A scale drawing has a scale of 1/4in:12ft. Find the length on the drawing for each actual length. 15 ft.
leonid [27]
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.

so, what would it be for an actual 15 feet on the drawing then?

\bf \begin{array}{ccll}
\stackrel{inches}{drawing}&\stackrel{feet}{actual}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{4}&12\\\\
d&15
\end{array}\implies \cfrac{\quad \frac{1}{4}\quad }{d}=\cfrac{12}{15}\implies \cfrac{\quad \frac{1}{4}\quad }{\frac{d}{1}}=\cfrac{12}{15}
\\\\\\
\cfrac{1}{4}\cdot \cfrac{1}{d}=\cfrac{12}{15}\implies \cfrac{1}{4d}=\cfrac{12}{15}\implies 15=48d\implies \cfrac{15}{48}=d\implies \cfrac{5}{16}=d

Suppose you are doing a binary search of the list [15, 18, 2, 19, 18, 0, 8, 14, 19, 14]. How many comparisons would you need to
Illusion [34]

Answer:

Three Times.

Step-by-step explanation:

First and foremost a binary search requires that the array be sorted in ascending or descending order.

After the initial step the search goes to the middle most value

i.e. [0, 2,8,14,14,15,18,18,19,19]  

will be the second 14, which is the first iteration.

Since 14 is less than 19 the search will eliminate  the lower half of the including 14, and will iterate again through the array:

[15,18,18,19,19]

The array will go to the middle most value which is 18, second iteration. Since 18 is less than 19, the program will eliminate the lower half and be left with two values i.e. [19,19].

The search will run once i.e. third iteration, and will return key value found.
