What is the difference between decimal and binary numbering systems give examples of when you would use each?
vaieri [72.5K]

The difference between decimal and binary system are-

  • The base-10 system, often known as the decimal system, is the oldest and most widely used system of numbers.
  • The binary number system, often known as base 2, is used by computers.
<h3>What is decimal system?</h3>

Our daily use of numbers is based on a decimal number system, which uses 10 digits. A number system in mathematics is thought of as the use of digits or symbols to represent numbers.

  • The binary number system, the decimal number system, the octal number system, and the hexadecimal number system are the four primary varieties of the number system.
  • Given that it was challenging to multiply & divide big numbers by hand in earlier civilizations, this decimal system system is sometimes called as the Hindu-Arabic and Arabic number system.
<h3>What is binary system?</h3>

The base-2 number system is the binary system. That implies that it solely use the digits 0 and 1. The 1 one location is moved to its left into the 2s place when adding one to one, and a 0 is placed in the ones place, yielding the number 10. In such a base-10 system, 10 thus = 10. 10 = 2 in the base-2 system.

  • The place values in a base-2 system begin with ones and progress to twos, fours, then eights as one move to its left.
  • This is due to the base-2 system's foundation in powers of two.
  • A bit is the term for each binary digit.

Therefore, a binary number system only employs two different digits(0 and 1), whereas decimal number system includes ten different digits (ranging from 0 to 9).

If log a=3 log b-2 log c, find an expression for a that does not involve logarithms​
photoshop1234 [79]

Assuming that b>0 and c>0:

log(a)=3×log(b)-2×log(c)=

log(b³)-log(c²)=

log(b³/c²)

Hence a=b³/c²

Winnie wrote the following riddle.I am a number between 60 and 100.My ones digit is two less than my tens digit.I am a prime num
Kazeer [188]

Answer:

79

Step-by-step explanation:

60<xy<100

y -2 =x


if it is prime

y cannot be even

so y could be      1,3,5,7,9

x would then be 9,1,3,5,7

but to be between 60 and 100

x must be 7 or 9

so the number must be 79 or 57

57 is not prime so

the number is 79

2. A coordinate grid is used to make a map of the park. The location of the drinking fountain is (-4, 2) ; the location of the b
leva [86]

Answer:

(A) The distance from the drinking fountain to the bench is 4, and the distance from the bench to the center of the slide is 3 because if you add -4 and 0 you will get 4 and if you subtract 5 and 2 you will get 3.

(B) The type of triangle that is created is an obtuse triangle because when you connect the 3 locations it creates an obtuse triangle on the coordinate grid.

Step-by-step explanation:

I already explained in the answer. Hope this helps and gets you an 100%
