Use proportional math. 12 is to $36 as 8 is to ___. Or 12/36 is to 8/X.

Find the length of the missing side using the pythagorean theorem
fenix001 [56]

Answer:

3

Step-by-step explanation:

Pythagorean Theorem: a²+b²=c²

You can fill in the numbers you know: a²+4²=5²

(Hypotenuse must be side c)

Square those numbers and you have: a²+16=25

Subtract 16 from both sides: a²=9

Square root both sides and you get: a=3

Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden. Zaid agreed to construct 20% more of
likoan [24]

Answer:

1.2x +x =792

2.2x =792

And we got finally:

x =\frac{792}{2.2}= 360 ft

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft

Step-by-step explanation:

For this case we know that Zaid and Matias, two farmers, constructed a 792 foot fence around their very large garden so then the total is represented by 792 ft

We also know that Zaid agreed to construct 20% more of the fence than Matias did. Let's assume that the amount that construct by Matias was x then the amount constructed by Zaid would be 1.2 x representing 20% more than Matias and we can set up the following equation:

1.2x +x =792

2.2x =792

And we got finally:

x =\frac{792}{2.2}= 360 ft

And the amount for Zaid would be 1.2*360 ft= 432ft

So then Zaid construc 432 ft and Matias 360 ft
