A triangle is shown with its exterior angles. The interior angles of the triangle are angles 2, 3, 5. The exterior angle at angle 2 is angle 1. The exterior angle at angle 3 is angle 4. The exterior angle at angle 5 is angle 6. Which statements are always true regarding the diagram? Select three options. m∠5 + m∠3 = m∠4 m∠3 + m∠4 + m∠5 = 180° m∠5 + m∠6 =180° m∠2 + m∠3 = m∠6 m∠2 + m∠3 + m∠5 = 180°
Therefore , the solution of the given problem of angles comes out to be the three propositions m∠3 + m∠4 + m∠5 = 180°, m∠5 + m∠6 = 180°, and m∠2 + m∠3 = m∠6.
An angle's meaning is what?The point of intersection of the paths joining a skew ends yields the skew's greatest and smallest walls. A crossroads may be where two paths converge. Angle is another outcome of two things interacting. They approach dihedral shapes more than anything. A two-dimensional curve can be created by arranging two line beams in various configurations between their endpoints.
Here,
Regarding the illustrated diagram, the appropriate statements are:
=> m∠3 + m∠4 + m∠5 = 180°
This is accurate since every triangle's internal angles add up to 180°.
=> m∠5 + m∠6 = 180°
This is true because a triangle's internal angle and outside angle are always equal to 180 degrees.
=> m∠2 + m∠3 = m∠6
This is accurate because, based on the information provided,
the exterior angle at angle 2 (m2) of the triangle is equal to the corresponding interior angle at angle 6 (m6) of the triangle.
Therefore, the three propositions m∠3 + m∠4 + m∠5 = 180°, m∠5 + m∠6 = 180°, and m∠2 + m∠3 = m∠6. are always true in relation to the given figure.

4. Greta's neighborhood is having a picnic to celebrate the end of the school year. She has been
asked to prepare potato salad. Greta actually has to work at 2pm when the picnic is scheduled, so
she asks Lynn, the neighbor coordinating food, if she can drop off the potato salad at the park
when she goes into work at 10am. Lynn is not sure this will work. Describe why Lynn is hesitant
and what might happen if Greta's potato salad sits out in the sun until the picnic begins at 2pm.
Then offer at least one suggestion to solve Greta and Lynn's problem.
Lynn is hesitant to allow Greta to drop off the potato salad at 10am .
How to solve Greta and Lynn's problem?Greta could make the potato salad the night before and keep it in the refrigerator to solve the problem she and Lynn were having. She could then transport the potato salad at a safe temperature in a cooler filled with ice packs on the day of the picnic.
She could ask Lynn to store the potato salad in a cooler or refrigerator until the picnic starts when she gets to the park. Along these lines, the potato salad will be protected to eat and won't represent a gamble of food contamination.
The mayonnaise in Greta's potato salad will spoil, leading to the growth of bacteria that could result in foodborne illness, if it is left outside in the sun until the picnic begins at 2 p.m. The potato salad may cause nausea, vomiting, diarrhea, and stomach cramps in those who consume it.
Because food safety guidelines state that perishable foods, like potato salad, should not be kept at room temperature for more than two hours, Lynn is hesitant to let Greta drop off the potato salad at 10 a.m.
If the potato salad is left out in the sun from 10 a.m. to 2 p.m., bacteria can grow on it, and eating it could make you sick.

Miranda is standing at the corner of a 7 m by 11 m field. She needs to go to the corner diagonally opposite from where she is standing. How much shorter is it if she cuts across the diagonal instead of walking around the perimeter of the field? Round your answer to the nearest hundredth of a meter.
Therefore, Miranda saves approximately 22.96 meters by cutting across the diagonal instead of walking around the perimeter of the field.
What is perimeter?Perimeter is the total length of the boundary or outer edge of a two-dimensional shape, such as a square, rectangle, triangle, or circle. It is the distance around the shape, and is measured in units such as centimeters, meters, feet, or inches. To find the perimeter of a shape, you simply add up the lengths of all its sides. For example, the perimeter of a square with sides of length 5 cm would be 4 × 5 cm = 20 cm. The perimeter of a rectangle with length 6 cm and width 4 cm would be 2 × (6 cm + 4 cm) = 20 cm.
If Miranda walks around the perimeter of the field, she will travel a distance equal to the perimeter of a rectangle, which can be calculated as follows:
[tex]Perimeter = 2(Length + Width) = 2(7m + 11m) = 2(18m) = 36m[/tex]
To cut across the diagonal of the field, Miranda will travel a distance equal to the length of the diagonal of the rectangle. This can be found using the Pythagorean theorem:
[tex]Diagonal = \sqrt(Length^2 + Width^2) = \sqrt(7m^2 + 11m^2) = \sqrt(170m^2) \approx 13.04m[/tex]
So, the distance Miranda saves by cutting across the diagonal is:
[tex]36m - 13.04m \approx 22.96m[/tex]
Rounding to the nearest hundredth of a meter gives:
≈ 22.96m to 2 decimal places
Therefore, Miranda saves approximately 22.96 meters by cutting across the diagonal instead of walking around the perimeter of the field.

