The lp relationships that follow were formulated by richard martin at the long beach chemical company. maximize 8x1 + 0.5x1 x2 + 5x3subject to: 1x1 x2 + 2x3 ≤ 70 (c1)10.9x1 - 4x2 ≥ 156 (c2)5x1 + 3x2 + 3x3 ≥ 21 (c3)16x2 - 0.33x3 = 17 (c4)-7x1 - x2 + 4x3 = 5 (c5)1x1 + 2x2 + 3squareroot of x3 ≤ 80 (c6)for an lp, the objective function developed by richard is valid or invalidconstraint c1 is(n) valid or invalidconstraint c2 is(n) valid or invalidconstraint c3 is a(n) valid or invalidconstraint c4 is a(n) valid or invalidconstraint c5 is a(n) valid or invalidconstraint c6 is a(n) valid or invalid

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

i dont know the answer but here's a picture of a dog
