3. 16.4: Green's theorem. This theorem is about integrals around closed loops, for non-conservative planar vector fields. It is a fundamental theorem for double integrals. In other words, suppose that D is a set in the plane and you want to compute If there is a vector field F = P(x, y)i + Q(x, y)j so that

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

10

step-by-step explanation:

7+3=10

the answer is 21%.

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.
