Answer:

False

Explanation:

IPv4 address are composed of four octets (8 bit numbers), ranging from 0.0.0.0 to 255.255.255.255

All those 32 bits, in decimal notation, can form a total of

$2^{32} = 4,294,967,296$ different addresses.

Being more than 4 billion addresses and ignoring that some addressesare reserved for special uses, even present human population almost doubles that number.

So it is safe to state that IPv4 addresses is not enough to give every blade of grass its own IP.

Input two numbers and print their sum products difference division and remainder

likoan [24]

$\tt n1=int(input("Enter\: first\:no:"))$

$\tt n2=int(input("Enter\: second\:no:"))$

$\tt sum=n1+n2$

$\tt diff=n1-n2$

$\tt pdt=n1*n2$

$\tt div=n1//n2$

$\tt rem=n1\%n2$

$\tt print("Sum=",sum)$

$\tt print("Difference=",diff)$

$\tt print("Product=",pdt)$

$\tt print ("Division=",div)$

$\tt print("Remainder=",rem)$

Output:-

Enter first no:4

Enter second no:3

Sum=7

Difference=1

Product=12

Division=1

Remainder=1

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.

The concept of algorithm ____, is one in which you can observe an algorithm being executed and watch as data values are dynamica

Yakvenalex [24]

The answer to this question would be algorithm animation.

Since the algorithm is animate, then you will be able to watch it works. Watching the algorithm executed can give you much information, what the algorithm does and how the algorithm does it.
Normally you will not be able to do this since the algorithm only do what it needs to do without reporting the detail to you
