Answer:

A B A NOR B

F F T

F T F

T F F

T T F

Step-by-step explanation:

The logical operator NOR produces a result that is the negation of the logical operator OR.

The truth table for the logical operator NOR can be obtained by the negation of the results of the truth table for the logical operator OR.

Let A and B be the the logical values (or inputs). The operator OR produces a value of true if and only if at least one operand is true. The truth table for OR is:

A B A OR B

F F F

F T T

T F T

T T T

So, the truth table for NOR is:

A B A NOR B

F F T

F T F

T F F

T T F

Notice that the negation of OR (which is NOR) is obtained by changing the F by T and the T by F in the column of the results.

This table can also be writen with 0 instead of False and 1 instead of True.

First Method:

Round $\frac{3}{5}$ to the closest integer, which is 1.

Round $\frac{3}{4}$ to the closest integer, which is also 1.

So 1 + 1 = 2.

Answer for method 1: 2

Second Method:

$\frac{3}{5}$ + $\frac{3}{4}$ = $\frac{3*4}{5*4} + \frac{3*5}{4*5} = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}$

$\frac{27}{20}$ is around 1

Answer for method 2: 1

The closest answer is 1.

A board that measures 3/4 feet long is cut into 6 equal pieces. What is the length of each piece?

shusha [124]

Answer:

See below:

Step-by-step explanation:

So we know that there is a $\frac{3}{4}$ feet long board and that it is split into 6 pieces.

With that information, we can split it by doing the following:

1. $\frac{3}{4} *\frac{1}{6}$

We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.

After doing that, we get our answer of $\frac{3}{24}=\frac{1}{8}$
