B) 90º, 90º, 180º, 180
C) 60º, 60º, 120º, 120º
Answer:
C) 60º, 60º, 120º, 120º
Step-by-step explanation:
We know the sum of all the angles in a rectangle is 360 degrees, whether it's irregular or not.
Given: x + 2x + 2x + x = 360
Calculate the linear equation, to find x.
x + 2x + 2x + x = 360
3x + 3x = 360
6x = 360 (Divide both sides by 6)
x = 60 degrees.
Then you can calculate the polygons.
x + 2x + 2x + x
For the first x, = 60.
Then for 2x, 60 * 2 = 120.
Then for 2x again, = 120.
Finally for the last x, = 60.
Therefore, the answer is C) 60º, 60º, 120º, 120º.
true/false. The p-value of a test is the probability of observing a test statistic at least as extreme as the one computed, given that the null hypothesis is true.
True. The p-value is a probability value that measures the power of evidence in against to the null hypothesis in a statistical test.
Mainly, it represents the possibility of staring at a test statistic as a minimum as extreme as the one computed, assuming that the null hypothesis is genuine.
If the p-value is small, commonly less than a chosen significance stage (e.g., 0.05), it shows that the determined data is unlikely to have took place by danger alone and provides proof against the null hypothesis. alternatively, a large p-value suggests that the determined information is consistent with the null speculation, and the evidence isn't sturdy enough to reject it.
Consequently, the p-value is an critical tool in statistical inference, permitting researchers to draw conclusions about the population based totally on pattern information and degree the extent of uncertainty in their outcomes.

Write two expressions to represent the following situation. Then, find the answer.
When Nathan went to bed, the outside temperature was 28°F. When he woke up the next morning, the temperature had decreased to -13°F. By how many degrees did the temperature change during the overnight hours
The temperature changed by 41°F during the overnight hours, decreasing from 28°F to -13°F.
How is an expression determined?The difference in temperature from 28°F to -13°F can be shown in one of two ways:
Temperature change equals final temperature - The starting temperatureTemperature change: (-13°F) - (28°F)Temperature change: -41°FTemperature change = final temperature minus initial temperature; temperature change = -13°F minus 28°F; temperature change = -41°F; temperature change = 41°F.To calculate the change in temperature, the first exponent equation subtracts the initial temperature from the end temperature. The change in this instance is negative and points to a drop in temperature.
The absolute value function is employed in the second statement to guarantee a positive result regardless of whether the temperature rose or fell. The result is the same as the first expression in this instance, but with a positive sign.

The height of the tree is closest to 8.66 meters (option B).
What is angle of elevation?Angle of elevation is the angle between a horizontal line of sight and an object above the line of sight, as measured from the observer's eye.
In other words, it is the angle formed between the observer's line of sight and the line drawn from the observer's eye to the object being observed, when the object is above the observer's eye level.
To solve this problem, we can use the property of similar triangles, which states that the ratios of corresponding sides of similar triangles are equal.
For the boy and his shadow, we have:
height of boy / length of boy's shadow = height of tree / length of tree's shadow
Substituting the values given, we get:
56 / 48 = height of tree / x, where x is the length of the tree's shadow
Solving for the height of the tree, we get:
height of tree = (56 / 48) * x
We are not given the length of the tree's shadow, but we can use the information given in the second part of the problem to find it.
For the tree and its shadow, we have:
height of tree / length of tree's shadow = tan(30)
Substituting the value of the length of the tree's shadow as 15 meters and solving for the height of the tree, we get:
height of tree = 15 * tan(30)
height of tree ≈ 8.66 meters

6 TH GRADE MATH , WHAT IS THE SLOPE? TY
Answer:
Step-by-step explanation:
The slope of a line is the measure of the steepness and the direction of the line. Finding the slope of lines in a coordinate plane can help in predicting whether the lines are parallel, perpendicular, or none without actually using a compass.
The slope of any line can be calculated using any two distinct points lying on the line. The slope of a line formula calculates the ratio of the "vertical change" to the "horizontal change" between two distinct points on a line. In this article, we will understand the method to find the slope and its applications.
That is what Slope is.
Answer:
Step-by-step explanation:
Slope :( 1,1)
You start on the y-axis point which is (0,1) as you can see it is going up so I used the “up left” strategy. You go up 1 to the left 1 since the line intersects at point (1,2)
How do you find the slope of (-4, 8) and (4, 2)
To find the slope of a line that passes through two points, you can use the slope formula. The slope formula is:
Slope = (y2 - y1) / (x2 - x1)
Using the points given in your question, the slope formula to find the slope of the line is:
Slope = (2 - 8) / (4 - (-4))
Using the order of operations, the calculation of the slope formula is as follows:
Slope = -6 / 8
Therefore, the slope of the line passing through (-4, 8) and (4, 2) is -3/4.

