Answer:

D) They are coded.

Explanation:

Java comments are notes in a Java code file that are ignored by the compiler and runtime engine. They are used to annotate the code in order to clarify its design and purpose. You can add an unlimited number of comments to a Java file, but there are some "best practices" to follow when using comments.

Two machines can finish a job in StartFraction 20 Over 9 EndFraction hours. Working alone, one machine would take one hour long

Alborosie

Answer

5 hours

Explanation

The two working together can finish a job in

$\frac{20}{9} \: hours$

Also, working alone, one machine would take one hour longer than the other to complete the same job.

Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.

Their combined rate in terms of x is

$\frac{1}{x} + \frac{1}{x - 1}$

This should be equal to 20/9 hours.

$\frac{1}{x} + \frac{1}{x - 1} = \frac{9}{20}$

Multiply through by;

$20x(x - 1) \times \frac{1}{x} +20x(x - 1) \times \frac{1}{x - 1} = 20x(x - 1) \times \frac{9}{0}$

$20(x - 1) +20x = 9x(x - 1)$

$20x - 20+20x = 9{x}^{2} - 9x$

$9{x}^{2} - 9x - 20x - 20x + 20= 0$

$9{x}^{2} - 49x + 20= 0$

Factor to get:

$(9x - 4)(x - 5) = 0$

$x = \frac{4}{9} \: or \: x = 5$

It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.

Therefore the slower finish in 5 hours.

How is binary used in pixels and in sound?

FinnZ [79.3K]

Answer:

Sound needs to be converted into binary for computers to be able to process it. To do this, sound is captured - usually by a microphone - and then converted into a digital signal. The samples can then be converted to binary. They will be recorded to the nearest whole number.

Write a python application that allows a user to enter any number of student test scores until the user enters 999. If the score

Kryger [21]

Answer:

This program is as follows

total = 0; count = 0

testscore = int(input("Score: "))

while testscore != 999:

if testscore < 0 or testscore > 100:

print("Out of range")

else:

total+=testscore

count+=1

testscore= int(input("Score: "))

print(count,"scores entered")

print("Arithmetic Average:",total/count)

Explanation:

This initializes total and count to 0

total = 0; count = 0

This gets input for score

testscore = int(input("Score: "))

The following iteration stop when 999 is entered

while testscore != 999:

This prints out of range for scores outside 0 - 100

if testscore < 0 or testscore > 100:

print("Out of range")

Otherwise

else:

The total score is calculated

total+=testscore

The number of score is calculated

count+=1

Get another input

testscore = int(input("Score: "))

The number of score is printed

print(count,"scores entered")

The average of score is printed

print("Arithmetic Average:",total/count)
