An office building has 8 floors above the ground. on a line graph that models the average number of times the elevator stops on each floor each day, which values will be the x-coordinates?

D = {1, 2, 3, 4, 5, 6, 7, 8}

Step-by-step explanation:

The x-coordinates are the domain values for the function.

There is no 0 floor. The floors are not negative.

The correct answer is D = {1, 2, 3, 4, 5, 6, 7, 8}.

Answer choice on USA Test Prep is A

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.
