Molten monsters from depths of the earth have surfaced; each has 3 heads and 47 legs. at the first meeting between humans and monsters there were 106 legs. assumings all beings had all their legs and heads, how many heads were at this meeting of the minds?

12 heads

Step-by-step explanation:

if each monster has 47 legs, then there cant be more then 2 monsters because that would be too many legs...and there cant be just 1 monsterbecause that would leave (106 - 47) = 59 legsand human legs wont add up to 59

2 monsters = (2 * 47) = 94 legsleaving (106 - 94) = 12 legs

each human has 2 legsso that means 12/2 = 6 humans.

so we have 2 monsters (each with 47 legs) + 6 humans (each with 2 legs) = 106 legs

so we have 2 monsters and 6 humanseach monster has 3 heads..and if we have 2 monsters, we have (3 * 2) = 6 heads...and if we have 6 humans, we have 6 headsso there is a total of 12 heads <

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.
