Answer:∠A = 9
Step-by-step explanation:In a Parallelogram opposite angles are always equal thus, 14x - 4 = 15x - 13.
Start by isolating the variable on one side of the equation. You can do this by subtracting 14x from both sides:
14x - 4 - 14x = 15x - 13 - 14x
Simplifying the left side gives:
-4 = x - 13
Now, isolate x by adding 13 to both sides:
-4 + 13 = x - 13 + 13
Simplifying the left side gives:
9 = x
Therefore, the solution to the equation 14x - 4 = 15x - 13 is x = 9

The length of the corresponding side of the larger polygon is 5/4.
What is polygon?
A polygon is a two-dimensional shape that is formed by connecting a sequence of straight lines (called sides or edges) end-to-end to form a closed loop. The term "poly" means "many," and "gon" means "angle," so a polygon literally means "many angles."
Polygons can have any number of sides, from three (a triangle) to infinity. The most common polygons are the quadrilateral (four sides), pentagon (five sides), hexagon (six sides), heptagon (seven sides), octagon (eight sides), nonagon (nine sides), and decagon (ten sides).
Let's assume that the smaller polygon has n sides and the larger polygon has m sides. Since the polygons are similar, their corresponding sides are proportional. Therefore, we can set up the following proportion:
n/m = 4/x
where x is the length of the corresponding side of the larger polygon.
We also know that the perimeter of the smaller polygon is 20, so each of its sides has length 20/n. Similarly, the perimeter of the larger polygon is 28, so each of its sides has length 28/m.
Since the polygons are similar, their corresponding sides are proportional, so we can set up another proportion:
(20/n) / (28/m) = 4/x
Simplifying this expression, we get:
20m = 28nx
Dividing both sides by 4, we get:
5m = 7nx
Substituting n/m = 4/x, we get:
5m = 28x
Solving for x, we get:
x = (5m)/28
Now, we need to find the value of m. The perimeter of the smaller polygon is 20, so the sum of its sides is 20. Since each side has length 20/n, we can write:
20 = (20/n)*n
Simplifying, we get:
n = 4
The perimeter of the larger polygon is 28, so the sum of its sides is 28. Since each side has length 28/m, we can write:
28 = (28/m)*m
Simplifying, we get:
m = 7
Now, we can substitute the value of m into the expression for x that we derived earlier:
x = (5m)/28 = (5*7)/28 = 5/4
Therefore, the length of the corresponding side of the larger polygon is 5/4.

Simplify the expression \( \sqrt{y^{2}-81} \) as much as possible after substituting \( 9 \sec x \) for \( y \).
The expression√{y²-81} can be simplifies to trigonometry as 9|tanx|.
If an algebraic expression has no like terms and no parenthesis, it is said to be in its simplest form. Use the Distributive Property to add or subtract the coefficients to combine like terms with variables. You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.
We start by substituting 9 sec x for y:
√{y²-81} = √{(9 sec x)²-81}
= √{81(sec²x) - 81}
= √{81(sec²x-1)}
= 9√{sec²x-1}
Using the trigonometric identity sec²x - 1 = tan²x, we can simplify further:
9√{sec²x-1} = 9√{tan²x}
= 9|tanx|
Therefore, the simplified expression is 9|tanx|.

