It has a base perimeter of 36 inches, a slanted height of 11 inches, and is leaning at
70°. The base is a regular hexagon with a perimeter of 36 inches.
6.70%
11"
The volume of the leaning regular hexagonal prism, can be found to be 351. 89 inch ³.
How to find the volume ?A right triangle can be constructed in a regular hexagon by linking the midpoint of one side and a vertex to the center. This specially-crafted triangle comprises two legs, one of which is half the size of the primary side (acting as the hypotenuse) while the remaining leg lies parallel to the hexagon's apothem (height).
The height of the prism can be found with cosine to be:
h = slanted height x Cos (angle )
h = 11 x Cos ( 70 degrees )
h = 3. 762 inches
We can then find the volume of the leaning hexagonal prism to be:
= Area x Height
= 93. 528 x 3. 762
= 351. 89 inch ³

What is the equation for making a skateboard?
Here's an equation that outlines my "recipe" for making a skateboard:
Skateboard = Deck + Grip Tape + Trucks + Wheels + Bearings + Hardware + Assembly + Personalization
Explanation of the equation:
Deck: The wooden or composite board that serves as the main body of the skateboard. It is typically made from layers of plywood or other materials, and its dimensions (length, width, concavity, etc.) can be customized based on personal preference.
Grip Tape: A sandpaper-like material that is applied to the top of the deck to provide traction for the rider's feet. It is usually made of adhesive-backed paper or fabric and comes in various designs and colors.
Trucks: Metal T-shaped components that are mounted on the underside of the deck and serve as the axle and suspension system of the skateboard. They consist of a baseplate, hanger, kingpin, bushings, and hardware, and are responsible for allowing the board to turn and pivot.
Wheels: Typically made of urethane or other durable materials, skateboard wheels come in various sizes, shapes, and hardness levels (durometer). They are attached to the trucks and provide smooth rolling and maneuverability.
Bearings: Small, round metal or ceramic components that fit inside the wheels and allow them to spin freely on the axle. They are crucial for reducing friction and enabling the wheels to roll smoothly.
Hardware: Nuts, bolts, and screws used to attach the trucks to the deck and assemble the skateboard. They are typically made of metal and come in different sizes and lengths.
Assembly: The process of putting together all the skateboard components to create a functional skateboard. It involves attaching the trucks to the deck using the hardware, installing the wheels and bearings, and applying the grip tape.
Personalization: This refers to any additional customization or personal touches that a skateboarder may choose to add to their skateboard, such as stickers, artwork, or modifications to the deck shape or truck settings, to make it unique and suited to their individual style.

The output for an input of n is given as follows:
f(n) = -4 - 2n.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.For this problem, we have that when x increases by one, y decays by two, hence the slope m is given as follows:
m = -2.
Hence:
f(n) = -2n + b.
When n = 1, f(n) = -6, hence the intercept b is obtained as follows:
-6 = -2 + b
b = -4.

Indirect measurement, pls help, I am stuck on this question.
The building is, 246 feet tall.
Since, We know that;
Two or more triangles will always be referred to as similar if on comparing their corresponding properties, some common relations holds. Some of the relations are relations between their length of sides, relations among their internal angles etc.
To determine the height of the building, we have;
height of pole = 7 ft
total length of the building's shadow = 167 ft
the length of the shadow of the pole = 4.75 ft
Let the height of the building be represented by h. On comparison, we have;
4.75/ 167 = 7/h
4.75h = 167 x 7
= 1169
h = 1169/ 4.75
h = 246.11

What is a cosine rule?A cosine rule is a trigonometric function that can be used to determine the length of side, or measure of the internal angles of a none right angled triangle.
Cosine rule states that;
[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B
To determine the missing values of the triangle in the attached diagram, we have;
[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] -2acCos B
= 4^2 + 7^2 - 2(4*7)Cos35^o
= 16 + 49 -2(36*0.8192)
= 65 - 58.9824
= 6.0176
b = (6.0176)^1/2
= 2.4531
b = 2.45
From sine rule,
a/ Sin A = b/Sin B = c/ Sin C
a/ Sin A = b/Sin B
4/Sin A = 2.45/ Sin 35
Sin A = 4* Sin 35/ 2.45
= 0.9365
A = Sin^-1 0.9365
= 69.47
A = 69.5
So to determine the value of C, we have;
A + B + C = 180^o
69.5 + 35 + C = 180

