to the risk of sounding redundant.

well, let's bear in mind that the LCD for all three fractions will just be "xyz", so then let's multiply both sides by that LCD in order to do away with the denominators and then solve for "z".

\bf \cfrac{2}{x}=\cfrac{3}{y}+\cfrac{1}{z}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{xyz}}{xyz\left( \cfrac{2}{x} \right)=xyz\left( \cfrac{3}{y}+\cfrac{1}{z} \right)}\implies 2yz=3xz+xy \\\\\\ 2yz-3xz=xy\implies \stackrel{\textit{common factor}}{z(2y-3x)}=xy\implies z=\cfrac{xy}{2y-3x}

John's dog Fido is tied to a post in his backyard. Fido's leash is 8.5 feet long. Determine how much circular roaming area Fido
ira [324]

Answer:

227 ft^2

Step-by-step explanation:

Here, we are tasked with calculating the roaming area that Fido has

Calculating this is same as calculating the area of circle that has a radius which is equal to the length of the leash

Mathematically, the area would be

A = π * r^2

A = 3.14 * 8.5^2

A = 226.865 ft^2

To the nearest square foot, this is 227 ft^2
