Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are shown) [1.5 x 4 = 6 marks]
katen-ka-za [31]

Answer:

i. 10210212

ii. 100 101 001 in BASE 2

iii. 46.4631

iv. 12.453125

Explanation:

i. Converting to base 10 we get

=  10 x 162 + 13 x 161 + 9 x 160 = 2777

Converting to base 10 we get  =

2777/3 = 925 with remainder 2

925/3 = 308 with remainder 1

308/3 = 102 with remainder 2

102/3 = 34 with remainder 0

34/3 = 11 with remainder 1

11/3 = 3 with remainder 2

3/3 = 1 with remainder 0

1/3 = 0 with remainder 1

Hence the Answer is 10210212

ii. = Octal is taken in pair of 3 bits , Writing binary of each number in 3 bits we get  = 100 101 001 in BASE 2

iii. = 1 x 52 + 2 x 51 + 3 x 50 + 3 x 5-1   = 38.6 in decimal

Converting to Octal we get

38 /8 = 4 with remainder 6

4 /8 = 0 with remainder 4

.6 x 8 =  4.8

.8 x 8 = 6.4

46.4631

iv. = 1x 81 + 4 x 80 + 3 x 8-1 + 5 x 8-2   = 12.453125

Which of these are correctly formatted Python dictionaries? Check all that apply. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’
Advocard [28]

Answer:

A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}

Explanation:

Since <em>python does not use type when declaring a variable</em>, you must make sure you make your variables correctly or else it won't compile correctly. Lists use braces[]; Strings use quotes, "" or ''; Integers are just declared with a number(s); Dictionaries use brackets{} and inside are <u>attributes of something</u>. For instance, you can use dictionaries to describe ages, {'"Bryan": 6, "Alex": 13, etc.} <u>Sort of like a json file</u>. Dictionaries also tend to use <u>uppercase letters</u> when describing something. The only answer that has all the attributes correct is A. dict = {‘Name’: ‘Matthew’, ‘Age’: 14, ‘School’: ‘ABC School’}

hope i helped :D

The volume of a sphere is 4/3πr3, where π has the value of "pi". Write a function called print_volume (r) that takes an argument
Marizza181 [45]

Answer:

In Python:

def print_volume (r):

   volume = 4/3 * 3.142*r**3

   print(volume)

print_volume(7)

print_volume(14)

print_volume(22)

Explanation:

This defines the function and takes radius r as the parameter

def print_volume (r):

This calculates the volume

   volume = 4/3 * 3.142*r**3

This prints the volume

   print(volume)

The next three lines call the function with different values

<em>print_volume(7)</em>

<em>print_volume(14)</em>

<em>print_volume(22)</em>
