Triangle x y z is shown. angle z w x is a right angle. an altitude is drawn from point w to point y on side z x to form a right angle. the length of w y is 4, the length of y x is a, the length of z y is 3, the length of z w is c, and the length of w x is b. what is the value of a? 5 units 5 and one-third units 6 and two-thirds units 7 units

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.

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
