The answer is B.

Consider the fraction $\frac{6 \sqrt{5} }{\sqrt{5}}$ .

Both the numerator and denominator, when by themselves, are irrational.

However, when they are divided, they result in the rational number $\frac{6 \sqrt{5} }{\sqrt{5}}=\boxed{6}$ .

When $p,q$ have the same irrational factor, the irrational factor will be cancelled from the fraction and (possibly) leave a rational number.

Last month, Belinda worked 160 hours at a rate of $10.00 per hour. If her employer retains 9% of her gross salary, is $1,500 a r

sleet_krkn [62]

We have been given that last month, Belinda worked 160 hours at a rate of $10.00 per hour.

Let us find amount earned by Belinda last month as:

$\text{Amount earned in 160 hours}=\$10\times 160$

$\text{Amount earned in 160 hours}=\$1600$

We are also told that Belinda's employer retains 9% of her gross salary. This means that Belinda's net income will be 91% of $1600. $(100\%-9\%=91\%)$ .

$\text{Belinda's net income would be}=\$1600 \times \frac{91}{100}$

$\text{Belinda's net income would be}=\$16\times 91$

$\text{Belinda's net income would be}=\$1456$

Upon rounding $1456 to nearest hundred, we will get:

$\text{Belinda's net income would be}\approx \$1500$

Therefore, $1500 is a reasonable estimate of her net salary.
