Answer:

7) \frac{x+20}{x}=\frac{46}{30}

30(x+20)=46x

30x+600=46x

46x-30x=600

16x=600

x=75/2

x=37.5

---------------------

8) \frac{10}{3x+1} =\frac{22}{7x-1}

10(7x-1)=22(3x+1)

70x-10=66x+22

70x-66x=22+10

4x=32

x=\frac{32}{4}

x=8

<u>---------------------</u>

hope it helps...

have a great day!!

A hotel wants to put a fence around a circular spa. The radius of the spa is feet. If the fence is built along the immediate edg
MariettaO [177]

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

P = 2 \pi*r

Where "r" represents the radius of the circle, in this case r = \frac {5} {\sqrt {2} -1}

Substituting in the perimeter equation we have:

P = 2 \pi * \frac {5} {\sqrt {2} -1}

Rationalizing we have:

P = \frac {2 \pi * 5 (\sqrt {2} +1)} {(\sqrt {2} -1) * (\sqrt {2} +1)}\\P = \frac {2 \pi*5 \sqrt {2} +2 \pi*5} {2-1}\\P = 10 \pi \sqrt {2} +10 \pi

Taking out common factor \pi:

P = (10 \sqrt {2} +10) \pi

Answer:

P = (10 \sqrt {2} +10) \pi\ feet
