Clemence began studying a sample of the chemical element einsteinium-253253253, which naturally loses its mass over time. The relationship between the elapsed time, ttt, in days, since Clemence started studying the sample, and the total mass remaining in the sample, M(t)M(t)M, left parenthesis, t, right parenthesis, in milligrams, is modeled by the following function:
M(t)=200⋅(0.96)t
Complete the following sentence about the daily rate of change in the mass of the sample.

i think the answer is d im not sure

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.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
