What is 5 minus 3/2 to the third power

answer choices:

1.) 13/8
2.) 9.5
3.) 18.5
4.)2197/8

13\8

Step-by-step explanation:

3\2 is 3\2 times its self 3 times.

so

3\2 x 3\2 x 3\2 = 27\8

5\1 - 27\8 this can't be done because the denominators are not the same. So you have to find the LCM which is 8.

so 5\1= 40\8

27/8 does not need to be changed.

40\8-27\8= 13\8

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.