Here, we have
Given: Triangle D has been dilated to create triangle D′.
To find the scalar value, simply choose one side of D and one did of D’ and divide them to find the scalar. We can verify that we have the correct scalar by performing this division on each related edge. Below I will do D to D’ represented like D/D’:
4.8 / 1.6 = 3
4.2 / 1.4 = 3
2.7 / x = 3
Knowing that the scaling for each edge is 3, we can solve for x.
2.7 / 3 = x
0.9 = x
The edges for D are 4.8, 4.2, and 2.7 respectively to D’ scaled by 1/3. So we can determine that the edges for D’ are 1.6, 1.4, and 0.9 respectively to D scaled by 3.
So if we go D’ to D, we scale by 3. If we go D to D’, we scale by 1/3.

Thus, the value of x and y for the given right angled triangle are found as: x = 8 and y = 2√3.
Explain about the Pythagorean theorem:The Pythagorean Theorem, a well-known geometric principle that states that the square just on hypotenuse (the side across from the right angle) of a right triangle equals the sum of the squares on its legs, is also known as the
a² + b² = c².
For the larger triangle, applying Pythagorean theorem:
4² + (4√3)² = x²
x² = 16 + 16*3
x² = 16 + 48
x² = 64
x = 8
Then, x - 6 = 8 - 6 = 2
Now applying Pythagorean theorem for smaller triangle:
y² + (x - 6)² = 4²
y² = 4² - 2²
y² = 16 - 4
y² = 12
y² = √12
y = 2√3

By answering the presented question, we may conclude that As a result, the average speed on the flat road is 57 miles per hour.
what is expression ?In mathematics, you can multiply, divide, add, or subtract. An expression is constructed as follows: Number, expression, and mathematical operator A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) It is possible to contrast expressions and phrases. An expression or algebraic expression is any mathematical statement that has variables, integers, and an arithmetic operation between them. For example, the phrase 4m + 5 has the terms 4m and 5, as well as the provided expression's variable m, all separated by the arithmetic sign +.
Let's apply the formula:
distance = time speed
The bus went for 2 hours on the level road, hence the distance travelled is:
1 distance = x 2
The bus went for 3 hours on the twisting route, hence the distance travelled is:
3 distance2 = (x - 20)
Because the bus's total distance travelled is 225 miles, we may write:
distance1 plus distance2 equals 225
Substituting distance1 and distance2 expressions yields:
x × 2 + (x - 20) × 3 = 225
When we simplify this equation, we get:
2x + 3x - 60 = 225
5x = 285\sx = 57
As a result, the average speed on the flat road is 57 miles per hour.

cost per share of the mutual fund.
The cost per share of the technology stock is $14.
What is a variable?
In mathematics, a variable is a symbol or letter that represents a value or a quantity that can change or vary in a given context or problem. Variables are used to express mathematical relationships and to formulate equations and functions.
Let's use variables to represent the cost per share of the technology stock and the mutual fund. We can call the cost per share of the technology stock "T" and the cost per share of the mutual fund "M".
From the problem, we know:
Nora bought 100 shares of the technology stock and 200 shares of the mutual fund for a total of $3600:
100T + 200M = 3600
Erin bought 300 shares of the technology stock and 50 shares of the mutual fund for a total of $5300:
300T + 50M = 5300
We now have a system of two equations with two variables. We can solve for T and M by using elimination or substitution. Here, we will use the substitution method:
From the first equation, we can isolate T by subtracting 200M from both sides:
100T = 3600 - 200M
Divide both sides by 100 to get:
T = 36 - 2M
Now substitute this expression for T into the second equation:
300(36 - 2M) + 50M = 5300
Expand and simplify:
10M = 1100
Divide both sides by 10 to get:
M = 110
So the cost per share of the mutual fund is $110.
To find the cost per share of the technology stock, we can substitute M = 110 into either of the original equations. Let's use the first equation:
100T + 200(110) = 3600
Simplify:
100T = 1400
Divide both sides by 100 to get:
T = 14
So the cost per share of the technology stock is $14.

The formula for calculating the average of given numbers is equal to the sum of all values divided by the total number of values. There are three main types of averages: mean, median, and mode. All of these techniques work slightly differently and often give slightly different typical values.
(i). Given that there are a total of 42 children on the birthday, finding the value of x:
2x + 3x (4x-1) + x + (x-2) + (x-3) = 42
11x - 6 = 42
11x = 48
x = 4
Therefore, the value of x is equal to 4.
(ii). To find the average age, we need to calculate the sum of all the ages and divide by the total number of children:
Average age = (7 x 2 + 8 x 3 + 9 x (4-1) +10 x 4 +11 x (4-2) 12 x (4-3)) / 42
= (14 + 24 + 27 + 40 + 22 +12) / 42
= 139/42
= 3.31
Rounded to the nearest whole number, the average age is 3.
(iii). The probability of randomly selecting a child under 9 is obtained by adding the number of children aged 7, 8 or 9 (because we want children under 9) and dividing by the total number of children:
Number of children under 9 years = 2x + 3x + (4x-1)
Number of children under 9 years = 9x - 1
Number of children under 9 = 9(4)–1
Number of children under 9 years = 35
Probability of choosing a child under 9 = number of children under 9 / total number of children
Probability of choosing a child under 9 = 35/42
The probability of choosing a child under 9 years old is ≈ 0.83
Thus, the probability of randomly selecting a child under the age of 9 is approximately 0.83.

