What is the value of n in the equation (2n + 4) + 6 = -9 + 4(2n + 1)?
alexandr402 [8]

Answer:

n=2.5

Step-by-step explanation:

  • (2n + 4) + 6 = -9 + 4(2n + 1)
  • 2n+10=-9+8n+4
  • 2n+10=8n-5
  • 8n-2n= 10+5
  • 6n=15
  • n=15/6
  • n=2.5

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.

. A pitcher’s mound on a women’s softball field is 43 feet from home plate and the distance between the bases is 60 feet. How fa
butalik [34]

Answer:

42.43 ft

Step-by-step explanation:

Please find attached an image of the softball pitch

h² = p² + f² -2x p×f×cos45

h² = 43² + 60² - 2x (43)(60) x 0.7071

h² = 1849 +  3600 - 3648.636

h² = 1800.364

h = √1800.364

h = 42.43 feet
