A carpenter lays 18 square feet of tiles in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour? How would I do this problem if the options are the following choices:

A: 12 Square Feet Per Hour

B: 17 1/3 Square Feet Per Hour

C: 18 2/3 Square Feet Per Hour

D: 27 Square Feet Per Hour.

D. 27 square feet per hour

Step-by-step explanation:

Step 1:

Find the unit rate. Since 18 tiles are per 2/3 of an hour, we can divide 18 by 2 to get 9 tiles layed per third hour.

Step 2:

Multiply the 9 per third of an hour by 3 to find how many are per hour,

square feet per hour

This is called finding the unit rate of a scenario.

answer:     true

step-by-step explanation:

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.
