nadya68 [22]3 years ago
5 0

Answer:

B. 11110111

Explanation:

Binary representation of number 9 = 00001001

Binary representation of -9 would involve calculating the twos complement representation of 00001001

First we compute the ones complement of this number by reversing the bits.

00001001 => 11110110

Next we calculate the twos complement representation by adding 1 to the ones complement.

11110110+1 = 11110111

So the final representation is 11110111.

Laws differ from theories because laws do not provide
AveGali [126]
Laws differ from theories because laws do not provide an explanation for how things work or could possibly work. A law describes what happens or needs to happen under certain conditions. A law can predict what will happen as long as those conditions are met. <span>For the purposes of this discussion, a "law" is a rule that has been formalised by repeated testing. It is also a generalisation. A theory, on the other hand, is an explanation for an observation that is supported by a large body of evidence. </span>

Given:

Amount of carbohydrate = 58 gram

Amount of protein = 12 gram

Amount of fat = 5 gram

Find:

Total amount of calories

Computation:

1 gram protein = 4 calories

1 gram carbohydrate = 4 calories

1 gram fat = 9 calories

Total amount of calories = (58)(4) + (12)(4) + (5)(9)

Total amount of calories = 232 +48 + 45

Total amount of calories = 325

  • Requires skilled person who can develop and design the software to be used again.The creating and designing of new software design is comparatively easy but making the system reusable requires someone who has more designing skill who will be highly paid for the work
  • Cost of writing and reading of the software can also be considered as the economical challenge as the reused system created is to be studied by some other organization members or sources not familiar with the functioning. .
