The total surface area of the triangular prism is 1008 square inches.

What is surface area?

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

To find the total surface area of a triangular prism, we need to find the area of each of its faces and add them up.

First, let's find the area of the triangular bases.

We need to know the base and height of the triangle.

If we don't have those measurements, we need to use the information given in the problem to find them.

Next, we need to find the area of each of the rectangular faces.

We need to know the length, width, and height of the rectangular face.

Once we have all of the areas, we add them up to find the total surface area.

Let's assume that the triangular prism has an equilateral triangle as its base with side length s.

Then, the height of the triangle is also s.

The area of an equilateral triangle with side length s and height h is given by -

A = (1/2)sh

Substituting s = h = 12 inches, we get -

A = (1/2)(12)(12) = 72 square inches

So, the area of each of the two triangular faces is 72 square inches.

To find the area of each rectangular face, we need to know its length, width, and height.

Let's assume that the rectangular faces have length s and width w.

The height of the triangular prism is given as 12 inches, which is also the height of the rectangular faces.

The area of a rectangle with length l, width w, and height h is given by -

A = 2lw + 2lh + 2wh

Substituting l = s = 12 inches, w = s/2 = 6 inches, and h = 12 inches, we get -

A = 2(12)(6) + 2(12)(12) + 2(6)(12) = 432 square inches

So, the area of each of the rectangular faces is 432 square inches.

Therefore, the total surface area of the triangular prism is -

2(72) + 2(432) = 1008 square inches.

Therefore, the total surface area value is obtained as 1008 square inches.

The radius of Deimos to one significant digit in meters is approximately 9.4 m

.

Given the ratio of the Sun-from-Mars distance to Deimos-from-Mars distance is 365,000, the distance between Mars and Deimos can be found to bedeimos distance = Sun-Mars distance / 365,000

Next, we can find the diameter of Deimos by noting that 550 of its diameters is equal to the distance it takes to transit the shadow of Mars during a lunar eclipse.

Let's call the diameter of Deimos "d", so we can

diameter = 1/550 * deimos distance

Finally, the Sun appears about 8.4 times as large as Deimos in the Martian sky. If we call the radius of Deimos "r", then the radius of the Sun is 8.4r.

Using the information given, we can set up the following equation:

deimos distance / (3,000,000 + r) = 8.4r / (3,000,000)Simplifying and solving for r,

we get:r = 9.39 m (rounded to one significant digit)

The circumference of the circle with a diameter of 40 is approximately 125.6636 units.

To calculate the circumference of a circle, we can use the formula:

Circumference = π * Diameter

Given that the diameter of the circle is 40, we can substitute this value into the formula:

Circumference = π * 40

The value of π (pi) is approximately 3.14159, so we can further simplify the equation:

Circumference ≈ 3.14159 * 40

Calculating this expression gives us:

Circumference ≈ 125.6636

Therefore, the circumference of the circle with a diameter of 40 is approximately 125.6636 units. Note that the unit of measurement is not provided in the question, so the answer is given in generic units.

The statement "the sophists were principally concerned with mathematics, and formulated the so-called Pythagorean theorem" is not entirely accurate.

While the sophists were a group of philosophers who were known for their expertise in various subjects, including mathematics, they did not formulate the Pythagorean theorem. This theorem is named after Pythagoras, a philosopher and mathematician who lived in ancient Greece.The sophists were more concerned with rhetoric and the art of persuasion.

They were skilled at using language and arguments to influence others, and they often taught these skills to others for a fee. While they may have had some knowledge of mathematics, their primary focus was not on this subject.In fact, the Pythagorean theorem is traditionally attributed to Pythagoras and his followers, who were known as the Pythagoreans.

This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This is a fundamental concept in geometry, and it has many practical applications in fields such as engineering and physics.In conclusion, while the sophists may have had some knowledge of mathematics, their primary focus was on rhetoric and persuasion. The Pythagorean theorem is traditionally attributed to Pythagoras and his followers, not the sophists.

ECH is an acute angle.

FCG is also an acute angle.

Answer:

Vertical angles

Step-by-step explanation:

Vertical angles are angles formed by two intersecting lines, which the angles are facing the opposite direction. Also the angles are on the same vertice (point).

