The interior angles formed by the sides of a hexagon have measures that sum to 720°.
What is the measure of angle F?
Enter your answer in the box.
m∠F=
Answers
Answer:
Step-by-step explanation:
(x-60)+(x-20)+(x-40)+130+120+110=720
3X -120 + 360=720
3x +240= 720
3x= 720-240
3x=480
x= 480/3 = 160
x=160
angle F = (x-20)
angle F = 160-20=140
angle F = 140

State whether the following statement is true and explain why or why not: A trinomial is always a higher degree than a monomial. Give an example proving your answer is correct.
Grading: 2 points: Correct Answer; 2 points: Explanation; 1 point: Example
Answers
The given statement that a trinomial is always a higher degree than a monomial is false because greater number of terms does not means higher degree.
A monomial is an algebraic expression with only one term. Or we can say that the representation of a single concept is a monomial.
An example of an unary expression is: 12
A trinomial is an algebraic expression containing three terms. An example of a ternary is: x + y + 7
A trinomial is always of higher degree than a monomial is false statement .
A counterexample can be used to explain why this is wrong. Suppose we have a monomial, 8⁵ and then a trinomial x² + 2x + 3 . This is just a random example. This monomial has a higher degree because 5 is greater than 2. So basically it doesn't matter what the monomial is, if the degree is higher it is just a term than the maximum degree of the trinomial. Just because this has three terms does not mean that the highest degree term is greater than his one term in the monomial.

Find the area of the composite figure. I got 78 but my teacher said that it is incorrect. WILL MARK BRAINLIEST! Thanks!
Answers
Answer:
44
Step-by-step explanation:
Essentially there are 3 triangles
The top left has a base of 5 and a height of 4
Its area is 1/2 x b x h = 1/2 x 5 x 4 = 10
Then there are two triangles with the same base of 2.5 + 6 = 8.5 and same height of 4 feet. So each of the triangles has the same area as the other.
Total area of both triangles = 2 (1/2 x b x h) = bh = 8.5 x 4 = 34
Total area = 10 + 34 = 44
Answer:
44 ft²
Step-by-step explanation:
Here's how I divided the parts of the composite figure:
1. There is a triangle at the left with the vertex pointing down and base above. The base is 5 ft. The height is 4 ft.
2. There are 4 triangles left. I divided them into two triangles like this:
An upper triangle which has a base of 2.5 ft + 6 ft, and a height of 4 ft with a horizontal base on the bottom and a vertex on the upper side.
A lower triangle that is a mirror image of the triangle just above. The dimensions are the same.
Triangle on upper left:
base = 5 ft
height = 4 ft
Triangles at right (2 triangles with the same dimensions)
base = 2.5 ft + 6 ft = 8.5 ft
height = 4 ft
area of triangle = base × height / 2
Total Area = (5 ft)(4 ft)/2 + 2 × (8.5 ft)(4 ft)/2
Total Area = 10 ft² + 34 ft²
Total Area = 44 ft²

How do functions work?The term "function" refers to the relationship between a collection of inputs and outputs with one each. Simply described, a function is an association of inputs where each input is coupled with exactly one output. Every function has an associated domain, codomain, or range. The most common way to represent a function is as f(x), where x represents the input.
To calculate the average rate of change, use the slope formula:
y2−y1/x2−x1=m
f(4)−f(2)/4−2=m
Finding the values of f(4) and f(2) will help us to simplify this.
f(4)=2(3)4=2(81)=162
f(2)=2(3)2=2(9)=18
m=162−18/2
m=144/2
m=72

Given, a rectangular vegetable patch.
The fencing for the east and west sides costs $4 per foot, and the fencing for the north and south sides costs only $2 per foot.
We have a budget of $96 for the project.
Let the length of the rectangle be, l
and breadth of the rectangle be, b
according to the ques,
4l + 8b = 96
l + 2b = 24
l = 24 - 2b
Now, area of the rectangle be,
Area = length×breadth
Area = l×b
A = (24 - 2b)b
A = 24b - 2b²
On differentiating both sides, we get
A' = 24 - 4b
b = 6
l = 24 - 12 = 12
So, the dimensions of the vegetable patch with the largest area we can enclose are
length = 12 feet and breadth = 6 feet.
Hence, The dimensions of the vegetable patch with the largest area we can enclose are
length = 12 feet and breadth = 6 feet.

What is a triangle?
The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.
As per the given information given in the question,
p= 16.2
q = 35.0 m and,
m ∠R = 75°
Find x by cosine rule,
cos 75° = (16.2² + 35² - x²)/(2 × 16.5 × 35)
x = 34.5 m
The value of r is 34.5 mm then the third side of the triangle pqr will be,
Use heron's formula,
s = (16.2 + 35 + 34.5)/2
s = 42.85

At 30 ft the wire is anchored to the ground (in ft, from the shorter pole) to minimize the amount of wire needed.
What is the quadratic equation?
Any equation in algebra that can be written in standard form as where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation. In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.
Let x (ft) be the distance from the base of the left pole to the anchor point. Since 2 poles has a distance of 45 ft, the distance from the anchor point to the right pole is 45 - x
The wire length from the top of the left pole to the anchor point is
[tex]L^{2} _l = 30^{2} + x^{2}[/tex]
= x² + 900
Similarly for the 2nd part of the wire
[tex]L^{2} _r = 15^{2} + (45-x)^{2}[/tex]
= 256 + 2025 - 45x + x²
= x² + 2281 - 45x
We want to minimize the length of the wires, or [tex]L_l + L_r[/tex]
√x² + 900 + √ x² + 2281 - 45x
we can take the first derivative of this and set it to 0
[tex]\frac{x}{\sqrt{ x^2 + 900} } + \frac{45 - x}{\sqrt{x^2 + 2281 - 45x} } = 0[/tex]
x = 30
Hence, at 30 ft the wire is anchored to the ground (in ft, from the shorter pole) to minimize the amount of wire needed.

Using the compound interest method, we can calculate that Danni will have $6,194.09 in her account after 4 years.
What is compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
Compound interest works by periodically adding collected interest to your main, which is the sum you first deposited into the savings account so that interest can then be earned on both.
In essence, your interest begins to generate interest of its own.
Compound interest formula: [tex]A=P\left(1+\frac{r}{100}\right)^{n t}[/tex]
Now, calculate the amount Danni will have after 4 years:
[tex]A=P\left(1+\frac{r}{100}\right)^{n t}[/tex]

A = 5700(1.0210⁴

Answers
29.78% of customers will most likely probability be waiting between 4 and 9 minutes.
Explain the term z-score of the normal distribution?An observation's Z score indicates however many standard deviations it deviates from the mean. The standard normal distribution's mean is zero. Positive Z scores are those above the mean, while negative Z scores are those below the mean.The formula for the z score is-
z = (x - μ)/σ
In which,
μ = mean of 10. 3 minutes
σ = standard deviation of 2. 7 minutes.
z score for the x = 4 minutes.
z = (4 - 10.3)/2.7
z = -2.33
z score for the x = 9 minutes.
z = (9 - 10.3)/2.7
z = -0.48
Thus,
Probability that the customer will have to wait between 4 and 9 minutes.
P(4 < x < 9) = P(-0.48 < z < -2.33)
Use z score table-
P(4 < x < 9) = 0.3085 - 0.0107
P(4 < x < 9) = 0.2978
P(4 < x < 9) = 29.78%
Thus, 29.78% of customers will most likely be waiting between 4 and 9 minutes.
