The rule for determining the cost based on the number of tickets is Cost = 30 × Tickets. Using this rule, the cost for 10 tickets is calculated to be 300 dollars.

Explanation:

The question requires us to determine a rule for the output based on the given input of tickets and then use this rule to find the cost for 10 tickets. By examining the input and output values provided, we see a consistent pattern: the cost increases by 30 dollars with each additional ticket. Given this pattern, the rule can be formulated as an algebraic expression: Cost = 30 × Tickets.

Applying this rule to an input of x tickets, the expression becomes Cost = 30 × x. To find the cost for 10 tickets, we replace x with 10: Cost = 30 × 10 = 300 dollars.

The given angles 76.2°, 81.7°, and 22.1° can make a triangle, as the sum of these angles is exactly 180°, aligning with the geometric rule that the sum of the interior angles of a triangle must be 180°.

To determine whether the given angles can make a triangle, the law in geometry states that the sum of the measures of the interior angles in a triangle must add up to 180 degrees. To see if the angles 76.2°, 81.7°, and 22.1° can make a triangle, we add them up. The sum is 76.2 + 81.7 + 22.1 = 180 degrees. Thus, yes, these three angles can form a triangle because their sum is exactly 180°.

9+9=18

194 children, 92 students, and 97 adults attended

Step-by-step explanation:

The given is:

We need to find how many children,

students, and adults attended

Assume that x represents the number of children, y represents the number of students, and z represents the number of adults

∵ There were x children, y students and z adult attended

∵ The movie theater has a seating capacity of 383

∴ x + y + z = 383 ⇒ (1)

∵ The theater charges $5 for children, $7 for students, and

   $12 for adults

∵ The total ticket sales was $2778

∴ 5x + 7y + 12z = 2778 ⇒ (2)

∵ There are half as many adults as there are children

- Half means 0.5

∴ z = 0.5x ⇒ (3)

Substitute equation (3) in equations (1) and (2)

∵ x + y + 0.5x = 383

- Add like terms

∴ 1.5x + y = 383 ⇒ (4)

∵ 5x + 7y + 12(0.5x) = 2778

∴ 5x + 7y + 6x = 2778

- Add like terms

∴ 11x + 7y = 2778 ⇒ (5)

Let us solve equations (4) and (5) to find x and y

Multiply equation (4) by -7 to eliminate y

∴ -10.5x - 7y = -2681 ⇒ (6)

- Add equations (5) and (6)

∴ 0.5x = 97

- Divide both sides by 0.5

∴ x = 194

Substitute the value of x in equations (4) and (3) to find y and z

∵ 1.5(194) + y = 383

∴ 291 + y = 383

- Subtract 291 from both sides

∴ y = 92

∵ z = 0.5 (194)

∴ z = 97

Answer:

Tommy and Manuel are 16 ft apart

Step-by-step explanation:

The locations of all three players are shown in the image below

They form a right triangle where the hypotenuse is 20 ft, and one of the legs is 12 ft. We must find the other leg.

We must use Pythagoras's theorem. Being a and b the legs of a right triangle and c its hypotenuse, then

[tex]c^2=a^2+b^2[/tex]

Knowing c and one of the legs, say b:

[tex]a^2=c^2-b^2[/tex]

Using the values c=20, b=12 we find

[tex]a^2=20^2-12^2=400-144=256[/tex]

[tex]a=\sqrt{256}=16[/tex]

So, Tommy and Manuel are 16 ft apart

Answer:

The apothem is also the radius of the incircle of the polygon. For a polygon of n sides, there are n possible apothems, all the same length of course. The word apothem can refer to the line itself, or the length of that line. So you can correctly say 'draw the apothem' and 'the apothem is 4cm'.

Final answer:

To find the apothem in geometry, one must utilize trigonometry, knowing the polygon's side length. In astronomy, calculating distances such as the semi-major axis involves understanding celestial mechanics and requires knowing the aphelion and perihelion distances. The problem content combines concepts from geometry and astronomy to discuss angles and distances.

Explanation:

Calculating the Measure of the Apothem

When attempting to find the measure of the apothem of a geometric figure, you're essentially looking for a segment that connects the center of the figure to the midpoint of one of its sides and is perpendicular to that side. This is especially common in regular polygons. However, this particular problem seems to blend geometry and astronomy, discussing the apparent width of the Moon and comparing it using similar triangles.

To calculate the apothem in a regular polygon, you can use trigonometry if you know the length of one of the sides and the number of sides. On the other hand, if the setting involves celestial bodies like the moon and planets, determining an apothem-like distance would involve understanding the object's orbit, size, and distance from the observer.

