Select the correct answer.
the formula below, newton's law of cooling, allows us to calculate the temperature of an object as it cools.
t= r + (to - rjekt
t = temperature of the object after t minutes
to = initial temperature
r = temperature of the surroundings
k = cooling rate (depends on the object and conditions)
suppose the temperature in denver, colorado was 55°f when a 5°f arctic cold front moved over the state. using k = 0.012, how long would it take a
puddle of water to freeze? (recall that water freezes at 32°f.)
a
just over 51 minutes
b.
just over 55 minutes
c.
just over 61 minutes
d.
just over 65 minutes

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

step-by-step explanation:

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.
