Answer:

The value of f out of given expression d=16ef^2 is \frac{\pm 1}{4}\sqrt{\frac{d}{e}}

Step-by-step explanation:

Given : expression d=16ef^2

We have to solve for f.

Consider the given expression  d=16ef^2

Divide both side by 16e, we get,

\frac{d}{16e}=f^2

Now, taking square root, both sides, we have,

\sqrt{\frac{d}{16e}}=\sqrt{f^2}

Simplify, we get,

\sqrt{\frac{d}{16e}}=f

We know \sqrt{16}=\pm 4 , we get,

\frac{\pm 1}{4}\sqrt{\frac{d}{e}}=f

Thus, The value of f out of given expression d=16ef^2 is \frac{\pm 1}{4}\sqrt{\frac{d}{e}}

Answer: f=\pm \frac{\sqrt{de}}{4e}

Step-by-step explanation:

Here, the given expression is,

d=16ef^2

or 16ef^2=d

\implies f^2 =\frac{d}{16e}

\implies f=\pm\sqrt{\frac{d}{16e}}

\implies f =\pm \frac{\sqrt{d}}{4\sqrt{e}}

\implies f= \pm \frac{\sqrt{de}}{4e}  ( By rationalization )

Which is the required value of f.

Rainbow [258]

Answer:

You would need thirteen and a half( 13\frac{1}{2}) cups of flour.

Step-by-step explanation:

You can find this by taking 4\frac{1}{2} and multiplying it by 3, since 24/8=3. This gives you 13\frac{1}{2} .

How do I answer this question
soldi70 [24.7K]

The answer is C. 2.

This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to 4^\frac{3}{2}.

\frac{4^\frac{3}{2}}{4^\frac{1}{2}}=4., using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.

Now, we reduced the fraction, so all that is left is (4)^\frac{1}{2}. This is equal to 2.

So your answer is 2.

I hope this helps :)

Divide 5 in a ratio of 1:2:3
anastassius [24]
In plain and short, we simply divide 5 by (1+2+3) and then distribute the pieces likewise

\bf 5\qquad 1:2:3\qquad \cfrac{5}{1+2+3}\implies \cfrac{5}{6}
\\\\\\
\stackrel{\textit{ratio of 1}}{1\left( \frac{5}{6} \right)}\qquad \stackrel{\textit{ratio of 2}}{2\left( \frac{5}{6} \right)}\qquad \stackrel{\textit{ratio of 3}}{3\left( \frac{5}{6} \right)}\qquad \implies \qquad \frac{5}{6}~:~\frac{5}{3}~:~\frac{5}{2}

add the ratios up, and you'll get 5.
