Consider a computer that uses 6 bits to represent integers: 1 bit for the sign and 5 bits for the actual number. What's the largest positive integer it can represent?

Answers

Answer:

31

Step-by-step explanation:

Therefore, range of 5 bit unsigned binary number is from 0 to (25-1) which is equal from minimum value 0 (i.e., 00000) to maximum value 31 (i.e., 11111).

The largest positive integer will be 31.

It is given that a computer has uses 6 bits to represent integers out of which 1 bit is for sign and 5 bits is the actual number.

We have to find out the largest positive integer it can represent.

What do you mean by the binary number system ?

In the Binary number system there are only two numerals , represented by 0 and 1, and its digits are often referred to as bits.

As per the question ;

A computer has uses 6 bits to represent integers.

Max number = [tex]2^{n}[/tex]

and the largest possible number we could represent using n no. of bits =   [tex]2^{n}[/tex] - 1

Here if ;

n = 6 bits

So ,

Max number = [tex]2^{6}[/tex] = 64

and

The largest number = [tex]2^{6}[/tex] - 1

= 64 - 1

= 63

It is also given that ;

Out of 6 bits , 1 bit is for sign and 5 bits is the actual number ;

So ;

for n = 5 bits

The largest positive integer will be ;

= [tex]2^{5}[/tex] - 1

= 31

Thus , the largest positive integer will be 31.

The Candy Factory has 30 pounds of fudge. The fudge is sold in ​2 1/5 pound boxes. Janie cuts the fudge, and fills as many boxes as possible.

What fractional part of a box remains after filling as many boxes as possible?

Answers

Answer:

13 7/11

Step-by-step explanation:

DIVIDE

The  fractional part of a box remains after filling as many boxes as possible is 7/11

Given the following:

Amount of pounds of candy factory = 30 poundsIf the fudge is sold in ​2 1/5 pound boxes., the number of boxes that can be filled is expressed as:

Number of boxes filled = 30 ÷ 2 1/5

Number of boxes filled = 30 * 5/11

Number of boxes filled = 150/11

Number of boxes filled = 13 7/11

Hence the  fractional part of a box remains after filling as many boxes as possible is 7/11

B. How many laps per minute is that? (1 point)
C. How long would it take Lin to run 15 laps at the same rate? (1 point)

Answers

Answer:

Number of minutes per lap = 2.25 minute

Number of laps = 4

Time taken = 9 min

Computation:

Number of minutes per lap = 9 / 4

Number of minutes per lap = 2.25 minute

Number of lap per minute = 4 / 9

Number of lap per minute = 0.444 lap (Approx)

Time taken for 15 lap = 15 x 2.25

Time taken for 15 lap = 33.75 minutes

a new theater is being built for the city ballet. the balcony has 150 seats. the floor has 15 rows with x seats in each row. the number of people in the theater must be under 360 to meet fire safety regulations. what is the solution of thus inequality, and what is its meeting?

answers in the picture ​

Answers

a is correct because it has to be under 360 so the 360 is the greatest it can go

The solution is Option A.

15x + 150 < 360 . The new theater must have fewer than 14 seats in each row on the floor to meet fire safety regulations

The inequality equation is x < 14

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Let the total number of people in the theater be = 360 people

The number of seats in the balcony = 150

Let the number of seats be x

The number of rows = 15

The number of seats in 15 rows = 15x

So , the inequality equation is

Number of seats in 15 rows + number of seats in the balcony < total number of people in the theater

Substituting the values in the equation , we get

15x + 150 < 360

On simplifying the equation , we get

Subtracting 150 on both sides of the equation , we get

15x < 210

Divide by 15 on both sides of the equation , we get

x < 14

Therefore , the value of x is less than 14

Hence , the new theater must have less than 14 seats in each row

​​ B. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and

b b is the y-intercept. y = m x + b y = m x +

b Using the slope-intercept form, the slope is 0. m = 0

A. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and

b b is the y-intercept. y = m x + b y = m x +