which statements are true about the reflectional symmetry of a regular heptagon? select two options. it has only 1 line of ref
the regular heptagon has only one line of reflectional symmetry, and it passes through the center of the heptagon. This property is common to all regular polygons, and it is related to their rotational symmetry.
The statements that are true about the reflectional symmetryof a regular heptagon are:
It has only one line of reflectional symmetry.
The line of reflectional symmetry passes through the center of the heptagon.
A regular heptagon is a polygon with seven equal sides and angles. Each vertex of the heptagon is equidistant from the center of the heptagon, and the lines connecting the center to the vertices divide the heptagon into seven congruent triangles.
To understand the reflectional symmetry of the regular heptagon, we need to define what it means. Reflectional symmetry is a type of symmetry where a figure is symmetric with respect to a line. In other words, if we fold the figure along this line, one half will coincide with the other half.
In the case of the regular heptagon, we can observe that if we draw a line passing through the center of the heptagon and perpendicular to any of its sides, we obtain a line of reflectional symmetry. This line divides the heptagon into two congruent halves. However, if we draw any other line of reflectional symmetry, it will not coincide with the sides of the heptagon, and therefore, it will not divide the heptagon into congruent halves.
Therefore, we conclude that the regular heptagon has only one line of reflectional symmetry, and it passes through the center of the heptagon. This property is common to all regular polygons, and it is related to their rotational symmetry.

Mia has a collection of vintage action figures that is worth $190. If the collection appreciates at a rate of 6% per year, which equation represents the value of the collection after 5 years?
The equation that represents the value of the collection after 5 years is:
Value of collection after 5 years = 190 x (1 + 0.06)^5
Explanation:
To calculate the value of the collection after 5 years, we need to use the compound interest formula. This formula is represented as A = P x (1 + r)^n, where P is the principal amount (initial value of the collection), r is the rate of interest (in this case, 6%), and n is the number of years (in this case, 5).
Therefore, the equation for the value of the collection after 5 years is:
Value of collection after 5 years = 190 x (1 + 0.06)^5
This can also be written as:
Value of collection after 5 years = 190 x 1.31 (1.31 is the result of (1 + 0.06)^5)
Therefore, the value of the collection after 5 years is $246.90.

The rate at which the distance between the car and the truck is changing when the car is 9 m from the intersection and the truck is 40 m from the intersection is about 19.187 m/s
What is the rate of change of a function?The rate of change of a function is an indication of how fast the function's output changes per unit change in the input of the function.
Let y represent the distance of the car from the intersection, and let x represent the distance of the truck from the intersection, we get;
The distance between the car and the truck, d, can be obtained from Pythagorean Theorem as follows;
d² = y² + x²
2·d·d/dt = 2·y·dy/dt + 2·x·dx/dt
dy/dt = The speed of the car = 48 km/h = 40/3 m/s
dx/dt = The speed of the truck = 60 km/h = 50/3 m/s
y = The distance of the car from the intersection = 9 m
x = The distance of the truck from the intersection = 40 m
d² = 9² + 40² = 1681
d = √(1681) = 41
d = 41 m
Therefore;
2×41×d/dt = 2×9 × 40/3 + 2 × 40 × 50/3 = 4720/3

When this happens, we want to give each event—like rolling a two—a number that represents the likelihood of the occurrence and describes how probable it is that it will occur. Similar to this, we would like to give any event or group of outcomes—say rolling an even number—a probability that reflects how possible it is that the occurrence will take place if the experiment is carried out.Martin features a spinner with four compartments marked A, B, C, and D.

where n x, n y, and n z are the quantum numbers for the x, y, and z dimensions, respectively, and h is Planck's constant, m is the particle'smass, a, b, and c are the dimensions of the box.
The amount of various quantum number combinations that result in the same energy is the degeneracy of an energy level.
The degeneracies of the first four energy levels for a three-dimensional box with a=b=1.5c are as follows:
1 degeneracy at first energy level (n=1)
Third degeneracy at second energy level (n=2)
6 degeneracies at third energy level (n=3)
10 degeneracies at energy level four (n = 4)
Hence, This circumstance may happen if one of the RHS coefficients is 0. The objective value and solution remain the same in this situation, but there are still variables. Degeneracy describes this condition.

A rectangular picture is 7 inches by 5 inches and has a border of uniform width surrounding it. If the area of the picture and the border is 80 square inches find the width of the border
The width of the rectangle border is 3 in.
What is area of rectangle?
The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the sum of its length and breadth.
Here We know that ,
Area of the rectangle = length* width square unit.
Here area of the picture and border is 80 [tex]in^2[/tex] Then,
=> (7+w)*(5+w)=80
=> [tex]35+5w+7w+w^2=80[/tex]
=> [tex]12w+w^2=45[/tex]
=> [tex]w^2+12w-45=0[/tex]
=> [tex]w^2+15w-3w-45=0[/tex]
=> w(w+15)-3(w+15)=0
=> (w-3)(w+15)=0
=> w=3 , w=-15( negative is neglected)
Hence the width of the rectangle border is 3 in.
