You are working as an apprentice for the bksb Newcastle Arena. When bands play at the arena the money made from ticket sales is split in an agreed ratio. When Phillip Cage played, £21,000 was split at a ratio of 2:5 between the arena and Phillip Cage. How much money did the arena make from Phillip Cage’s concert?

Answers

2x + 5x = 21000
7x = 21000
x = 21000/7
x = 3000

That means the money was split up

2 * 3000 = 6000
5 * 3000 = 15000

The arena got the 2 part of the ratio.
The arena got 6000 pounds. I don't have that L on my keyboard.

Final answer:

The arena therefore made £6,000 from Phillip Cage's concert.

Explanation:

To find the amount of money the arena made from Phillip Cage's concert:

Calculate the total parts in the ratio: 2 + 5 = 7 parts.Divide the total money by the total parts: £21,000 / 7 = £3,000 per part.Finally, multiply the arena's share of parts (2 parts) by the value of each part: £3,000 x 2 = £6,000.

Which of these best describes an undefined term?
A. A term that is a building block for other definitions in geometry
B. A clause in a conditional statement that begins with "then"
C. A statement that has already been proven to be true
D. A statement that is the opposite of an original statement

Answers

the answer is A hope this helps

Answer:

A. A term that is a building block for other definitions in geometry.

Step-by-step explanation:

In Geometry, undefined terms refer to concepts like point, line and plane. Which are concepts that cannot be defined, they are too intuitive. Undefined terms are always true, they cannot be prove because those concepts are too primitive.

It's important to know that Geometry develops another complex defintions from these undefined terms, beacuse point, line and plane are the fundamentals of Geometry.

Therefore, the right answer is A.

Other choices are just wrong, because undefined terms aren't condition statments, they cannot be proven and they aren't oppsite of an original statement.

Hello!

I'll solve the first two questions for you and show you how to do them step by step!

4.

We must use a certain formula to find the volume of a cylinder. The formula is:

V = pi * r^2 * h

We already have that information!

Pi = approximately 3.14

Radius = 7.5 in

Height = 3.6 in

Substitute:

(Make sure ro solve it step by step, rather than do it all at once)

V = 3.14 * 7.5^2 * 3.6

V = 176.625 × 3.6

V = 635.85

Rounded to the nearest cubic unit, the volume of this cylinder is 636 inches cubed.

**Don't forget to write a small 3 above inches to indicate that it is cubed!

5.

Aha! This time they haven't given you the radius, but the diameter.

Since the radius is half of the diameter, we must divide the diameter by 2 to find it.

r = d ÷ 2

r = 28 ÷ 2

r = 14 cm

Like the previous question, we have enough information to solve this! We'll use the same formula to calculate the volume of this cylinder.

V = pi * r^2 * h

Pi = Approximately 3.14

Radius = 14 cm

Height = 5 cm

Substitute:

V = 3.14 * 14^2 * 5

V = 615.44 * 5

V = 3,077.2 cm cubed

Rounded to the nearest cubic unit, the volume of this cylinder would be 3,077 centimetres cubed.

REMINDERS:

Use the SAME formula for all of the other questions regarding volume of a cylinder. The formula fof volume is:

V = pi * r^2 * h

Make sure you write the small 3 above it!

anna has a 10 foot long ladder that she is going to rest against a vertical wall along the bottom of a window still that is 8.5 feet above the ground. The safety code recommends that the angle the ladder makes with the ground be no greater than 65 degrees. Will the ladder be safe resting on the window still? Draw a diagram and show work to support your answer

Answers

As you can see in the picture, the ladder leaning against the wall makes a right triangle with the sides being the wall, the ground and the ladder. The ladder is opposite the right angle and so is the hypotenuse (the longest side of the triangle). The angle between the ladder and the ground is labeled a.

We know the height of the ladder (10 feet) and also the height off the ground of the windowsill (8.5 feet). That second side is opposite the angle a. So, when we consider angle a we know the length of the side opposite and of the hypotenuse.

Recall the sin of an angle can be found by using (opposite/hypotenuse).

