The cost of a service call to fix a washing machine can be expressed by the linear function Y = 45% +35, where y represents the total cost and x represents the number of hours it takes to fix the machine. What does the slope represent? O the cost for each hour it takes to repair the machine O the cost for coming to look at the machine o the total cost for fixing the washing machine O the amount of time that it takes to arrive at the home to make the repairs

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.