Answer:
Step-by-step explanation:
To solve this problem, we need to use the distance formula to find the length of each side of the triangle, and then apply the Pythagorean theorem to determine whether the triangle is a right triangle.
Let's label the three vertices of the triangle as A, B, and C, and their coordinates as follows:
A = (-2, 5)
B = (3, -1)
C = (1, 3)
The length of AB is:
AB = sqrt((3 - (-2))^2 + (-1 - 5)^2) = sqrt(25 + 36) = sqrt(61)
The length of AC is:
AC = sqrt((1 - (-2))^2 + (3 - 5)^2) = sqrt(9 + 4) = sqrt(13)
The length of BC is:
BC = sqrt((1 - 3)^2 + (3 - (-1))^2) = sqrt(4 + 16) = sqrt(20) = 2sqrt(5)
Now, we need to check whether the triangle is a right triangle. We can do this by checking whether the sum of the squares of the two shorter sides (AB and AC) is equal to the square of the longest side (BC). If it is, then the triangle is a right triangle.
AB^2 + AC^2 = 61 + 13 = 74
BC^2 = (2sqrt(5))^2 = 20
Since AB^2 + AC^2 is not equal to BC^2, the triangle is not a right triangle.
Therefore, the answer is: "The triangle is not a right triangle."

In triangle ABC, a=6, b=7, and cos C=1/4 A.) Find the exact area of the triangle. B.) Find C C.) Find sin A in simplest radical form.
A.) Area = (1/2) × 7 × 6 × √(15)/4 = 21√(15)/4
B.) Angle C is 75 degrees.
C.) Sin(A) is 3√(255)/85 in simplest radical form.
What is trigonometry?Trigonometry is a branch of mathematics that examines triangle-related relationships and calculations, particularly the measurement of triangle sides and angles.
A.) We can apply the following formula to determine the triangle's area:
Area = (1/2) × b × a × sin(C)
Since we know b=7 and a=6, we have:
Area = (1/2) × 7 × 6 × sin(C)
To find sin(C), we can use the fact that cos(C) = 1/4 and the Pythagorean identity:
sin²(C) + cos²(C) = 1
sin(C) = √(1 - cos²(C)) = √(1 - 1/16) = √(15/16) = √(15)/4
B.) To find C, we can use the Law of Cosines:
c² = a² + b² - 2ab×cos(C)
c² = 6² + 7² - 2(6)(7)(1/4) = 85/2
c = √(85)/2
Now we can use the Law of Cosines again to find angle C:
cos(C) = (a² + b² - c²)/(2ab)
cos(C) = (6² + 7² - (√(85)/2)²)/(267) = 1/4
C.) To find sin(A), we can use the Law of Sines:
sin(A)/a = sin(C)/c
sin(A) = asin(C)/c = 6(√(15)/4)/(√(85)/2) = 3×√(15)/√(85) = √(255)/85

Angle or arc HGJ is measured at 275 for given figure.
What does arc of circle stands for?Arcs may be created from the circumference of a circle. It is referred to as the curved line that connects two locations on a circle's perimeter and splits it into segments. The length of an arc is inversely proportional to the angle it makes at the centre of the circle.
When the central angle rises, so does the arc's length, and vice versa. Arcs are commonly used to depict and compute measurements of circles and circular objects in geometry, trigonometry, and physics.
For given problem,
mHGJ= 360° - mJH = 360°-( mJl + mlH ) = 360°-(30°+55°)

Hailey goes to a store an buys an item that costs a dollars. She has a coupon for 35%
off, and then a 8% tax is added to the discounted price. Write an expression in terms
of a that represents the total amount that Hailey paid at the register.
Hailey goes to a store an buys an item that price of a dollars, so the expression that represents the total amount that Hailey paid at the register in terms of a is 0.702a.
The amount of discount that Hailey receives is 35% of the original price, which is 0.35a. Therefore, the discounted price she pays is a - 0.35a = 0.65a.
The amount of tax that is added to the discounted price is 8% of the discounted price, which is 0.08(0.65a) = 0.052a.
So the total amount that Hailey paid at the register is the discounted price plus the tax:
total amount = discounted price + tax
total amount = 0.65a + 0.052a
Simplifying this expression, we get:
total amount = 0.702a

James bought 16 bolts at the hardware store for a total of $6.00/ Some were 3-inch bolts that cost 36 cents each and the others were 4-inch bolts that cost 42 cents each. How many 3-inch did James buy
Let's use the variable "x" to represent the number of 3-inch bolts that James bought.
We know that he bought a total of 16 bolts, so the number of 4-inch bolts he bought would be 16 - x.
The cost of the 3-inch bolts is 36 cents each, so the total cost of the 3-inch bolts would be 0.36x dollars.
Similarly, the cost of the 4-inch bolts is 42 cents each, so the total cost of the 4-inch bolts would be 0.42(16 - x) dollars.
We know that the total cost of all the bolts was $6.00, so we can set up the following equation:
0.36x + 0.42(16 - x) = 6.00
Simplifying and solving for x, we get:
0.36x + 6.72 - 0.42x = 6.00
-0.06x = -0.72
x = 12
Therefore, James bought 12 of the 3-inch bolts.
