20. A cannonball is shot from a cannon on top of a hill that is 73.5 meters above sea level. The cannonball leaves the cannon with a velocity of 9.8 m/s. Write and solve a
quadratic equation to determine when the cannonball will reach sea level.

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

f is the midpoint of

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.

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
