The Ferris wheel at the landmark Navy Pier in Chicago takes 7 minutes to make one full rotation. The height H in feet above the ground of one of the six-person gondolas can be modeled by:
H(t) = 70sin 27 (t – 1.75) + 80, where t is time in minutes. If you are loaded onto the gondola at 11 AM,
how far off the ground will you be at 11:10? Round to the nearest tenth of a foot.

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.
