Rewrite this number sentence 50 1/2 divided by 1/4 using multiplication

2 answers:

This division question is asking how many 1/4 you can fit into 50 1/2.

We can fit 4 of them into 1 whole (4 x 1/4 = 1)
We can fit 8 of them into 2 wholes (8 x 1/4 = 2)

and so on.

But we have 50 1/2 wholes, so we would need 50 1/2 x 4.

The new number sentence is 50 1/2 x 4.

Answer:

The answer is 8 for part A

Step-by-step explanation:

5 1/3 divided by 2/3 is 8 because you turn it in to an improper fraction and it turns into 16/3 divided by 2/3 then you take the reciprocal of the second number and make it multiplication so 16/3 times 2/3 is 48/6. But your not done you have to simplify that into 8 so 8 is your answer.

Answer:

The domain is all real numbers and the range is all real numbers as-well.

As x approaches infinity, so does y.

As x approaches -infinity, so does y.

What is 1/2(4x+14)=2(x-7)

GREYUIT [131]

Answer:

no solution

Step-by-step explanation:

1/2(4x+14)=2(x-7)

Multiply both sides by 2.

4x + 14 = 4(x - 7)

4x + 14 = 4x - 28

Subtract 4x from both sides.

14 = -28

Since 14 = -28 is a false statement, there is no solution for this equation.

Answer: no solution

226Ra has a half-life of 1599 years. How much is left after 1000 years if the initial amount was 10 g?

Ray Of Light [21]

$\bf \textit{Amount for Exponential Decay using Half-Life}\\\\
A=P\left( \frac{1}{2} \right)^{\frac{t}{h}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &10\\
t=\textit{elapsed time}\to &1000\\
h=\textit{half-life}\to &1599
\end{cases}
\\\\\\
A=10\left( \frac{1}{2} \right)^{\frac{1000}{1599}}$
