Is dollars 250 is to be divided among Neymar Rohit Sharma and Nadal so that Neymar gets two parts Rohit gets three parts and Nad
Hatshy [7]

Answer:

Step-by-step explanation:

Total amount of money to be shared among Neymar, Rohit Sharma and Nadal is $250

Neymar gets two parts. This means that Neymar gets 1/2 × total amount of money.

Neymar gets 1/2 × 250 = 125

The percentage will be amount that Neymar gets divided by the total amount and multiplied by 100. It becomes

125/250 × 100 = 50%

Rohit gets three parts. This means that Rohit gets 1/3 × total amount of money.

Rohit gets 1/3 × 250 = 83.33

The percentage will be amount that Rohit gets divided by the total amount and multiplied by 100. It becomes

83.33/250 × 100 = 33.33%

Nadal gets five parts. This means that Nadal gets 1/5 × total amount of money.

Nadal gets 1/5 × 250 = 50

The percentage will be amount that Nadal gets divided by the total amount and multiplied by 100. It becomes

50/250 × 100 = 20%

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.

wolverine [178]
The function for conversions from Fahrenheit to Celsius is:

Celsius = (Fahrenheit - 32) x 5/9 

C(76.1) = (76.1 - 32) x 5/9
             = (44.1) x 5/9
             =  24.5

Therefore, 76.1 degrees Fahrenheit = 24.5 degrees Celsius.
