int to float

In this typecast we change the larger datatype into the smaller datatype in an explicit manner.

neonofarm [45]

Answer: Provided in the explanation section

Explanation:

The question says :

You are working on a documentation file userNotes.txt with some members of your software development team. Just before the file needs to be submitted, you manager tells you that a company standard requires that one blank space be left between the end-of-sentence period (.) and the start of the next sentence. (This rule does not affect sentences at the very end of a line.) For example, this is OK: Turn the knob. Push the "on" button. This is not: Turn the knob. Push the "on" button. Asking around among your team members, you discover that some of them have already typed their sentences in the approved manner, but others have inserted two or even more blanks between sentences. You need to fix this fast, and the first thing you want to do is to find out how bad the problem is. What command would you give to list all lines of userNotes.txt that contain sentence endings with two or more blanks before the start of the next sentence?

Solution:

Here, our fundamental aim is to look for the content which is having single space between different sentences. As it sentences finishing with . Going before with single and various spaces we have to channel and match just e the sentences which are finishing with ". "

For this we use order called "GREP" in Unix. "GREP " represents worldwide quest for standard articulation. This order is utilized inquiry and print the lines that are coordinating with determined string or an example. The example or indicated string that we have to look through we call it as customary articulation.

Syntax of GREP:

GREP [OPTIONS] PATTERN [FILE_NAME]

​​​​​​For our solution please follow the command

GREP "*\•\s$" userNotes.txt

Now it will display a all the lines having . Followed by single space.

Natalija [7]

Answer:

<u>Pseudocode:</u>

INPUT velocity

INPUT time

SET velocity = 0.44704 * velocity

SET acceleration = velocity / time

SET acceleration = round(acceleration, 1)

PRINT acceleration

<u>Code:</u>

velocity = float(input("Enter a velocity in miles per hour: "))

time = float(input("Enter a time in seconds: "))

velocity = 0.44704 * velocity

acceleration = velocity / time

acceleration = round(acceleration, 1)

print("The acceleration is {:.2f}".format(acceleration))

Explanation:

*The code is in Python.

Ask the user to enter the velocity and time

Convert the miles per hour to meters per second

Calculate the acceleration using the formula

Round the acceleration to one decimal using round() method

Print the acceleration with two decimal digits