The fraction of the panel, that is left after cutting out the hole is [tex]\frac{11}{12}[/tex]
What are the areas of some common plane figuresThe area of a rectangle equals the product of its 2 sides. The area of a triangle is equal to half of the product of the base and height.. If we choose one of the sides as the base, then for area calculation, for height we have to use the height of the opposite vertex from this base. To find it, we have to drop a perpendicular from the opposite vertex onto the base. The area of a parallelogram is the product of the length of the base and the perpendicular distance between the two parallel sides of the parallelogram. Area of a trapezium = half of the product of the distance between the parallel sides and the sum of the length of the parallel sides. Area of a circle is [tex]\pi r^2[/tex], in which r is the radius of the given circle. Sometimes the plane figure maynot be a standard shape. In that case we have to divide the figure into suitably many parts such that, each part is a standard figure whose area we can calculate. Also sometimes we can represent an area as the difference of the area of two standard figures. In that case to find the area we have to take the difference of the areas of the two standard figures.
In our question. Initial area of the panel is (3)(2) = 6 square ft.
Area of the cutout = (1)([tex]\frac{1}{2}[/tex]) = [tex]\frac{1}{2}[/tex] square ft.
Using the formula, fraction left = [tex]\frac{6 - \frac{1}{2}}{6} = 1 - \frac{1}{12} = \frac{11}{12}[/tex]

Required fraction left is 11/12 square feet.
What is area of rectangle?
A rectangle is a geometric shape that has four sides and four right angles. It is a type of quadrilateral and is characterized by its two pairs of parallel sides. The opposite sides of a rectangle are congruent, which means they have the same length, and the adjacent sides are perpendicular to each other.
The area of a rectangle is the total amount of space inside the rectangle and is calculated by multiplying the length of the rectangle by its width. The formula for the area of a rectangle is Area = length x width
For example, if a rectangle has a length of 6 units and a width of 4 units, the area can be calculated as:
Area = 6 units x 4 units = 24 square units
The area of the panel is 3 feet x 2 feet = 6 square feet
The area of the hole is 1 foot x 1/2 foot = 1/2 square feet
Therefore, the area left is 6 square feet - 1/2 square feet = 11/2 square feet
The fraction left is (11/2 square feet) / (6 square feet) = 11/12
Therefore, the required correct option is C.

AA Similarity Theorem is required to prove that both triangles are similar
What is AA Similarity Theorem
AA (Angle-Angle) Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
In other words, if two angles of one triangle are equal to two angles of another triangle, then the third angles must also be equal, and the two triangles are said to be similar.
One of the equal angle is marked while the other is equal using the concept of vertical angle theorem. Angles formed where the line intersect are the ones equal by vertical angle theorem

Ejercicio 2.- La temperatura ambiente a las 8 am era de 61 grados Farenheit. Fue aumentando de forma lineal hasta la 1 pm en que el termómetro marcó 81 grados. a) Escriba una ecuación lineal que muestre la temperatura en función de la hora en ese intervalo. b) Calcule con esa ecuación la temperatura a las 11:15 am. Aproxime a la décima de grado Farenheit si fuera necesario. oprondamos a hacer ecuaciones y resolver
a)Por lo tanto, la ecuación lineal que representa la temperatura en función de la hora es T(h) = 4h + 29
b) Por lo tanto, la temperatura a las 11:15 am aproximadamente es de 75.3 grados Farenheit.
what is aproximadamente ?
"Aproximadamente" is a Spanish word that means "approximately" or "roughly" in English. It is often used to indicate that a value or measurement is not exact, but rather an estimation or approximation.
In the given question,
a) La ecuación lineal que relaciona la temperatura con la hora en ese intervalo es:
T(h) = m*h + b
donde T es la temperatura en grados Farenheit, h es la hora en formato de 24 horas, m es la pendiente de la recta y b es el término independiente.
Primero encontramos la pendiente m:
m = (81 - 61) / (13 - 8) = 4
Luego, encontramos el término independiente b utilizando uno de los puntos:
61 = 4*8 + b
b = 29
Por lo tanto, la ecuación lineal que representa la temperatura en función de la hora es:
T(h) = 4h + 29
b) Para encontrar la temperatura a las 11:15 am, primero convertimos el tiempo a horas decimales:
11:15 am = 11 + 15/60 = 11.25 horas
Luego, sustituimos este valor en la ecuación lineal:
T(11.25) = 4(11.25) + 29 = 75.25
Por lo tanto, la temperatura a las 11:15 am aproximadamente es de 75.3 grados Farenheit.