So we have: sin a = 8.5 / 10. That is, sin a = .85
We are looking for the angle whose sin is .85 and can find this using the inverse sin function.

[tex] sin^{-1}.85=a [/tex]
a is approximately 58.211669 degrees which is less than the 65 degrees and so safe.

Just to be on the safe side, I remind you that your calculator must be in degrees (not radians) to do this problem.

Sketch a graph ofeach function. For graphs b through e, identify the information revealed by the unfactored polynomial compared to the factored polynomial.

A factored polynomial will reveal the solutions of the function because of the fact that you can set the different factors equal to 0.

An unfactored polynomial will not allow you to find the solutions, however it is easier to differentiate in case you wanted to find the turning points.

For your answer though, i recommend you just write about how a factored polynomial will reveal the solutions. (By the way, solutions are where the equation crosses the x-axis.)

Answers

The required volume of the square pyramid is 3[tex]84 cm$^3$[/tex]. The answer is option A.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,

The formula for the volume of a square pyramid is:

[tex]$V = \frac{1}{3}Bh$[/tex]

Where B is the base area and h is the pyramid's height.

In this case, the base is a square with a side length of 12 cm, so its area is:

[tex]B = 12^2 = 144cm$^2$[/tex]

The height of the pyramid is 8 cm.

Plugging these values into the formula, we get:

[tex]V = \frac{1}{3}(144)(8) = 384$ cm$^3[/tex]

Therefore, the volume of the square pyramid is 3[tex]84 cm$^3$[/tex]. The answer is option A.

Using a standard shoe size chart, the foot length for a size 10 1/2 shoe is approximately 11.1 inches when rounded to the nearest tenth of an inch.

To determine the length of the foot for a person who wears a size 10 1/2 shoe to the nearest tenth of an inch, we reference a standard shoe size chart. Shoe sizes are an approximation of the foot length they are intended to fit, with different increments representing each half-size increase. For a size 10 shoe, the approximate length is given as around 10.9 to 11 inches. Considering half sizes add approximately 1/6 of an inch, a size 10 1/2 would be approximately 11.1 inches long when measured accurately. However, shoe size to foot length can vary slightly by manufacturer, so this is a general estimate.

A square with an area of 4 in² is dilated by a factor of 7. What is the area of the dilated square?

Answers

dilated by a factor of 7 is 196 in²

Area of square if the square is s inches long is 4 in²
s² = a
s² = 4

When a square is dilated by a factor of 7, the length of side is also dilated by the factor of 7. For an instance, s₁ represents the dilated side. The equation will be
s₁ = 7s

Find the new area, the new area is represented by a₁
a₁ = s₁²
Because s₁ is equal to 7s, substitute s₁ with 7s
a₁ = (7s)²
a₁ = 7² s²
a₁ = 49s²
The value of s² is 4, substitute s² with 4
a₁ = 49(4)
a₁ = 196
The new area is 196 in²

A total of 757 tickets were sold for the school play. They were either adult tickets or student tickets. There were 57 more student tickets sold than adult tickets. How many adult tickets were sold?

Answers

350 adult tickets were sold

Final answer:

To find the number of adult tickets sold, a system of equations is created based on the total tickets sold (757) and the fact that there were 57 more student tickets sold. Solving for x gives us 350 adult tickets.

Explanation:

How to Determine the Number of Adult Tickets Sold

To determine how many adult tickets were sold for the school play when there is a known total of 757 tickets and that 57 more student tickets were sold than adult tickets, we can set up a system of equations to solve for the number of adult and student tickets. Let's let x represent the number of adult tickets, and x + 57 represent the number of student tickets since there were 57 more student tickets sold than adult tickets.

Based on the total number of tickets sold, the following equation represents this relationship:

x (adult tickets) + x + 57 (student tickets) = 757

Combining the like terms gives us:

2x + 57 = 757

Subtracting 57 from both sides gives us:

2x = 700

Dividing both sides by 2 gives us:

x = 350

So, the number of adult tickets sold is 350.
