(b) 156.5 cm

Step-by-step explanation:

1. In 5th grade, Ali was 136.5 cm, then in 6th, grade he was 141.5 cm. Now, in 7th grade, Ali is 146.5 cm. As you can see, Ali's height increases 5 cm per grade.

2. Since 9th grade is in two years, we add 10 cm to Ali's 7th grade height.

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.
