Answer:

$6\frac{3}{4}\ ft$

Step-by-step explanation:

we know that

To find out how long is Ms.Smith’s bulletin board, multiply Mrs . Porcelli’s bulletin board by 3

$2\frac{1}{4}(3)$

but first convert mixed number to an improper fraction

$2\frac{1}{4}\ ft=2+\frac{1}{4}=\frac{9}{4}\ ft$

substitute

$\frac{9}{4}(3)=\frac{27}{4}\ ft$

convert to mixed number

$\frac{27}{4}\ ft=\frac{24}{4}+\frac{3}{4}=6\frac{3}{4}\ ft$

The diagram rerpesents responses to a survey that include statements p and q . Which statement is true?

BARSIC [14]

Answer:

C. The number of responces $p\vee q$ is also 46

Step-by-step explanation:

Note that:

$p\wedge q$ means both p and q must hold;
$p\vee q$ means either p or q must hold.

From the diagram,

the number of responses $p\wedge q$ is 46;
the number of responces $p\vee q$ is also 46;
the number of responces $p\setminus q$ is 0;
the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C
