Answer:

Option A: print("The total is %0.5f" % total)

Explanation:

To ensure the value is rounded to a precision of 5 digits, we have to create a formatted string which is %0.5f. The .5 denotes five decimal places and f refers to float data type.

Next, we use the % operator again and followed with the variable total. The % is used as a string modulo operator that will interpolate the value held by the the variable total in the formatted string that we create previously. The interpolated value will be rounded to 5 decimal places. For example, if

total = 256.786789

The output will be 256.78679

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

The points a b c and d lie on a straight line ab:bd = 1:4

The points a b c and d lie on a straight line ab:bd = 1:4 are A line that extends to infinity on both sides and has no curves is called a straight line.AB:BC=3:4.

<h3>What do you call a straight line? </h3>

A line is simply an object in geometry denoted as an object with no width that extends on both sides. A straight line is just a line with no curves.

AC=AB+BC=3+4=7; AC:CD=2:1, i.e. AC=2; because we get 2 different lengths for AC, we change the given ratio AC:CD to an equivalent one with AC=7 .
As follows: AC:CD = 2 : 1 = 7 : 3.5 (multiply both sides by 3.5 ) Now we have AC:CD = 7 : 3.5 and AD = AC+CD= 7+3.5 = 10.5,, and the answer is: the ratio BC:AD = 4:10.5.
