From a board 8 feet in length, emmet cut two ,2 and 1 over3-foot bookshelves. how much of the board remained?

  5

Step-by-step explanation:

To get how much of the board remained, we simply subtract the length Emmet cut from the initial length of the board

Initial length of the board = 8

Length cut out  =    2

                         =

Length of board remained = Initial length of board - Length cut out

                                            = 8 -

                                             =

                                             =

                                          = 5

Therefore the length of the board remained  is 5 feet

  the correct choice is marked

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.
