Steelco manufactures two types of steel at three different steel mills. during a given month, each steel mill has 200 hours of blast furnace time available. because of differences in the furnaces at each mill, the time and cost to produce a ton of steel differs for each mill. the time and cost for each mill are shown in table 1. each month, steelco must manufacture at least 500 tons of steel 1 and 600 tons of steel 2. formulate an lp to minimize the cost of manufacturing the desired steel. also clearly define the decision variables
steel 1 steel 1 steel 2 steel 2
cost time (minutes) cost time (minutes
mill 1 $10 20 $11 22
mill 2 $12 24 $9 18
mill 3 $14 28 $10 30

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

answer: i think one of the answer is $150 and $300?
