Ok.look.the question is like that
7:2 so first of all divide 7 by 2 like that 7/2 so you get 3.5 ok than add 3.5 with 2 so the answer is 5.5

The function below shows the number of car owners f(t), in thousands, in a city in different years t: f(t) = 0.25t^2 - 0.5t + 3.
Bingel [31]
The average rate of change (m) is the ratio of the change in function value to the width of the interval:
  m = (f(6) - f(2))/(6 - 2)

To compute this, we need to compute f(6) and f(2).
  f(6) = (0.25*6 -0.5)*6 +3.5 = 9.5
  f(2) = (0.25*2 - 0.5)*2 +3.5 = 3.5
Then the average rate of change is
  m = (9.5 - 3.5)/(6 - 2) = 6/4 = 1.5

The average rate of change is 1.5 thousand owners per year.

The Goodsmell perfume producing company has a new line of perfume and is
LenKa [72]

Given:

It is given that surface area must be less than 150 cm².

Solution:

The Maximum Volume With Total Surface Area Less  than 150 cm² is shown in the table.

From the table, it can be concluded that for r=3.00 cm and h=4.95 cm the surface area will be less than 150 cm²  and the volume will be the maximum.

S=2\pi rh+2\pi r^2\\S=2\pi (3)(7.95)+2\pi3^2\\S=93.3+56.5\\S=149.8 \text{ cm}^2

Calculate the volume.

V=\pi r^2h\\V=\pi(3)^2(4.95)\\V=139.96

Hence, the required dimensions are r=3.00 cm and h=4.95 cm.

A furniture company is producing three types of furniture. Product A requires 7 board feet of wood and 4 lbs of wicker. Product
denis23 [38]

Given:

Product A requires 7 board feet of wood and 4 lbs of wicker.

Product B requires 5 board feet of wood and 5 lbs of wicker.

Product C requires 4 board feet of wood and 3 lbs of wicker.

Available wood = 3000 board feet

Available wicker = 1400 lbs

Profit margin of A = $35 per unit

Profit margin of B = $42 per unit

Profit margin of C = $20 per unit

To find:

The linear programming problem for given situation.

Solution:

Let the number of units produced of products A, B and C are x, y and z respectively.

                                Product A       Product B           Product C      Total

Board feet of wood       7                       5                       4               3000

wicker                            4                       5                        3               1400

Objective function: Maximize z=35x+42y+20z

s.t.,

Board feet of wood  : 7x+5y+4x\leq 3000

Wicker : 4x+5y+3x\leq 1400

Number of units  cannot be negative. So, x,y,z\geq 0.

Therefore, the required LPP is

Maximize z=35x+42y+20z

s.t.,

7x+5y+4x\leq 3000

4x+5y+3x\leq 1400

x,y,z\geq 0

A manufacturer produces two models of toy airplanes. It takes the manufacturer 20 minutes to assemble model A and 10 minutes to
Georgia [21]

Answer:

A - 90 units

B = 0 units

Step-by-step explanation:

Here we have two models A and B with the following particulars

Model A B    (in minutes)

 

Assembly 20 15

Packing          10 12

Objective function to maxmize is the total profit

z=12A+8B where A and B denote the number of units produced by corresponding models.

Constraints are

20A+15B\leq 1800\\\\10A+12B\leq 1080

These equations would have solutions as positive only

Intersection of these would be at the point

i) (A,B) = (60,40)

Or if one model is made 0 then the points would be

ii) (A,B) = (90,0) oriii) (0, 90)

Let us calculate Z for these three points

A B Profit

60 40 1040

90 0 1080

0 90 720

So we find that optimum solution is

A -90 units and B = 0 units.
