List the next three numbers for the sequence: 7, 7 2 , 7 4 , 7 8

7/16, 7/32, 7/64

Step-by-step explanation:

7, 7 /2 , 7/ 4 , 7/ 8

We multiply by 1/2 each time

7/8 *1/2 = 7/16

7/16*1/2 = 7/32

7/32 *1/2 = 7/64

the first one

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.
