the area of this figure is?

Answer:

Step-by-step explanation:

Lets denote number of floor tickets by x and

Lets denote number of balcony tickets by y as shown in the figure in the question

so, floor tickets are sold for $15 each which means number of x tickets would be sold by $15 multiplied by x which means 15x and balcony tickets are sold for $12 each which means number of y tickets would be sold by $12 multiplied by y which means 12y furthermore it says they want to make at least $3000 which would mean they want to make at least $3000 or higher meaning ≥3000 so the inequality would be

a) [tex]15x+12y\geq 3000[/tex]

b) The ordered pair A we can see that A is the y-intercept which means the point A can also be written as (0 , y) so we put this point into our equation

15x + 12y = 3000 which is the boundary line. So here goes,

[tex]15x+12y=3000\\15(0)+12(y)=3000\\12y=3000\\y=3000/12\\y=250\\[/tex]

so our y-intercept is 250 which means Point A is (0 , 250)

c) They should  shade the area above the boundary line because in this context the band that is playing wants to make at least $3000 which means they want to make more than $3000 . So when a ≥ sign appear we shade the area above the boundary line and when the ≤ sign appears we shade the area below the boundary line. If it were in the question the bands wants to make at most $3000 then the ≤ would appear.

I have attached a graph to clearly visualize the solution as well.

Answer:

0.5

Step-by-step explanation:

Distance of OL = 0 - (-5)

                         = 0 + 5

                         = 5

Distance of OK = 2(5)

                          = 10

Gradient = [tex]\frac{rise}{run}[/tex]

               = [tex]\frac{0-(-5)}{10-0}[/tex]

               = [tex]\frac{5}{10}[/tex]

               = 0.5

Answer:

  11. y = -1/4x² +1

  12. y = 1/6(x -3)² +5/2

Step-by-step explanation:

Since 9-12 are all the same, we can solve the problem generically and plug in the given numbers. Let the focus be (a, b) and the directrix be y=d.

The vertex is halfway between the focus and directrix, so its coordinates will be (a, (b+d)/2). The distance from focus to directrix is b-d. Given these conditions, the equation of the parabola is ...

  y = 1/(2(b-d))(x -a)² +(b+d)/2

__

11. For (a, b) = (0, 0) and d = 2, the equation is ...

  y = 1/(2(0-2))(x -0)² +(0+2)/2

  y = -1/4x² +1

__

12. For (a, b) = (3, 4) and d = 1, the equation is ...

  y = 1/(2(4-1))(x -3)² +(4+1)/2

  y = 1/6(x -3)² +5/2

__

The attachments show the graphs of these. You can verify the graph by noticing ...

  a) the vertex is halfway between the focus and directrix

  b) a horizontal line from the focus to the curve is the same length as a vertical line from the directrix to the same point on the curve

Answer:

c is the correct answer i took the test

Step-by-step explanation:

The gender that shows greater variability in their playing time is C. Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

For the males, the interquartile range will be:

= Third quartile - First quartile

= 17 - 9

= 8

For the females, the interquartile range will be:

= Third quartile - First quartile

= 15 - 3

= 12

Therefore, girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.

Answer:

No solution

Reason:

A solution would be the point at which the lines cross.

These lines have the same negative slope and are parallel to one another. This means they will never cross. This means there is no solution.

Answer:

A) The number of wallpapers needed to cover the walls is 6 double roll wall papers

B) The number of wall paper border rolls needed is 3 rolls

Step-by-step explanation:

A) The given parameters are;

The dimensions of the room are 9 ft. by 12 ft. by 8 ft. high,

The area one double role wallpaper covers = 60 ft.²

Therefore, we have;

The area of the room wall = 12 × 8 × 2 + 9 × 8 × 2 = 336 ft²

The number of double rolls of wallpaper to be used = Area of wall/(area of wallpaper) = 336/60 = 5.6

Therefore, given that the wall papers are sold in single units, we round up to the next whole number of units to get;

The number of wallpapers needed to cover the walls = 6 double roll wall papers

B) The borders of a wallpaper are installed parallel (and installed along) to the ceiling line

Therefore, the amount of wallpaper border required is given as follows;

Wall paper border length required = 2 × Length of the room + 2 × Width of the room

∴ Wall paper border length required = 2 × 9 ft. + 2 × 12 ft. = 42 ft.

The size of each wall paper border sold = 5 yd. = 15 ft.

Therefore;

The number of wall paper border rolls required = 42 ft./(5 yd.) = 42 ft./(15 ft.) = 2.8 rolls

Therefore, we round up to get the number of wall paper border rolls needed as 3 rolls of wall paper borders.

Answer:

slope = (-2 +3) / (12 -3)

Step-by-step explanation:

Initial dimension of a sand castle is 54 inches by 77 inches. Mike decided to change the size, making it 112 inches by 38 inches.

He wanted to dug a moat around it.

The perimeter of moat with initial dimensions,

P = 2(54+77)

= 262 inches

The perimeter of moat with new dimensions,

P = 2(112+38)

= 300 inches

Difference in perimeter = 300 - 262

= 38 inches

Hence, the new dimension is 38 inches longer than the initial dimensions.

14 pounds of meat

Step-by-step explanation:

Jose has 4 5/6 pounds of chicken, 3 1/3 pounds of steaks and 5 5/6 pounds of hamburgers to put on the grill. How many pounds of meat does he have for the barbecue

We have to find the sum of the the total pounds of meat.

This is calculated as:

4 5/6 pounds + 3 1/3 pounds + 5 5/6 pounds

[(4 + 3 + 5) + (5/6 + 1/3 + 5/6)] pounds

The Lowest Common Denominator

= 6

Hence:

[12 + (5 + 2 + 5 /6)] pounds

= 12 + 12/6

= 12 + 2

= 14 pounds of meat

Hence, Jose has 14 pounds of meat