The graph of f (x)=√x is transformed to create the
graph of g (x)= -2√x+6. Which of these describes a
transformation used to create the graph of g?
The transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.
The "-2" in the equation of g(x) reflects a vertical stretch by a factor of 2, which causes the graph to become narrower and steeper than f(x).
The "+6" in the equation of g(x) reflects a vertical shift upward by 6 units, which moves the entire graph of g(x) upward by 6 units.
Therefore, the transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.
A brick of mass 6 kg hangs from the end of a spring. When the brick is at rest, the spring is stretched by 5 cm. The spring is then stretched an additional 3 cm and released. Assume there is no air resistance. Note that the acceleration due to gravity, g, is g = 980 cm/s^2.
Set up a differential equation with initial conditions describing the motion and solve it for the displacement s(t) of the mass from its equilibrium position (with the spring stretched 5 cm).
The differential equation with initial conditions describing the motion is F = -k * (s(t) + 5) - 6g and the displacement of the mass from its equilibrium position as a function of time s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)
The differential equation for the motion of the mass is given by Newton's Second Law, F = ma:
F = -k * (s(t) + 5) - 6g
where k is the spring constant, s(t) is the displacement from the equilibrium position, and g is the acceleration due to gravity. The initial conditions are s(0) = 3 and s'(0) = 0, since the spring is initially stretched an additional 3 cm and released from rest.
We can rearrange the equation to get:
s''(t) + (k/6) * s(t) = -5k/6 - g
This is a second-order linear homogeneous differential equation with constant coefficients. The general solution is:
s(t) = C1 * e^(r1*t) + C2 * e^(r2*t)
where r1 and r2 are the roots of the characteristic equation:
r^2 + (k/6) * r = -5k/6 - g
Using the quadratic formula, we get:
r1,2 = -(k/12) ± √((k/12)^2 + 5k/6 + g)
We can find the values of C1 and C2 by applying the initial conditions:
s(0) = C1 + C2 = 3
s'(0) = C1 * r1 + C2 * r2 = 0
Solving for C1 and C2, we get:
C1 = (3 * r2) / (r2 - r1)
C2 = (3 * r1) / (r1 - r2)
Substituting back into the general solution, we get:
s(t) = (3 * r2 * e^(r1*t)) / (r2 - r1) + (3 * r1 * e^(r2*t)) / (r1 - r2)
This is the displacement of the mass from its equilibrium position as a function of time.

A popcorn container is in the shape of a square pyramid the container meausers 9 inches high and each side measures 6 inches how many cubic inches does the popcorn container hold?
NEED HELP SO LOST AND CONFUSED PLS HELPP IM NOT A VERY SMART PERSON SO HELPPPP IM LOSIN ME MIND
The popcorn container can hold 432 cubic inches of popcorn.First, we need to find the volume of the popcorn container. The formula for the volume of a square pyramid is:
Volume = (1/3) * base area * height
To find the base area, we need to first find the area of one of the square sides. Since each side measures 6 inches, the area of one square side is:
Area = side length^2 = 6^2 = 36 square inches
Since the popcorn container is a square pyramid, it has four identical square sides, so the total base area is:
Base area = 4 * 36 square inches = 144 square inches
Now we can plug in the values for the base area and height into the formula for volume:
Volume = (1/3) * 144 square inches * 9 inches
Volume = 432 cubic inches
So the popcorn container can hold 432 cubic inches of popcorn.

the sheet is a series of arcs of radius 10cm,each arc subtending 120° at it's centre. if there are 14 such arcs in one sheet, how wide would the sheet be if flattened out
The sheet would be approximately 93.13 cm wide if flattened out.
Describe Arc?The length of an arc is determined by the degree measure of the central angle that subtends the arc. For example, if a circle has a radius of 5 units and an arc has a central angle of 90 degrees, the length of the arc can be found using the formula:
arc length = (central angle / 360) x 2πr
where r is the radius of the circle. In this case, the length of the arc would be:
arc length = (90/360) x 2π(5) = 1.25π units
The length of each arc can be found using the formula:
length = (angle / 360) x 2πr
where angle is the central angle of the arc in degrees, r is the radius of the arc, and π is pi (approximately equal to 3.14).
In this case, the radius is 10 cm and the central angle is 120 degrees, so the length of each arc is:
length = (120/360) x 2π(10) = (1/3) x 20π = (20/3)π cm
There are 14 such arcs in one sheet, so the total length of the sheet when flattened out is:
total length = 14 x (20/3)π = (280/3)π cm
This is approximately equal to 93.13 cm if we use the approximation π ≈ 3.14.
Therefore, the sheet would be approximately 93.13 cm wide if flattened out.

