How are percents greater than 100% used in real world contexts
docker41 [41]

Answer:

Think of investments. If you were to invest $100 into a company and receive $200 dollars, then you would have made $100 in profit, which is 100% of your initial amount. So, if you were to invest $100 and receive $250 dollars in profit, then you would have made an extra $150, which is even more than your initial amount of $100. In this case, you would have made a 150% increase on your money.

Answer:

The second alternative is correct

Step-by-step explanation:

We have been given the expression;

(x^{27}y)^{\frac{1}{3}}

The above expression can be re-written as;

(x^{27})^{\frac{1}{3}}*y^{\frac{1}{3}}\\\\(x^{27})^{\frac{1}{3}}=x^{27*\frac{1}{3}}=x^{9}

On the other hand;

y^{\frac{1}{3}}=\sqrt[3]{y}

Therefore, we have;

x^{9}\sqrt[3]{y}
