The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.

We have,

Determining the 99th digit of pi requires an understanding of the properties of pi and how it is calculated.

Pi is an irrational number, which means it has an infinite number of non-repeating decimal digits.

Since pi has an infinite number of digits, it is not possible to directly state the 99th digit without extensive computation.

However, various methods and algorithms have been developed to approximate the value of pi to a specific number of decimal places.

The 99th digit of pi has not been explicitly determined.

Thus,

The approximation of pi to 99 decimal places is 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679.

Maxwell takes time of 60 minutes to pack 8 boxes which is determined by the given rate of proportion.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

We have been given that Maxwell takes 45 minutes to pack 6 boxes.

Let Maxwell takes time of x minutes to pack 8 boxes.

According to the given question, we can write a proportion as

45 minutes : 6 boxes = x minutes : 8 boxes

⇒ 45/ 6 = x / 8

⇒ 7.5 = x / 8

Apply the cross-multiplication operation,

⇒ x = 8 × 7.5

⇒ x = 60

Therefore, Maxwell takes time of 60 minutes to pack 8 boxes.

As a result, $17.55 should be chosen as the selling price to sell 480,000 units for a profit of $1,500,000.

We must add the desired net profit of $1,500,000 to the total cost of producing the 480,000 units to determine the selling price.

You can determine the overall cost as follows:

Total cost equals fixed costs plus. (Variable costs per unit x Number of units)

Total expense equals $984,000 plus ($14.50 x 480,000)

Cost in total is $7,224,000.

To reach a net profit of $1,500,000, we must add the following sum to the whole expense:

Selling price is calculated as Total Cost + Desired Net Profit / Units Sold.

($7,224,000 + $1,500,000) / 480,000 = selling price

Price to Sell: $17.55

To determine whether a triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's denote the three sides of the given triangle as a = 23, b = 30, and c = 19. We can check if these side lengths satisfy the Pythagorean theorem as follows:

c^2 = a^2 + b^2

19^2 = 23^2 + 30^2

361 = 529 + 900

Since 361 is not equal to 529 + 900, we can see that the given triangle is not a right triangle.

Answer:

24°

Step-by-step explanation:

For an n-sided regular polygon, the sum of internal angles = (n-2)×180°

Since all internal angles are equal, the internal angle can is given as:

Here, it is given that the polygon has 15 sides.

So n = 15

So each internal angle is 156°.

Internal and external angles are always supplementary. So the sum of the internal and external angles is 180°.

So external angle = 180° - 156° = 24°.

The measure of each external angle is 24°.

A tessellation is a pattern made by repeating geometric shapes without any gaps or overlaps. These shapes, called tiles or polygons, fit together perfectly to cover a plane or a surface. Tessellations can be found in various forms of art, architecture, and design. They are used to create visually appealing patterns and decorations, as well as to explore mathematical concepts.

Tessellations are utilized in various practical applications, such as tiling floors, walls, and pavements, designing mosaics and quilts, and creating computer graphics and textile patterns. They are also studied in mathematics to understand concepts like symmetry, geometry, and transformations.

For polygons to tessellate, certain conditions must be met at their vertices. At each vertex, the angles formed by the polygons must add up to a whole number of degrees, typically 360 degrees. In other words, the sum of the interior angles of each polygon meeting at a vertex must be a multiple of 360 degrees.

This ensures that the polygons can fit together seamlessly without leaving any gaps or overlaps. Examples of polygons that tessellate include equilateral triangles, squares, and hexagons, as their angles add up to 360 degrees at each vertex.

A circle with center (-15,12) and a circumference of 8π, the standard equation of the circle is (x + 15)² + (y - 12)² = 16.

A standard equation is a mathematical expression that describes a relationship between two or more variables. It is a specific form of an equation that is commonly used in mathematics, science, and engineering.

In general, a standard equation has the following form:

Ax + By + C = 0

where A, B, and C are constants, and x and y are variables. This equation is called the standard form of a linear equation in two variables.

The standard equation can also be written in other forms, such as slope-intercept form, point-slope form, and general form. Each form of the equation provides different information about the relationship between the variables.

The standard equation of a circle with center (h, k) and radius r is given by:

(x - h)² + (y - k)² = r²

We know that the center of the circle is (-15, 12) and the circumference is 8π. We can use the formula for the circumference of a circle to find the radius:

C = 2πr

8π = 2πr

r = 4

Substituting these values in the standard equation, we get:

(x - (-15))² + (y - 12)² = 4²

(x + 15)² + (y - 12)² = 16

Therefore, the standard equation of the circle is (x + 15)² + (y - 12)² = 16.

Answer: 803.84cm3

Step-by-step explanation:
The formula for finding the volume of a cylinder is πr2h.
In other words, the area of the top face's circle times the height.

To find the circle's area, we first find the radius of the circle. Since the diameter is 8cm, we divide by 2 to get the radius, which is 4cm.

4cm squared is 4cm x 4cm, which is 16cm. 16cm times 3.14 is 50.24cm squared.

Now, we have the area of the circle. 50.24cm squared!

The height is 16cm, so to find the cylinder, we times the area of the circle by the height of the cylinder! So,

16cm x 50.24cm squared = 803.84cm cubed.

The volume of the can of soup is 803.84cm cubed.

Sam drove approximately 246 miles.

Let's start by subtracting the base fee from the total amount Sam paid to find the additional fee he incurred for the miles driven:

213.33 - 18.99 = 194.34

We know that the additional fee is 79 cents per mile, so we can set up an equation to find the number of miles Sam drove:

194.34 = 0.79x

where x is the number of miles driven.

To solve for x, we can divide both sides of the equation by 0.79:

x = 194.34 / 0.79 ≈ 246

Therefore, Sam drove approximately 246 miles.