To compute the semi-major axis of an elliptical orbit, like that of a planet around a sun, you would use the sum of the aphelion and perihelion, divided by two. For instance, if we know the perihelion (rp) and aphelion (ra), we calculate the semi-major axis (a) as (ra + rp)/2.

Remember, an angle is used in astronomy to measure the apparent separation between celestial objects as seen from Earth. Astronomers use degrees to describe these angles, and knowing the angular size can help in estimating distances in space.

To find the aphelion or semi-major axis of an orbit, certain equations are used that involve these distances. Such calculations are essential for understanding celestial mechanics and the movement of objects in our solar system.

Answer:

perimeter =3200cm

Step-by-step explanation:

l=12m=1200cm

w=400cm

perimeter=2(w+l)

=2(1200+400)

=2(1600)

=3200cm

The perimeter of a rectangle in cm that has a length of 12 meters and a width of 400cm is 3200 cm

perimeter of a rectangle = 2(l + w)

where

l = length

w = width

Therefore,

let's convert meters to centimetres

1m = 100 cm

12m = ?

cross multiply

length = 1200 cm

width = 400 cm

perimeter of the rectangle = 2(1200 + 400)

perimeter of the rectangle = 2(1600)

perimeter of the rectangle = 3200 cm

Answer:

c = 10 , d = 26

Step-by-step explanation:

In the rectangular prism, we know the fact that the three faces are mutually perpendicular to each other. So, it has a rectangular base.

Given, the length and breadth of the rectangle are 8 and 6 units, and the diagonal is c.

Since it is a rectangle, length , breadth and diagonal from a right angled triangle.

So we have, c² = 6² + 8² = 36 + 64 = 100

⇒           c = 10 units

For the side face:

Length = 24 units.

As we can see, the edge of the side face is perpendicular to the base of the prism. Which means, any line on the base of the prism is perpendicular to the 24units side edge.

So we can say that , the diagonal of the rectangular base of the prism (c) is perpendicular to the 24 units side face edge.

Hence, 24 , d and c (which is 10units) form a right angled triangle

From pythagoras theorem:

   d² = 24² + 10² = 576 + 100 = 676

⇒ d = 26 units

Answer:

$40

Step-by-step explanation:

Let the total bill be "x"

Now,

Anna paid 40% (40/100 = 0.4) of the bill, that means

Cassie paid 100 - 40 = 60% of the bill, that is 60/100 = 0.6

Anna paid 0.4x  &  Cassie paid 0.6x

Cassie's amount is 8 dollar more, so we can write:

0.6x - 8 = 0.4x

Now, we solve for x:

0.6x - 0.4x = 8

0.2x = 8

x = 8/0.2

x = 40

THe total bill is $40

Answer:

x = 3.576 and x = - 3.076

Step-by-step explanation:

Two functions are given to be, g(x) = 2x² + 3x + 10 and k(x) = 2x + 16.

Now, we have to solve the equation g(x) = 2k(x)  

⇒ 2x² + 3x + 10 = 4x + 32

⇒2x² - x - 22 = 0

The expression in the left hand side can not be factorized and therefore we have to use Sridhar Acharya formula which gives the solutions of the equation in the form ax² + bx + c = 0 are given by  

[tex]x = \frac{-b + \sqrt{b^{2} - 4ac} }{2a}[/tex] and [tex]x = \frac{-b - \sqrt{b^{2} - 4ac} }{2a}[/tex]

Therefore, the solutions of the given equation are  

[tex]x = \frac{-(- 1) + \sqrt{(- 1)^{2} - 4 (2)(-22)}  }{2(2)} = 3.576[/tex]

and [tex]x = \frac{-(- 1) - \sqrt{(- 1)^{2} - 4 (2)(-22)}  }{2(2)} = -3.076[/tex] (Answer)

Final answer:

To solve the equation g(x) = k(x) for x, we simplify it to 2x² + x - 6 = 0 and factor it, resulting in x = 1.5 or x = -2. The method used is factoring due to the simplicity of the equation.

Explanation:

To solve the equation g(x) = k(x) algebraically for x, we set the given functions equal to each other. Given the functions g(x) = 2x² + 3x + 10 and k(x) = 2x + 16, the equation becomes 2x² + 3x + 10 = 2x + 16. To solve for x, we must first simplify the equation by moving all terms to one side and then using the quadratic formula or factoring, if possible.

Step 1: Subtract 2x and 16 from both sides to obtain the quadratic equation 2x² + x - 6 = 0.

Step 2: Factor the quadratic equation if possible. In this case, it factors to (2x - 3)(x + 2) = 0, so the possible solutions for x are x = 1.5 or x = -2.

The chosen method for solving this quadratic equation is factoring because the equation simplifies nicely and the factors are easily observable.
