Answer:

solution: let us assume that the distance from town A to town B is 100 miles

65l.g 100=65 miles

t1= 1h

t2=35/v

total time=4tt2

(17 35/v) hr.

average speed=total distance/total time

50= 65+35/1+35

50=100/v+35

50/1=100v/v+35

answer is 35.

I'm using <= as "less than or equal to", and >= as "greater than or equal to".

Let x = speed

For a car, it has to be at least 45: x >= 45 and it has to be at most 65: x <= 65

When you put these two together you have

earnstyle [38]

Answer:

z  - 2*x   -  1.5*y   =  0   maximize

subject to:

3*x  +  5*y   ≤  800

8*x  + 3*y   ≤   1200  

x, y  >  0

Step-by-step explanation:

Formulation:

Kane Manufacturing produce  x  units of model A (fireplace grates)

and  y units of model B

                  quantity   Iron cast lbs    labor (min)   Profit $    

Model  A          x               3                      8                  2

Model  B          y               5                      3                  1.50

We have   800 lbs of iron cast  and 1200 min  of labor available

We need to find out how many units  x  and units y per day to maximiza profit

First constraint   Iron cast lbs     800 lbs

3*x  +  5*y   ≤  800             3*x  +  5*y  +  s₁   =  800

Second constraint  labor    1200 min available

8*x  + 3*y   ≤   1200              8*x  + 3*y           + s₂  =  1200  

Objective function

z  =  2*x  +  1.5*y         to maximize    z  - 2*x   -  1.5*y   =  0  

x > 0   y  >  0

The first table is  ( to apply simplex method )

z         x        y       s₁      s₂       Cte

1        -2       -1.5     0      0          0

0        3         5       1       0        800

0        8         3       0       1       1200
