The number of students present at the dinner is 17

As stated in the question, a group of students had dinner at a local restaurant.

The total bill for the dinner was $364.99 and each student paid an equal share of the bill which is $21.47. according to the question we have to find the number of students present at the dinner,

To find the number of students we have to divide the total bill by the amount paid by each student,

Let the number of students who were present at the dinner be x

Now number of students = total bill/amount paid by each student

Hence, x = $364.99 ÷ $21.47

So the value of x is 17

The minimum number of degrees needed to carry the pentagon onto itself is 72.

A polygon having 5 sides and 5 angles are called a pentagon. Two terms, Penta and Gonia, both of which denote five angles, combine to form the word "pentagon." From end to end, the sides of a pentagon come together to form a shape. Consequently, there are five sides to a pentagon. The Pentagon has five sides, as far as we know.

Any polygon's outside angles now total 360 degrees. The minimal number of degrees needed to carry the pentagon inward is therefore = 360/5 = 72° if we rotate the pentagon counterclockwise around its center.

The equation of line which describe how x and y are related is,

⇒ y = 5x + 3

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the table are (-1, -2) and (0, 3).

Now,

Since, The equation passes through the points (-1, -2) and (0, 3).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (3 - (-2)) / (0 - (-1))

m = 5 / 1

m = 5

Thus, The equation of line with slope 5 is,

⇒ y - (-2) = 5 (x - (-1))

⇒ y + 2 = 5 (x + 1)

⇒ y + 2 = 5x + 5

⇒ y = 5x + 5 - 2

⇒ y = 5x + 3

Therefore, The equation of line passes through the points (-1, -2) and

Answer:

Hello!

a) Melody's average 4 year salary = (56,000 + 60,000 + 73,000 + 75,000) / 4

= 264,000 / 4

= 66,000

So, Melody's average 4 year salary is $66,000.

Step-by-step explanation:

Melody has worked for 30 years at Fancy Pet magazine and is planning to retire at the end of the year. As per her employer's pension formula, she will receive 2.5% of her average salary over the last four (4) years of employment for every year worked.

To calculate Melody's average salary over the last four years, we first need to add up her salary from the last four years: 56,000 + 60,000 + 73,000 + 75,000 = 264,000. Then, we divide this sum by 4 to find the average: 264,000 / 4 = 66,000.

Therefore, Melody's average 4 year salary is $66,000. With this information, we can calculate the amount of pension she will receive based on her years of employment and the pension formula offered by her employer.

Answer:

$1,000 to the nearest dollar

Step-by-step explanation:

We can use the formula for compound interest to calculate the amount that Khalil would need to invest:

A = P * (1 + r/n)^(nt)

where A is the final amount, P is the initial amount (the amount invested), r is the interest rate as a decimal (6.6% = 0.066), n is the number of times compounded in a year (daily = 365), t is the number of years, and ^ is the exponent operator.

We want to find P, so we can rearrange the formula:

P = A / (1 + r/n)^(nt)

Plugging in the values:

P = $1,470 / (1 + 0.066/365)^(365 * 9)

Calculating this expression to the nearest dollar, we get P = $1,000.

So, Khalil would need to invest $1,000, to the nearest dollar, in order for the value of the account to reach $1,470 in 9 years

The distance between Woozy Wheel and the Roller Rail is 13 units.

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

Distance between two points (x, y) and (x', y') is,

D = √[(x' - x)² + (y' - y)²]

Coordinates of Woozy Wheel = (-14, 1)

Coordinates of Roller Rail = (-2, -4)

Distance = √ [(-2 - -14)² + (-4 - 1)²]

               = √ [(12)² + (-5)²]

The distance between the Woozy Wheel and the Roller Rail is 13 units.

The correct option is D.

Distance between two points with coordinates (x₁ , y₁)  and (x₂ , y₂). is given by

D = √[(x₁ - x₂)² + (y₁ - y₂)²]

This formula is derived from the Pythagoras Theorem, as the points form a right triangle in plane, with the hypotenuse representing the distance between them.

The coordinates of the Woozy Wheel and the Roller Rail are:

Woozy Wheel: (-14, 1).

Roller Rail: (-2, -4).

Hence the distance between these two points is given as follows:

D = √[(-14 - -2)² + (1 - -4)²]

D = √(-12² + 5²)

D = √(144 + 25)

D = √169

D = 13

The number of edges that the prism has is

When a plane intersects a prism, the shape formed is known as the cross section. The cross section of the prism will have the same form as the base if it is divided by a plane that runs horizontally and parallel to the base.

A prism is a 3-dimensional object with two congruent and parallel bases (which are polyggonal) connected by rectangular lateral faces. The number of edges of a prism is equal to the sum of the number of edges of the two bases and the number of lateral faces.

Each base of the prism has n edges, so the two bases together have 2n edges. The number of lateral faces of the prism is equal to the number of edges of one of its bases, so there are n lateral faces. Each lateral face has 4 edges, so the total number of edges of the lateral faces is 4n.

Therefore, the total number of edges of the prism is equal to the sum of the number of edges of the two bases (2n) and the number of lateral faces (4n), which is 2n + 4n = 6n.

In conclusion, the cross section of a prism is an n-sided polygon and the prism has n + 2 edges.

Approximately 68% of the data to fall between 50 - 10 = 40 and 50 + 10 = 60

Approximately 95% of the data to fall between 50 - 2 * 10 = 30 and 50 + 2 * 10 = 70

There can be a maximum of 1183 bags, each containing 5 red cubes and 5 blue cubes.

Let x be the number of red cubes in each bag and y be the number of blue cubes in each bag. Then, the number of red cubes in all bags is 5915/x, and the number of blue cubes in all bags is 1715/y.

Since the number of cubes in each bag is the same and there will not be any cubes left over, we must have 5915/x = 1715/y = z, where z is the number of bags.

To find the greatest value of z, we need to find the greatest common factor (GCF) of 5915 and 1715. We can use the Euclidean algorithm:

5915 = 1715 × 3 + 720

1715 = 720 × 2 + 275

720 = 275 × 2 + 170

275 = 170 × 1 + 105

170 = 105 × 1 + 65

105 = 65 × 1 + 40

65 = 40 × 1 + 25

40 = 25 × 1 + 15

25 = 15 × 1 + 10

15 = 10 × 1 + 5

10 = 5 × 2 + 0

The GCF of 5915 and 1715 is 5, so each bag will contain 5 red cubes and 5 blue cubes. The number of bags is z = 5915/5 = 1183.

The other angles of the triangle are x = 28° and y = 62°. The result is obtained by using the trigonometric ratios.

Where opp is opposite, hyp is hypotenuse, and adj is adjacent.

In Pythagorean Theorem, the triangle is a right triangle. It means that one angle is 90° and two others added equal to 90°. The two angles can be found by the trigonometric ratios.

A triangle with side lengths 8, 15, and 17 is a right triangle by the converse of the Pythagorean Theorem.

Find the measures of the other 2 angles! (x and y)

Let θ = x.

sin x = opp/hyp

sin x = 8/17

x = 28°

If x = 28, then y will be

y = 180 - (90 + 28)

y = 180 - 118
