A new concert venue just opened in downtown Augusta and they are in the process of deciding how many tickets they can sell for each show. The venue has three levels, two general admission that only have standing room, and one level with 240 seats. The first level of standing room is a square with one side measuring 80'. The second level, also standing room, is a rectangle measuring 120' by 30' ft. The third level has 240 seats. The venue thinks each person will occupy 2.5 square feet. How many tickets should they sell?

Answers

Answer:

4,240 tickets

Step-by-step explanation:

The first level of standing room is a square with one side measuring 80'.

Area of the first level = length^2

= 80^2

= 6,400 square ft

The second level, also standing room, is a rectangle measuring 120' by 30' ft.

Area of the second level = length × width

= 120 × 30

= 3,600 square ft

Total area of the standing rooms = (6,400 + 3,600) square ft

= 10,000 square ft

Each person in the standing room will occupy 2.5 square ft

Number of Persons that will occupy the standing room = Total area of the standing rooms / 2.5 square ft

= 10,000 square ft / 2.5 square ft

= 4,000

Therefore the number of Tickets that should be sold

= Number of seats + Number for standing Room

= 240 + 4000

= 4,240 tickets

A sweater that originally cost $40 is on sale for 10 percent off. What is the amount of the discount?

Answers

Answer:

$36

Step-by-step explanation:

orig price = $40

discount=10%

40*10/100= 400/100 = 4

$40-4= $36

Answer:

$4

Step-by-step explanation:

x percent = x/100

10 percent = 10/100 = 0.10

10% of $40 = 0.10*40 = 4

You save $4

The old price is $40 and changes to $36 after the discount is applied. This is ignoring any taxes or other surcharges

Anyways I'm going a bit off tangent. The final answer is choice B) $4

Ernie earned $121.50 more than Kaylin. Tria earned $35 less than 3 times the amount Kaylin earned. Ernie, Tria, and Kaylin earned $579 in all. How much did Tria earn?
$98.50
$220.00
$260.50
$330.50

Answers

x - Ernie, y - Kaylin, z - Tria

x = y + 121.50

z = 3y - 35

x + y + z = 579

-------------------------

z = 3 y - 35      =>   - 3 y + z = -35

y + 121.50 + y + z = 579

---------------------------------

- 3 y + z = - 35        / · ( -1 )

 2 y + z = 457.50     (we will use the elimination method) 

---------------------------------

3 y - z = 35

2 y + z = 457.50

----------------------

5 y = 492.5,            y = 492.5 : 5 = 98.5

z = 3 · 98.5 - 35

z = 260.5

Tria earned $260.5 

C)260.50
Step by step explanation
Let "x" be the amount earned by Ernie
Let "y" be the amount earned by Kaylin
Let "z” be the amount earned by Tria

Now let’s form the equations

x=y + 121.50 (1)

z=3y- 35 (2)

x + y + 2= 579 (3)

Now plug in x = y + 121.50, in the third equation.

y + 121.50 + y + z =579

2y + z = 457.50

From the second equation 3y - z = 35

2y + z =457.50

3y - z = 35

5y = 492.5

Dividing both sides by 5 we get

y = 98.50

Now let’s find how much Tria earned.

z = 3*98.5 - 35

z = $260.50

A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of addition B) Commutative property of addition C) Multiplicative property of equality D) Distributive property of multiplication over addition

Answers

Given:

The statements and reasons to solve an equation.

To find:

The missing reason.

Solution:

If a, b and c are three real number, then

Associative property of addition : [tex](a+b)+c=a+(b+c)[/tex]

Commutative property of addition : [tex]a+b=b+a[/tex]

Multiplicative property of equality : [tex]a=b\Leftrightarrow ca=cb[/tex]

Distributive property of multiplication over addition : [tex]a(b+c)=ab+ac[/tex]

In the given step, [tex](x+-3)+3[/tex] is written as  [tex]x+(-3+3)[/tex].

It means, only parenthesis are changed, which is possible by Associative property of addition.

So, the missing reason is Associative property of addition.

Therefore, the correct option is A.

Divide.

slope of 1/2 that passes through the point (6,-4) in slope-intercept form

Answers

Answer:

y=1/2x-7

Step-by-step explanation:

slope intercept form: y=mx+b

mx= slope

b= y-intercept

y=1/2x+b

Now plug in 6 for x and -4 for y bc 6 is in the x-value and -4 is in the y-value.

-4=1/2(6)+b

-4=3+b

Subtract 3 from both sides

b=-7

y=1/2x-7

The equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

To find the equation of a line with a slope of 1/2 that passes through the point (6, -4), we can use the point-slope form of a linear equation, which is:

y - y₁ = m(x - x₁)

Plugging in the values, we have:

y - (-4) = 1/2(x - 6)

y + 4 = 1/2(x - 6)

Now, let's convert the equation to slope-intercept form, which is in the form of y = mx + b, where m represents the slope and b represents the y-intercept.

Expanding and rearranging the equation:

y + 4 = 1/2x - 3

y = 1/2x - 7

Therefore, the equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

Which statements about experimental probability are true? Select three options.

A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.
B: Experimental probability is the same as theoretical probability.
C: An experiment to determine probability will include a number of trials.
D: A probability experiment will count the number of times an event occurs.
E: Experimental probability can be written in the form of a ratio.

Answers

Answer:

I don't know this exactly, but I'll give it my best go!

We can get the answer by answering questions we know are true and eliminating the ones we don't.

E: Experimental probability can be written in the form of a ratio.

- Any probability can be expressed by a ratio so this is true.

B: Experimental probability is the same as theoretical probability.

- They are two different 'types' of probability so this is most likely false.

A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.

- I'm fairly certain that applies to theoretical probability, not experimental.

So that means the answers are most likely C, D, and E. If I was wrong let me know!

The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.

In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.

The second term in choice C is Circle, so choice C is the answer.

Of course, you can also list them all out.

If there is no remainder when you divide then the 12th term is the last term in the sequence.
