Answer:

12,000,000 bytes.

Explanation:

If we want to store an uncompressed binary image, assuming that we will use 256 different levels to represent all tones in a monochromatic image, each pixel will be stored as an 8-bit sample, i.e. one byte per pixel.

The complete image will have 4000 pixels wide by 3000 pixels height, so an entire image will need 3000*4000= 12,000,000 pixels.

As we will use 8 bits= 1 Byte per pixel, we will need to store 12,000, 000 bytes for a complete uncompressed monochromatic (white & black) image.

Which of the following is an example of a Boolean operator?

miv72 [106K]

Answer:

C. But

Explanation:

Boolean operators are the operators that may have only two outputs which are True/False, On/Off and 1/0.

"But" can also be the example of Boolean operator. It is used in the meaning of "except" or "other than".

In Boolean operators "But" can be used as "AND" operator.

for example

I am busy but I will go.

In above example but is used as and which is combining two oposite statements. as

I am busy and I will go.

Both statement oppose each other, so to make sense in English "But" is used.

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.

Which type of memory helps in reading as well as writing data?

Anuta_ua [19.1K]

The read-write type of memory helps in reading as well as writing data. This computer memory is used by users to continually update the data (to access (read from) or alter (write to) ) that is held on hardware storage devices. Internal or external hard disk drives, rewritable CDs or small flash drives can be all physical setups of read-write memory.
