ANSWER TO QUESTION 1

Just substitute

y=8

in to

That means everywhere we see

we replace it with

.

This gives us,

g(8)=2(8)+7

The correct answer is B

ANSWER TO QUESTION 2

We first find the area of the sitting area.

From the diagram, the sitting area has the following dimension.

Length=700ft

and

.

Since the sitting area is rectangular in shape, we use the formula for finding the area of area of a rectangle.

That is ,

A=lw

.

We substitute the dimension to obtain,

$A=525\times 700$

$\Rightarrow A=367,500ft^2$

Since each person occupies 2 square feet, we divide by 2

A=183,750

The correct answer is C

ANSWER TO QUESTION 3.

The question 2and 3 are the same.

Answer from: debrielcalderon

1. Option B.

2. Option D.

3. Option C.

Step-by-step explanation:

(1)

The given function is

g(y)=2y+7

Substitute y=8 to find the value of g(8).

g(8)=2(8)+7=16+7=23

The value of g(8) is 23. Therefore, the correct option is B.

(2)

Area of a rectangle is

$Area=length\times width$

From the given figure it is clear that the length of the seating area is 700 ft and width of the seating area is 525 ft.

The total seating area is

$Area=700\times 525$

Area=367500

The seating are is 367500 ft².

According to the “rule of thumb,” circulation Area comprises roughly 25 to 40% of the total Usable Area.

40 % of total area is

$367500\times \frac{40}{100}=147000$

Using a standard rule of thumb the attendance is 147,000 People.

Therefore, the correct option is D.

(3)

Each person takes up 2 square feet. Then the total number of persons is

$People=\frac{367500}{2}$

People=183750

Therefore, correct option is C.
