What is the base 5 representation of the number 465^8
andreev551 [17]

Answer  

Option C : 2214(5)

Solution


The given number is 465 in base 8. To convert this number to base 5,we need to convert this number to base 10, then only we can compute the number in base 5


Step1 : Convert 465 to the base 8 to base 10


4 x 82=256


6 x 81=48


5 x 80=5


Adding 256 + 48+ 5 = 309(10)


Step2 : Convert 309(10) to base 5  

5 | 309  

5 | 61 |4


5 | 12 | 1


5 | 2  | 2


5 | 0  | 2



Therefore Answer = 2214(5 )

What is the measure of an interior angle of a regular 12-gon?
gavmur [86]

Answer:

The measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.                          

Step-by-step explanation:

We need to determine the measure of an interior angle of a regular 12-gon.

  • We know that the number of sides in a regular 12-gon = n = 12

Thus,

Using the formula to determine the measure of an interior angle of a regular 12-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 12

(12 - 2) × 180 = 12 × interior angle

10 × 180 = 12 × interior angle

Interior angle = (10 × 180) / 12

                      = 1800 / 12

                      = 150°

Therefore, the measure of an interior angle of a regular 12-gon is 150°.

Hence, option 'C' is correct.
