there are 6 times as many ways to arrange the letters in the word "sleeplessness" as there are to arrange the letters in the wor

EastWind [94]

Using arrangements of words, it is found that the statement is true.

------------------

Suppose a word has n letters.
Considering that m of these letters are repeating, each $n_1,n_2,...,n_m$ times.
The number of distinct ways the word can be arranged is given by:

$N = \frac{n!}{n_1\times n_2 \times ... n_m}$

------------------

The word "sleeplessness" has 13 letters.
s repeats 5 times.
e repeats 4 times.
l repeats 2 times.

Thus, the number of ways to arrange the letters is given by:

$N_1 = \frac{13!}{5!4!2!}$

------------------

The word "senselessness" has 13 letters.
s repeats 6 times.
e repeats 4 times.
n repeats 2 times.

Thus, the number of ways to arrange the letters is given by:

$N_2 = \frac{13!}{6!4!2!}$

------------------

Finding the ratio of $N_2$ to $N_1$ :

$\frac{N_2}{N_1} = \frac{\frac{13!}{5!4!2!}}{\frac{13!}{6!4!2!}} = \frac{13!}{5!4!2!} \times \frac{6!4!2!}{13!} = \frac{6!}{5!} = 6$

Thus, since the ratio is 6, the statement is true.

Solve for x in the equation 3x + 8 = x - 12.

Yuliya22 [10]

Answer:

x = -10

Step-by-step explanation:

Combine like terms and solve for x

3x + 8 = x - 12

3x= x - 20

2x = -20

x = -10

Lucy had math and reading homework tonight. Lucy can solve each math problem in 5 minutes and she can read each page in 2.5 minu

drek231 [11]

Answer:

$x=18,y=6$ , graph is there for reference.

Step-by-step explanation:

Given,

$x$ is the number of math problem Lucy solved.

$y$ is the number of pages she read.

She can do each math problem in $5$ minutes, therefore she can solve $x$ number of questions into $5 \times x=5x$ minutes.

She can read each page in $2.5$ minutes, therefore she can read $y$ pages in 2.5y minutes.

As per given detail,

$5x+2.5y=105$ equation 1.

And,

It is given that number of math problems Lucy solved is 3 times the number of pages she read.

$x=3y$ equation 2.

We need to find $x$ and $y$ intercept of each of the equation to graph them.

For $x-intercept$ put y=0

We will get $x=\frac{105}{5} =21$

Thus the point is $(21,0)$

Let us find $y-intercept$ by assuming $x=0$

we get $y=\frac{105}{2.5} =42$

Thus the point is $(42,0)$

Join these two points.

Similarly considering the other equation $x=3y$

Here x-intercept would be at $y=0$

We will get $x=0$

Thus the point is $(0,0)$

Let us assume on more point, say $x=30$ , we get $y=10$

Thus the point is $(30,10)$

Join these two points.

We will get a point of intersection at $(18,6)$

Thus $x=18$ and $y=6$
