Please help!!: Given PQ with P(−2, 5) and Q(6, 2), find point R on PQ such that PRRQ=35. Justify your response.

A. R(a, b) can be found using a=−2+35(8) and b=5+35(−3) to get R(2.8, 3.2)

B. R(a, b) can be found using a=6+35(−8) and b=2+35(3) to get R(1.2, 3.8).

C. R(a, b) can be found using a=6+35(8) and b=2+35(−3) to get R(10.8, 0.2).

D. R(a, b) can be found using a=−2−35(8) and b=5−35(−3) to get R(−6.8, 6.8).

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.