Work out the area of the rectangle using a calculator and giving your anwser in as a mixed number
The area of the rectangle is 31/3 square centimeters or 10 1/3 square centimeters as a mixed number.
To find the area of the rectangle, we need to multiply its length by its width.
First, we need to convert the mixed numbers to improper fractions:
Length = 5 1/6 cm = (6 × 5 + 1)/6 = 31/6 cm
Width = 2 2/7 cm = (7 × 2 + 2)/7 = 16/7 cm
Now, we can multiply the two fractions to get the area of the rectangle:
Area = length × width
= (31/6 cm) × (16/7 cm)
= (31 × 16) / (6 × 7) cm²
= 496/42 cm²
= 248/21 cm²
We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor (GCF), which is 8:
248/21 cm² = (8 × 31)/ (8 × 3) cm²
= 31/3 cm²

So, x = 1 is the correct answer.
I think of a number, treble it and take 6 from my answer. If the result is 18, find the number. My teacher says its 4 I say its eight whats the answer?
Answer: Let's work through the problem step by step:
"Treble it": If we call the unknown number "x", then "trebling" it means multiplying it by 3, so we have 3x.
"Take 6 from my answer": We subtract 6 from 3x, giving us 3x - 6.
"If the result is 18": We set 3x - 6 equal to 18 and solve for x.
So, we have:
3x - 6 = 18
Adding 6 to both sides:
3x = 24
Dividing both sides by 3:
x = 8
Therefore, the answer is 8.

After how many years will the battery life of a cell phone be 2 hours? Rounds to the nearest tenth if necessary
To round to the nearest tenth, we can say that a cell phone's battery life is typically 2 hours after two years.
Generally speaking, the battery life of a cell phone will depend on the type of phone and usage habits. Most cell phones will last about 18-24 months before needing to be replaced.
The battery life of a cell phone is determined by a variety of factors, including battery capacity, phone usage habits, and battery age. We can, however, make certain assumptions and calculate how long it would take for a common mobile phone battery to decline to 2 hours of battery life.
Considering that a typical lithium-ion battery, which is often used in mobile phones, has a capacity of approximately 3,000 mAh when new and that its capacity drops by roughly 20% after 2-3 years of usage, we may estimate that the battery capacity would be around 2,400 mAh after 2-3 years.

Now, let's look at the given information. In 2010, the percentage of Hispanic or Latino people in Oregon was 11.7%. This means that out of every 100 people in Oregon, approximately 12 were Hispanic or Latino.
The political party conducted a survey of 853 adults in Oregon and found that 113 of them were Hispanic or Latino. To determine if the percentage of Hispanic or Latino people in Oregon has changed since 2010, we need to compare the survey results to the 2010 percentage.
To do this, we can calculate the percentage of Hispanic or Latino people in the survey by dividing the number of Hispanic or Latino people in the survey (113) by the total number of people surveyed (853), and then multiplying by 100. This gives us a percentage of approximately 13.2%.
Using this formula, we can estimate the margin of error for this survey to be approximately +/- 2.8%.
This means that the true percentage of Hispanic or Latino people in Oregon could be as low as 10.4% or as high as 15.6%, based on the survey results.
Since the margin of error includes the 2010 percentage of 11.7%, we cannot conclude that the Hispanic proportion of the population has definitively changed based on this survey alone.

(Open Ended) Describe a general method for adding a decimal with two decimal places to a decimal with three decimal places. Give an example.
How would I answer this?
Answer:
I think you could just add a zero onto the end of the two digit decimal, assuming it's not a decimal that continuously repeats, but is just like 2.25 or something like that. So to add 3.184 to 2.25, you would ads a 0 to the 2.25, making it 2.250.
