Convert the following:<br> 110110two to base ten<br> 25ten to base two<br>​
blagie [28]

Answer:

  • 110110 in base 2 when converted in base 10 will be equal to 54
  • 25 in base 10 is equal to 1001 base 2

Step-by-step explanation:

Part 1: 110110two to base ten

For conversion from base 2 to base 10 we multiply each digits of given number with powers of 2

So

=1*2^5 + 1 * 2^4 + 0 * 2^3 + 1 *2^2 + 1* 2^1 + 0*2^0\\ =1*32+ 1* 16 + 0 + 1*4 + 1*2 +0\\ =32 + 16 +4 + 2\\ = 54

So 110110two when converted in base 10 will be equal to 54

Part 2: 25ten to base two

For conversion from base 10 to base 2 we will divide the given number with 2 repeatedly and store the remainders until the quotient comes 1. The solution is as follows:

25/2 = 12     remainder 1

12/2 = 6       remainder 0

6/2 = 3        remainder 0

3/2 = 1         remainder 1

Now the remainders will be written in inverse order as:

=1001 base 2

So 25 in base 10 is equal to 1001 base 2

I hope it will help you!

What’s the value of x
skelet666 [1.2K]

Answer:

Step-by-step explanation:

You are given an angle, the adjacent side to the angle, and need the hypotenuse of the triangle.  Use Cos x  to find the missing side.

Cos α = (adjacent side)/(hypotenuse)

Cos 45 = 10/x

    x(Cos 45) = 10       (multiply both sides by x to get rid of the fraction)

       x = 10/(Cos 45)    (divide both sides by Cos 45 to isolate x

  Cos 45 = (√2)/2   so we have...

        x = 10/[(√2)/2]  

now simplify...

    x = 10*(2/√2)

       x =  20/√2

           x = (20√2)/[(√2)(√2)

               x = (20√2)/2

                      x = 10√2

                or x = 14.1421 if you use a calculator
