<h3>Answer:</h3>

a. \frac{5}{4}

b. \frac{3}{2} or 1\frac{1}{2}

<h2>Steps:</h2><h3><u>For a.)</u></h3>
  • Apply radical rule: \sqrt[n]{\frac{a}{b} }  =\frac{\sqrt[n]{a}}{\sqrt[n]{b} }, assuming a\geq 0,b\geq 0

  • = \frac{\sqrt{25} }{\sqrt{16} }

\sqrt{16}=4

\frac{\sqrt{25} }{4}

\sqrt{25} =5

=\frac{5}{4}

<h3><u>For b.)</u></h3>
  • \frac{\sqrt{18} }{\sqrt{8} }

  1. Apply radical rule: \frac{\sqrt{a} }{\sqrt{b} } =\sqrt{\frac{a}{b} }

  • Which means\frac{\sqrt{18} }{\sqrt{8} }=\sqrt{\frac{18}{8} }

=\sqrt{\frac{18}{8} }

2. Cancel \frac{18}{8}: \frac{9}{4}

= \sqrt{\frac{9}{4} }

Now apply the radical rule: \sqrt[n]{\frac{a}{b} } =\frac{\sqrt[n]{a} }{\sqrt[n]{b} }  assuming a\geq 0,b\geq 0

  • = \frac{\sqrt{9} }{\sqrt{4} }
<h2 />

\sqrt{4}=2

=\frac{\sqrt{9} }{2}

\sqrt{9}=3

The final answer for b.) should be \frac{3}{2}

Jed wants to earn 25% annual net income on his $50,000 cash investment in property his annual expense of owning the property are
Elena L [17]

Answer: $1,842

Step-by-step explanation:

John wants to earn 25% of his investment of $50,000 which is:

= 25% * 50,000

= $12,500

He has expenses of $9,600 yearly so the rent he should charge per year in order to make his 25% requirement as income is:

= Expenses + Return

= 9,600 + 12,500

= $22,100

Rent per month is:

= 22,100 / 12

= $1,842

3. What is the radius of a circle whose area is 64π cm squared?
nataly862011 [7]

Answer:

Area = 64π

Area \: = \pi {r}^{2}Area=πr

2

64 \: \pi \: = \pi {r}^{2}64π=πr

2

{r}^{2} = \dfrac{64\pi}{\pi}r

2

=

π

64π

{r}^{2} = 64r

2

=64

r \: = \: \sqrt{64} = 8r=

64

=8

Radius = 8 units

Finding the Diameter -

Diameter = Radius x 2 = 8 x 2 = 16 .

\bold{Diameter \: is \: 16 \: units}Diameteris16units
