A diagonal of a square is defined, d=a\sqrt{2} where <em>a</em> is side of the square. Solve for <em>a</em> to get a=\frac{d}{\sqrt{2}}.

Now multiply <em>a</em> by 4 since that is the definition of a perimeter,

P=4a=4\cdot\frac{18\sqrt{2}}{\sqrt{2}}=4\cdot18=\boxed{72}.

Hope this helps.

Find the common difference for the sequence shown: [1/5, 13/40, 9/20...)
bazaltina [42]
<h3>Answer:  1/8</h3>

Explanation:

Pick any term and subtract off the previous term to get the common difference.

So,

13/40 - 1/5 = 13/40 - 8/40 = (13-8)/40 = 5/40 = 1/8

Or

9/20 - 13/40 = 18/40 - 13/40 = (18-13)/40 = 5/40 = 1/8

The positive common difference value indicates this arithmetic sequence is increasing.

Eva8 [605]
About $0.75 per person.



First, let’s find the cost for each portion of hamburger meat and the cost for each bun.

We can do this for the meat by doing 1.49/4 to get 0.3725.

Now we can do the same with the buns by doing 2.99/8 to get 0.37375.

Now just add these together. 0.3725+0.37375 is 0.74625, which can be rounded to $0.75.

The cost per person is approximately $0.75.
