PM water holes can feel a pull in 30 minutes a larger waterholes Canfield the same pool in 20 minutes a clove hoses are turned on at the same time how long would it take to fill the pool

12 minutes.

Step-by-step explanation:

A water hole can fill a pull in 30 minutes and a larger hole can fill the same pull in 20 minutes.

Therefore, the small hole can fill in 1 minute the part of the pull and the large hole can fill in 1 minute the part of the pull.

So, if both the holes are open within 1 minute they will fill the tank by part of the pull.

Hence, the total pull will be filled within minutes. (Answer)

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.
