How long will it take 5000 to double in an account that pays 5.6% simple interest

Ganezh [65]

So... doubling 5000 is just 10,000, thus

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$10,000\\
P=\textit{original amount deposited}\to& \$5,000\\
r=rate\to 5.6\%\to \frac{5.6}{100}\to &0.056\\
t=years
\end{cases}
\\\\\\
10000=5000(1+0.056t)\implies \cfrac{10000}{5000}=1+0.056t
\\\\\\
2=1+0.056t\implies 1=0.056t\implies \cfrac{1}{0.056}=t$

Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minute

TiliK225 [7]

The Goblin Girt take 15 minutes to count the coins in the bag alone if Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minutes.

<h3>What is a fraction?</h3>

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let's suppose the Goblin Girt take x minutes to count the coins in the bag alone.

Then we can frame an equation to find the value of x:

$\rm \dfrac{1}{x}+\dfrac{1}{10}=\dfrac{1}{6}$

$\rm \dfrac{1}{x}=- \dfrac{1}{10}+\dfrac{1}{6}$

$\rm \dfrac{1}{x}=\dfrac{1}{15}$

x = 15 minutes (reciprocal on both sides)

Thus, the Goblin Girt take 15 minutes to count the coins in the bag alone if Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minutes.

Apply Laws of Exponents to write an equivalent expression.<br> (3y)-4. (2z)-4

Stels [109]

After Applying Laws of Exponents we can write as $(6yz)^{-4}$

<h3>What is law of exponents ?</h3>

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 34 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. A whole number, fraction, negative number, or decimal are all acceptable.

<h3>How are powers of powers multiplied?</h3>

Exponents with distinct bases and the same powers can be multiplied by multiplying the bases and writing the power outside of the brackets.

$a^{n}$ . $b^{n}$ = $(a.b)^{n}$
