Why is knowledge of percent composition important in the mining process?

1 answer:

8 0

I would assume there is a minimum composition threshold to make the mining operation profitable. A company will not stay in business by spending more on the mining operations than they receive in revenue by selling the material.

Suppose that the tuition for a university is $10,000 this year and increases 4% every year. In one year, the tuition will be $10

seropon [69]

Answer:

The programming language is not stated; however, I'll answer using Python programming language (See attachment for proper format)

tuition = 10000

rate = 0.04

for i in range(1,15):

tuition = tuition + tuition * rate

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

Explanation:

The first 2 lines initializes tuition and rate to 10000 and 0.04 respectively

tuition = 10000

rate = 0.04

The next line iterates from year 1 to year 14

for i in range(1,15):

This line calculates the tuition for each year

tuition = tuition + tuition * rate

The next 3 lines prints the tuition for year 1 to year 10

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

The next 3 lines prints the tuition at the 4th year after year 10 (i.e. year 14)

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

Which avenue may utilize video streaming, audio narration, print designs and animation?

Shtirlitz [24]

Answer:

Multimedia avenue.

Explanation:

A file type is the standard used to store data such as pictures, texts, videos, and audios. All file types have unique file extension that determine which program to use to open a particular file and to access its data e.g pictures (jpeg, png), texts (txt, docx, rtf), videos (mp4, 3gp, avi), audios (mp3, acc).

Sometimes, computer users make the mistake of opening files with the wrong software application or program, this often leads to an error due to the incompatibility of the software application with the particular file.

Basically, all software applications are designed and developed for use with specific file extensions or formats and as such, when used to open a file it isn't developed for, it result in an error.

A multimedia avenue refers to a channel that is designed and developed to accept, utilize and combine various file formats such as audio, video, text, animation effects, etc. A common example of a multimedia avenue is Microsoft PowerPoint software.

Hence, the multimedia avenue may utilize video streaming, audio narration, print designs and animation.

HELLLP

mojhsa [17]

Explanation:

The output of this program is 5 7, because the first time bruce is printed, his value is 5, and the second time, his value is 7. The comma at the end of the first print statement suppresses the newline after the output, which is why both outputs appear on the same line.

Here is what multiple assignment looks like in a state diagram:

With multiple assignment it is especially important to distinguish between an assignment operation and a statement of equality. Because Python uses the equal sign (=) for assignment, it is tempting to interpret a statement like a = b as a statement of equality. It is not!

First, equality is symmetric and assignment is not. For example, in mathematics, if a = 7 then 7 = a. But in Python, the statement a = 7 is legal and 7 = a is not.

Furthermore, in mathematics, a statement of equality is always true. If a = b now, then a will always equal b. In Python, an assignment statement can make two variables equal, but they don’t have to stay that way:

a = 5

You have to write a program that will read a number followed by a series of bit operations from a file and perform the given ope

tatuchka [14]

The program what will read a number followed by a series of bit operations from file and perform the given operations sequentially on the number is given below.

<h3>What is an operation in computer science?</h3>

An operation, in mathematics and computer programming, is an action that is carried out to accomplish a given task.

There are five basic types of computer operations:

Inputting,
processing,
outputting,
storing, and
controlling.

<h3>What is the requested program above?</h3>

#include <stdio.h>

#include <fcntl.h>

int main(int argc, char *argv[])

{

int number, n, v, temp;

char line[25], fun[10];

FILE *f = fopen(argv[1], "r");

fgets(line, 24, f);

sscanf(line, "%d", &number); //reading the number

while( fgets(line, 24, f) )

{

sscanf(line, "%s %d %d", fun, &n, &v); //reading the commands

switch(fun[0]) //checking which command to run

{

case 'g': temp = 1;

temp = temp<<n; //shifting for getting that bit

printf("%d\n",(number&temp)&&1);

break;

case 's': temp = 1;

temp = temp<<n; //shifting for setting that bit

if(!v)

{

temp = ~temp;

number = number & temp;

}

else

{

number = number | temp;

}

printf("%d\n",number);

break;

case 'c': temp = 1;

temp = temp<<n; //shifting for complimenting that bit

number = number ^ temp; //xor to complement that bit

printf("%d\n",number);

break;

default:printf("not defined");

}

return 0;

}

Execution and Output:

terminal-> $ gcc -o first first.c

terminal-> $ ./first file1.txt
