Answer:
(311)₁₀ = (137)₁₆
Explanation:
To convert a base 10 or decimal number to base 16 or hexadecimal number we have to repeatedly divide the decimal number by 16 until it becomes zero and write the remainders in the reverse direction of obtaining them.
311/16 = 19 remainder=7
19/16=1 remainder = 3
1/16 remainder = 1
Writing the remainder in the reverse direction that is (137)₁₆.
Hence the answer is 137.
Answer:
348 + 395 = 743
Hence, together they have 743 pennies and not 653 pennies. And we cannot perform the rounding, as that is the case when we have the decimal number or the float number. Only then we have the digits after the decimal. And if it's more than 5, we add 1 to the previous or else leave the number as it is. And we go on performing from right to left, and till the number of decimal places, we need to round off. However, here its purely an integer, and hence we cannot round off, as that will result in a significant loss, and which is not acceptable. However, if we want to round off before decimal places as well, then in that case 743 will be $7s, and 653 pennies will be 6+1= $7s, and if this level of loss is acceptable then we can assume that they have the same sum of money. However, here the answer is given in pennies, and hence this is not the case. And hence the answer given in the question is not correct.
Explanation:
The answer is self-explanatory. And since both are numbers, rounding is not required(as explained in the answer section), as it is required in case of decimal and float(as explained in the answer section). And as explained in the answer section, if we can tolerate very heavy loss, then the numbers as well can be rounded off as explained in the answer section. But that is not the case here, as the answer is given in pennies.
Because to prevent MITD (Man in the middle is a man that in the middle of the network. For example: You are sending a text, the man in the middle or in the modem will receive the text and can edit it and send it to the receiver, or the man will put the virus in...) and to prevent server snooping
You have to think about, what could happen to you if you shared this information.
Hope this helped!
