If x = 10, which lines are parallel? Check all that apply. Lines b, c, d, e are cut by transversal a. Clockwise from top left, the angles formed by lines b and a are blank, (7 x minus 5) degrees, blank, blank; by lines c and a are blank, blank, (10 x + 15 degrees), blank; by lines d and a are (12 x minus 5) degrees, blank, blank, blank; by lines e and a are blank, (8 x minus 25) degrees, blank, blank.
b is parallel to c
b is parallel to d
b is parallel to e
c is parallel to d
c is parallel to e
d is parallel to e

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.
