Answer:

int width_A, width_B, len_A, len_B;

float rw, rl;

rw = (float)(width_A/width_B);

rl = (float)(len_A/len_B);

if(rw == rl)

printf("They are similar");

else

printf("They are not similar");

Explanation:

The width of the first triangle i call width_A.

The width of the second triangle i call width_B.

The length of the first triangle i call len_A.

The length of the second triangle i call len_B.

The ratio of the width i call rw.

The ratio of the length i call rl.

If rw=rl, the retangles are similar. Otherwise, they are not.

The code is:

int width_A, width_B, len_A, len_B;

float rw, rl;

rw = (float)(width_A/width_B);

rl = (float)(len_A/len_B);

if(rw == rl)

printf("They are similar");

else

printf("They are not similar");

Write a sequence of statements that create a file named "greeting" and write a single line consisting of "Hello, World!" to that

tia_tia [17]

Answer:

The solution code is written in Python 3 as below:

outfile = open("greeting.txt", "w")
outfile.write("Hello World")
outfile.close()

Explanation:

To create a simple text file in Python, we can use Python built-in function, open(). There are two parameters needed for the open() function,

the file name and
a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.

The statement open("greeting.txt", "w") will create a text file named "greeting.txt" (Line 1)

To fill up the content in the greeting.txt, we use write() method. Just include the content string as the argument of the write() method. (Line 2)

At last, we use close() method to close the opened file, outfile. This will release the system resource from the outfile.

#Write a function called "replace_all" that accepts three #arguments: # # - target_string, a string in which to search. # - find

gulaghasi [49]

Answer:

Here is the function replace_all:

def replace_all(target_string,find_string,replace_string):

result_string = replace_string.join(target_string.split(find_string))

return result_string

#if you want to see the working of this function then you can call this function using the following statements:

target_string = "In case I don't see ya, good afternoon, good evening, and good night!"

find_string = "good"

replace_string = "bad"

print(replace_all(target_string, find_string, replace_string)

Explanation:

The above program has a function called replace_all that accepts three arguments i.e target_string, a string in which to search ,find_string, a string to search for and replace_string, a string to use to replace every instance of the value of find_string. The function has the following statement:

replace_string.join(target_string.split(find_string))

split() method in the above statement is splits or breaks the target_string in to a list of strings based on find_string. Here find_string is passed to split() method as a parameter which works as a separator. For example above:

target_string = In case I don't see ya, good afternoon, good evening, and good night!

find_string = good

After using target_string.split(find_string) we get:

["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night']

Next join() method is used to return a string concatenated with the elements of target_string.split(find_string). Here join takes the list ["In case I don't see ya, ", ' afternoon, ', ' evening, and ', ' night'] as parameter and joins elements of this list by 'bad'.

replace_string = bad

After using replace_string.join(target_string.split(find_string)) we get:

In case I don't see ya, bad afternoon, bad evening, and bad night!

The program and output is attached as a screenshot.

You are using a polynomial time 2-approximation algorithm to find a tour t for the metric traveling salesman problem. Which of t

Svet_ta [14]

Answer:

B. The cost of tour t is at most twice the cost of the optimal tour.

Explanation:

You are using a polynomial time 2-approximation algorithm to find a tour t for the traveling salesman problem.

The cost of tour t is at most twice the cost of the optimal tour

The equation represented as Cost(t) <= 2 Cost(T)

Where

Cost (t) represents cost of tour t

Cost(T) represents cost of the optimal tour

If a filesystem has a block size of 4096 bytes, this means that a file comprised of only one byte will still use 4096 bytes of s

jenyasd209 [6]

Answer:

Python code given below

Explanation:

def calculate_storage(filesize):

block_size = 4096

full_blocks = filesize // block_size

partial_block = filesize % block_size

if partial_block > 0:

return (full_blocks + 1) * block_size

return filesize

print(calculate_storage(1))

print(calculate_storage(4096))

print(calculate_storage(4097))
