what is the decimal sign-and-magnitude value of the 8-bit number represented in 2's complement by 11010011?

Answers

Answer 1
Answer:

Answer:

-45.

Step-by-step explanation:

The decimal value is negative because the first digit is a '1'.

11010011

 First we subtract 1 :

11010011

           -1

11010010

Now we replace each 1 by 0 and 0 by 1:

= 00101101

In decimal this is - (1 + 2^2 + 2*3 + 2^5)

= -45.

Which expressions are equivalent to when x0? Check all that apply.

Answers

we have that

((x+4))/(3) / (6)/(x) = (x*(x+4))/(3*6) \n \n = (( x^(2) +4x))/(18)

therefore

case a) 
((x+4))/(3) * (x)/(6)
Is equivalent

case b) 
(6)/(x) * ((x+4))/(3)
Is not equivalent

case c) 
(x)/(6) * ((x+4))/(3)
Is  equivalent

case d) 
((2 x^(2) +4x))/(6)
Is not equivalent

case e) 
((2 x^(2) +4x))/(18)
Is equivalent

Hence

the answer is

((x+4))/(3) * (x)/(6)

(x)/(6) * ((x+4))/(3)

((2 x^(2) +4x))/(18)

Answer:

The correct representation of the expression are:

  •      (x+4)/(3)((x)/(6))
  •     ((x)/(6))(x+4)/(3)
  •     (x^2+4x)/(18)

Step-by-step explanation:

We are given an algebraic expression as:

        (x+4)/(3)÷(6)/(x)

This expression could also be written as:

=((x+4)/(3))/((6)/(x))

We know that any expression of the form:

((a)/(b))/((c)/(d)) is given by:

((a)/(b))/((c)/(d))=(a* d)/(b* c)}

Hence, we get the given expression as:

=((x+4)/(3))/((6)/(x))=((x+4)* x)/(3* 6)\n\n=(x+4)/(3)* (x)/(6)

Also, on solving we get:

=((x+4)/(3))/((6)/(x))=(x^2+4x)/(18)

Doctors use the term maximum heart rate (MHR) when referring to the quantity found by starting with 220 beats per minute and subtracting 1 beat per minute for each year of a
person’s age. Doctors recommend exercising 3 or 4 times each week for at least 20 minutes
with your heart rate increased from its resting heart rate (RHR) to its training heart rate
(THR), where THR = RHR + .65(MHR – RHR)
Which of the following is closest to the THR of a 43-year-old person whose RHR is 54 beats
per minute?
A. 197
B. 169
C. 162
D. 134
E. 80

Answers

THR = RHR + 0.65(MHR - RHR)
For a 43 year old person, MHR = 220 - 43 = 177

THR = 54 + 0.65(177 - 54) = 54 + 0.65(123) = 54 + 79.95 = 133.95 ≈ 134.
