Final answer:

To calculate the number of different combinations of adult and children's tickets that would total $100, we can set up an equation: 5x + 3y = 100. We can find possible values of 'x' and 'y' that satisfy the equation. There are 6 different combinations of adult and children's tickets that would have totaled $100.

Explanation:

To calculate the number of different combinations of adult and children's tickets that would total $100, we can set up an equation:

5x + 3y = 100

Where 'x' represents the number of adult tickets and 'y' represents the number of children's tickets. We need to find whole number solutions for 'x' and 'y'.

We can start by finding the possible values of 'x' and 'y' that satisfy the equation and add up to $100. The possible combinations are:

x = 0, y = 33

x = 5, y = 31

x = 10, y = 29

x = 15, y = 27

x = 20, y = 25

x = 25, y = 23

Therefore, there are a total of 6 different combinations of adult and children's tickets that would have totaled $100.

Answer:Substitute the given values in the Law of Sines and find that the measure is 24.72°

The measure of the missing angle is approximately 113.28°.

Assuming that the missing angle is opposite to side c, we can use the Law of Sines to find the measure of the missing angle. The Law of Sines states that for any triangle ABC:

a/sin(A) = b/sin(B) = c/sin(C)

Substituting the given values, we have:

16/sin(42°) = 10/sin(B) = c/sin(C)

Solving for sin(B), we get:

sin(B) = 10*sin(42°)/16 ≈ 0.4182

Using the inverse sine function, we can find the measure of angle B:

B ≈ sin⁻¹(0.4182) ≈ 24.72°

Now, we can use the fact that the angles of a triangle add up to 180° to find the measure of the missing angle:

A + B + C = 180°

A + 42° + 24.72° = 180°

A ≈ 113.28°

Therefore, the measure of the missing angle is approximately 113.28°.

The distance between the vertices of the graphs is 0.

The distance between the vertices of the graphs corresponding to y = x2 + 2 and y = 3x2 + 2 can be found by finding the x-coordinates where the graphs intersect. To do this, we set the two equations equal to each other:

x2 + 2 = 3x2 + 2

Subtracting 2 from both sides gives: x2 = 3x2

Subtracting x2 from both sides gives: 0 = 2x2

Dividing both sides by 2 gives: 0 = x2

This equation has only one solution: x = 0. Therefore, the distance between the vertices of the graphs is 0.

add the 3 and 1:

Answer:

Option C. 0.05x+0.10(x+6)=1.35

Step-by-step explanation:

Remember that

1 nickel=$0.05

1 dime=$0.10

Let

x-----> the number of nickels

y----> the number of dimes

we know that

0.05x+0.10y=1.35 -----> equation A

y=x+6 ----> equation B

substitute equation B in equation A and solve for x

0.05x+0.10(x+6)=1.35

The correct equation that can be used to determine x, the number of nickels Rhonda has, is 0.05x + 0.10(x+6) = 1.35, which is option C from the ones presented.

In this question, we are asked to find the equation that we can use to determine the number of nickels, represented by 'x', Rhonda has. Given that Rhonda has six more dimes than nickels, the cost of dimes in Rhonda's pocket can be represented by 0.10*(x+6) because each dime is worth $0.10 and she has six more dimes than nickels. Similarly, the cost of nickels in Rhonda's pocket could be represented as 0.05*x because each nickel is worth $0.05. As the total amount of money Rhonda has is $1.35, the two amounts should sum up to 1.35. Hence, the correct equation would be 0.05x + 0.10(x+6) = 1.35, so the answer is option C.

Step-by-step explanation:

A dodecahedron is a three-dimensional figure made out of 12 regular pentagons.  It resembles a soccer ball, just more rough on the edges.

So, it has 12 faces made out of regular pentagons.  Each summit/vertex is a meeting point for 3 different pentagons.

So, you can easily calculate the number of vertices:

How many pentagon vertices in total?

12 pentagons with 5 vertices / pentagon = 60 vertices in total

But each vertex meets with two others... so you have to divide the number of total vertices by 3... so 60 / 3 = 20.

The volume of the pyramid is 128 cm³

Step-by-step explanation:

* Lets revise the volume of the pyramid

- The pyramid has one base and the number of side faces depends

 on the number of sides of the base

- The volume of any pyramid is 1/3 × Area of its base × its height

* Lets solve the problem

- The pyramid has a square base

- It has four side faces all of them are triangles

- It has five vertices and eight edges

- The area of the base = s², where s is the length of the side of

  the square

- The volume of the pyramid is 1/3 × s² × h, where h is the height

 of the pyramid

- The base edge length of the base is 2 cm longer than the height

 of the pyramid

- The height of the pyramid is 6 cm

∵ The length of the edge of the base is 2 cm longer than the

   height of the pyramid

∵ The height of the pyramid (h) = 6 cm

∴ The edge length of the base = 6 + 2 = 8 cm

- The area of the base = s²

∵ s = 8 cm

∴ The area of the base (s²) = 8² = 64 cm²

- The volume of the pyramid = 1/3 × s² × h

∴ Its volume = 1/3 × 64 × 6 = 128 cm³

* The volume of the pyramid is 128 cm³

The correct answer is:

128 cm^3

The equation for slope-intercept form is y = mx + b

-mx represents the slope of the equation

-b represents the y-intercept

The slope of the two equations can be found based on what the number in front of the x is, this term is also called the coefficient.

The y-intercept is in the form of b and is substituted normally by a positive or negative integer.

Slope: 1/4 and 2

Y-intercept: 3 and 10

4=$17.60

Hole this helps :)

The unit price of a padlock, when rounded to the nearest cent, is $4.40 per padlock.

To calculate the unit price of a padlock, you'll need to determine the cost per individual padlock within a pack. In this scenario, you have a pack of 4 padlocks that costs $17.60. To find the cost of a single padlock, you can use the following formula:

Unit Price = Total Cost / Number of Padlocks

In this case:

Total Cost = $17.60

Number of Padlocks = 4

Now, let's calculate the unit price:

Unit Price = $17.60 / 4 padlocks

Unit Price = $4.40 per padlock

So, the unit price of each padlock is $4.40 when rounded to the nearest cent.

Understanding the unit price is essential for making informed purchasing decisions. It allows you to compare prices and determine whether buying in bulk (in this case, a pack of 4 padlocks) is more cost-effective than purchasing items individually.

In summary, the unit price of a padlock is $4.40 per padlock when rounded to the nearest cent. This information helps consumers assess the value of buying items in larger quantities and ensures they get the best deal for their money.

Step-by-step answer:

Given equation:

2sin(theta)cos(theta) + sqrt(3)*cos(theta) = 0  ...........................(1)

Solve for theta for 0<=theta<=2pi.

Factor out cos(theta), we get

cos(theta) * ( 2sin(theta) + sqrt(3) ) = 0

By the zero product theorem, we can conclude

cos(theta) = 0   ...................................(2)

2sin(theta) + sqrt(3) = 0  ................. (3)

Solving (2)

Answer:

Step-by-step explanation:

The equation of a parabola with its vertex at the origin can be written as ...

  y = 1/(4p)x^2

The problem statement tells us that one point on the parabola is (x, y) = (12, 9). We can put these values into the equation and solve for p, the distance from the focus to the vertex.

  9 = 1/(4p)(12^2)

  9×4/144 = 1/p = 1/4 . . . . . . . . multiply by the inverse of the coefficient of 1/p

Then p = 4, and the bulb is 4 cm from the vertex.
