the inequality is:
let c denotes the number of days in a week miyoko worked as a cryptographer.
and g denotes the number of days in a week she works as a geologist.
now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.
now miyoko's goal is to earn more than $950 this week.
hence, the inequality could be represented as:
total cost for tiles and paints is $924.
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.
answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
