Acompany produces regular and deluxe ice cream at three plants. per hour of operation,

plant a produces 40 gallons of regular ice cream and 20 gallons of deluxe ice cream.

plant h produces 20 gallons of regular ice cream and 40 gallons of deluxe ice cream,

and plant m produces 40 gallons of regular and 40 gallons of deluxe.

it costs $60 per hour to operate plant a, $92 per hour to operate plant h, and $140 per hour to operate plant m. the company must produce at least 350 gallons of regular ice cream and at least 240 gallons of deluxe ice cream each day. to minimize the cost of production, plant a should operate for hours per day, plant h should operate for hours per day, and plant m should operate for hours per day. (round to the nearest tenth as needed.)

Answer explained below

Step-by-step explanation:

Let a be the working hours of plant A.

Let b be the working hours of plant H.

Let c be the working hours of plant M.

We have to minimize , Z = 60a + 92b + 140c

subject to constraint , 40a + 20b + 40c >=350

                20a + 40b + 40c >=240

where a>=0 , b>=0 ,c>=0

So ,by solving this , a = 7.67 , b= 2.17 , c = 0

So ,working hours of plant A = 8 hrs

working hours of plant H = 3 hrs

working hours of plant M = 0 hrs

A = 8hrs  

H = 3hrs  

M = 0hrs  

Step-by-step explanation:

Let a be the working hours of plant A.  

Let b be the working hours of plant H.  

Let c be the working hours of plant M.  

∴ Hours of plants A,H,M are a,b,c respectively.  

We have to minimize the cost of production, Z = 60a + 92b + 140c  

Regular ice cream: 40a + 20b + 40c = 350  

Deluxe ice cream: 20a + 40b +40c =240  

Where a>=0, b>=0, c>=0  

So, by solving this, a= 7.67, b= 2.77,c= 0  

So working hours of plant A = 8 hrs  

Working hours of plant H = 3 hrs  

Working hours of plant M = 0 hrs  

option: d is correct

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
