Find the coordinates of the intersection of the diagonals of parallelogram wxyz with the following vertices: w (-1, 7), x (8, 7), y (6, -2) and z (-3, -2) a) (1.5, -2) b) (7, 2.5) c) (2.5, 2.5) d) (3.5, 7)

The diagonals bisect each other at their midpoints.

Find the midpoint of diagonal WY :-

= (-1+6/,2 , (7-2)/2

= (2.5, 2.5) answer

Its C

step-by-step explanation:

because that's the answer

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.
