What is a rational number that is located between 31.5 and 31.6

the rational number between 31.5 and 31.6 is 31.55

Step-by-step explanation:

Now, we know that, average of the given numbers will lie in between the given numbers.

And, as we are finding average, which means sum divided by 2, it can be written in form.

So, it will be an rational number between given numbers.

Then, average of 31.5 and 31.6 =

Average =

Average = 31.55  

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.