The equation of the line passing through (9,11) and perpendicular to the line passing through (6,1) and (2,1) is x = 6

Find the slope of the line passing through (6,1) and (2,1):

The slope of a line passing through two points (x1,y1) and (x2,y2) is given by:

slope = (y2 - y1) / (x2 - x1)

Substituting the given coordinates, we get:

slope = (1 - 1) / (2 - 6) = 0

Therefore, the slope of the line passing through (6,1) and (2,1) is 0.

Find the slope of the line perpendicular to the line passing through (6,1) and (2,1):

The slope of a line perpendicular to a line with slope m is given by:

perpendicular slope = -1/m

Substituting the slope of the line passing through (6,1) and (2,1), we get:

perpendicular slope = -1/0 (which is undefined)

This means that the line perpendicular to the line passing through (6,1) and (2,1) is a vertical line passing through the point (6,1) and (2,1).

Write the equation of the line passing through (9,11) and perpendicular to the line passing through (6,1) and (2,1):

Since the line passing through (6,1) and (2,1) is a horizontal line with equation y = 1, the line perpendicular to it is a vertical line passing through the point (6,1) and (2,1). The equation of a vertical line passing through a point (a,b) is given by:

x = a

Substituting the value of x = 6 (since the vertical line passes through (6,1) and (2,1)), we get:

x = 6

The graph of the linear inequality is shown below.

What is linear inequality?

A linear inequality is one that, if the equals relation were employed in place of the inequality, would result in a linear equation. The direction of the inequality is reversed when both sides are multiplied or divided by a negative integer to solve it. The solution set refers to all possible answers to an inequality.

We are given y < -x-4

In order to sketch the graph of the inequality, we need to have two points.

So, first let's put x = 0

So, we get y = -4

Now, let's put y = 0

So, we get x = -4

Thus, we get the points as (0,-4) and (-4,0)

From the points, the graph is sketched which is shown below.

Hence, the graph of the linear inequality is obtained.

Since, there are multiple questions, so the question answered above is attached below

Answer:

A

Step-by-step explanation:

A

Answer:

If 67.5% of the 540 km road between the two cities is paved, then the length of the paved road is:

Length of paved road = 67.5% of 540 km = 0.675 x 540 km = 364.5 km

The length of the unpaved road is the remaining distance:

Length of unpaved road = 540 km - 364.5 km = 175.5 km

Let's call the speed of the car on unpaved roads "x". Then, according to the problem, the speed of the car on paved roads is "x + 25". We can use the formula:

Time = Distance / Speed

to set up two equations based on the paved and unpaved parts of the road. We know that the total time to cover the entire road is 10 hours, so we can use this to solve for the two unknown speeds:

Time on paved road + Time on unpaved road = 10 hours

Length of paved road / (x + 25 km/h) + Length of unpaved road / x km/h = 10 hours

Substituting the values we found earlier, we get:

364.5 km / (x + 25 km/h) + 175.5 km / x km/h = 10 hours

Multiplying both sides by the LCD, we get:

364.5x + 175.5(x + 25) = 10x(x + 25)

Simplifying and solving for x, we get:

540x = 10000

x = 18.52 km/h

Therefore, the speed of the car on unpaved roads is 18.52 km/h, and the speed on paved roads is x + 25 = 43.52 km/h.

The equation of the line perpendicular to line ab and passing through point c is 3y + x = 13.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

a is the point (-5,2),

b is the point (7,-2),

c is the point (-2,5),

the gradient of ab is 3.

The gradient of the line perpendicular to ab is, m = - 1 / 3

Calculate the equation of the line as shown below,

y - 5 = -1/3 [x-(-2)]

y - 5 = -1/3(x + 2)

3y - 5 × 3 = -x - 2

3y + x = -2 + 15

3y + x = 13

Therefore, the equation of the line perpendicular to line ab and passing through point c is 3y + x = 13.

The statement "Quadrilaterals A and B are both squares" does not provide enough information to determine whether A and B are scale copies of one another.

To determine if two quadrilaterals are scale copies of each other, we need to compare their corresponding sides and angles. If the corresponding sides of two quadrilaterals are proportional and their corresponding angles are congruent, then they are scale copies of each other.

In this case, since both A and B are squares, we know that all of their angles are right angles (90 degrees). However, we do not have any information about the lengths of their sides. Without knowing the lengths of the sides of A and B, we cannot determine if they are scale copies of each other.

Therefore, the statement cannot be determined as true or false based on the given information.
