The spread of a disease can be modeled as n=200 Square root t, where n is the number of infected, and t is the time(in days). How long will take until the number of infected people reaches 1400

49 days

Step-by-step explanation:

The spread of the disease is modeled as

where n = number of infected people

t = time (in days)

When the number of infected people is 1400, the number of days t will be:

It will take 49 days for the number of infected people to reach 1400.

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

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.
