Answer:
River weight is 124.05 pounds
Step-by-step explanation:
We are given
Spot weights 75.25 pounds
so,
Spot =75.25 pounds
rover weights 48.8 pounds more than spot
so, we get
Rover = Spot +48.8
now, we can plug value
and we get
Rover = 75.25 +48.8
Rover = 124.05 pounds
So,
River weight is 124.05 pounds

Answer:
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
Wouldn't u do Multiplication? or Times?
