Write 2.3181818... as a mixed number
JulsSmile [24]
Let x= 2.3181818...

then

10x=23.181818...     and

1,000x=2,318.1818...


1,000x-10x=2,318.1818...-23.181818...

       990x = 2,318 - 23
       990x = 2295
           
           x=2295/990

dividing by 5 both numerator and denominator:

               x= 459/198

now, x= 198 + 198+ 63

so x= 2\frac{63}{198}


Answer: x= 2\frac{63}{198}

If one side of a cube is 15m in length,find its volume
sergeinik [125]

Answer:

V = 3375~m^{3}

Step-by-step explanation:

The formula of the volume of a cube is V = a^{3} where "a" would correspond to the length of an edge/side/height/etc.

If we insert our value into the formula, we get the following result:

V = a^{3}

V = 15m^{3}

V = 3375~m^{3}~(cubic~meters)

Hope it helped,

HELP ME PLEASE
solmaris [256]

Answer:

The initial mass of the sample was 16 mg.

The mass after 5 weeks will be about 0.0372 mg.

Step-by-step explanation:

We can write an exponential function to model the situation.

Let the initial amount be A. The standard exponential function is given by:

P(t)=A(r)^t

Where r is the rate of growth/decay.

Since the half-life of Palladium-100 is four days, r = 1/2. We will also substitute t/4 for t to to represent one cycle every four days. Therefore:

\displaystyle P(t)=A\Big(\frac{1}{2}\Big)^{t/4}

After 12 days, a sample of Palladium-100 has been reduced to a mass of two milligrams.

Therefore, when x = 12, P(x) = 2. By substitution:

\displaystyle 2=A\Big(\frac{1}{2}\Big)^{12/4}

Solve for A. Simplify:

\displaystyle 2=A\Big(\frac{1}{2}\Big)^3

Simplify:

\displaystyle 2=A\Big(\frac{1}{8}\Big)

Thus, the initial mass of the sample was:

A=16\text{ mg}

5 weeks is equivalent to 35 days. Therefore, we can find P(35):

\displaystyle P(35)=16\Big(\frac{1}{2}\Big)^{35/4}\approx0.0372\text{ mg}

About 0.0372 mg will be left of the original 16 mg sample after 5 weeks.
