28n. Notice that n^2 + 28n is a quadratic expression that can be factored as n(n+28). Therefore, if n × (n+28) is a prime number, then n and n+28 must be either 1 and the prime number or the prime number and 1 (since a prime number has only two positive factors, 1 and itself).
If n = 1, then n+28 = 29, and n × (n+28) = 1 × 29 = 29, which is a prime number.
If n+28 = 1, then n = -27, which is not a whole number.

Step-by-step explanation:
The total number of many sixth-grade students at Luehrs Middle School found using the percentage is 320.
What is meant by percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. There is no dimension to percentages. As a result, it is known as a dimensionless number.
Given,
Number of students in sixth grade who has a pet dog = 112
The percentage of sixth grade students who has a pet dog = 35%
Let the number of total sixth grade students be x.
Percentage
= (Number of students with pet dog/Total number of sixth grade students * 100
35 = (112/x) * 100
35/100 = 112/x
x = (100/35) * 112 = 320

Add 10 to both sides:
[tex]2x^2-10x\:+\:37\:=0[/tex]
Comparing to the standard form we see
a = 2, b = -10, c = 37
The discriminant is
[tex]b^2 - 4ac = (-10)^2 - 4\cdot2\cdot 37\\= 100 - 296\\= -196[/tex]
Since the discriminant is negative both roots will be comples
[tex]x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }\\\\x = \dfrac{ -(-10) \pm \sqrt{(-10)^2 - 4(2)(37)}}{ 2(2) }\\\\x = \dfrac{ 10 \pm \sqrt{100 - 296}}{ 4 }\\\\x = \dfrac{ 10 \pm \sqrt{-196}}{ 4 }[/tex]

What is the probability of at least one head in two coin tosses?
When tossing a fair coin, the possible outcomes are a head (H) or a tail (T), each with a probability of 1/2.
To find the probability of getting at least one head in two coin tosses, we can first find the probability of getting no heads (i.e., two tails) and then subtract that from 1 to get the probability of getting at least one head.
The probability of getting two tails is (1/2) * (1/2) = 1/4, since the probability of getting a tail on the first toss is 1/2 and the probability of getting a tail on the second toss is also 1/2, and we multiply these probabilities together to get the joint probability.
Therefore, the probability of getting at least one head in two coin tosses is:
1 - 1/4 = 3/4
So the probability of at least one head in two coin tosses is 3/4 or 0.75.

The internal angles of a hexagon may be calculated using the formula "180 - (360/n)," where n is the number of sides. When you enter 6 for a hexagon, the response is 120 degrees.
We might begin by imagining a hexagon to better comprehend the notion. It is a basic design made up of six distinct straight lines that join to form a closed shape. The internal angles are the angles on the inside of the form.
The above-mentioned formula may be used to compute the internal angles of a hexagon. For each inner angle of a hexagon, the computation yields a value of 120 degrees. Hence the total of a hexagon's internal angles is 720 degrees.

PLEASE HELP ME
What is the value of x in this triangle?
Answer:
x = 39
Step-by-step explanation:
We need to solve for the interior angle measure. The sum of a triangle's interior angle measures are 180, so we just have to create an equation and solve for x.
[tex]x+102+39=180[/tex]
Add like terms
[tex]x+141=180[/tex]
Subtract 141 on both sides
[tex]x=39[/tex]
To check our work, we can add the angle measures together to see if they add up to 180.
[tex]39+102+39 = 180[/tex]
