What is the new position of the drone relative to the top of the building?

The new position of the drone relative to the top of the building would be:

Hence, option (B) is correct.

Step-by-step explanation:

Given that a drone flies up ft above the top floor of a building.

As it flies away from the building and goes down .

Thus, the new position becomes

The LCM of 4,8: 8

Adjusting fractions based on LCM

Converting improper fractions to mixed numbers

THEN IT RISES ANOTHER and HOVERS onwards:

As the drone rises again another ft, the final position can be calculated by adding ft in ft.

i.e

The LCM of 8, 2: 8

Adjusting fractions based on LCM

Converting improper fractions to mixed numbers

Therefore, the new position of the drone relative to the top of the building would be:

Hence, option (B) is correct.

probably the last option

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.
