Lubov Fominskaja [6]
<h2>Answer:</h2>

The number of possible arrangements is : 120

<h2>Step-by-step explanation:</h2>

We know that in order to find the different arrangements which are possible we need to use the method of permutation.

The arrangement of a given word is calculated as the ratio of the factorial of number of letters to the product of factorial of numbers the number of times each letter is repeating.

The word is given to be:

                    ALASKA

There are a total of 6 letters in the given word

Out of which a letter "A" is  repeating  3 times.

Hence, the number of arrangements possible are:

        =\dfrac{6!}{3!}\\\\\\=\dfrac{6\times 5\times 4\times 3!}{3!}\\\\\\=6\times 5\times 4\\\\\\=120

What percent of 75 is 40
9966 [12]

The answer is: " 53 \frac{1}{3} % " .

__________________________________________

→ " 53 \frac{1}{3} % " of 75 is "40" .

__________________________________________

Explanation:

To solve:

\frac{x}{100} * 75 = 40 ;

→ Rewrite as:

\frac{x}{100} * \frac{75}{1} = 40 ;

→ The "100" cancels to "4" ; and the "75" cancels to "3" ;

→ {since: "{100 ÷ 25 = 4}" ; and since: "{75 ÷ 25 = 3"} ;

→ So; we rewrite the problem as:

→ \frac{x}{4} * \frac{3}{1} = 40 ;

→ which is:

\frac{x}{4} * 3 = 40 ;

→ Divide each side of the equation by "3" ;

\frac{x}{4} * 3 ÷ 3 = 40 ÷ 3 ;

to get:

→ \frac{x}{4} = \frac{40}{3} ;

Now, cross-multiply:

→ 3x = (4)*(40) ;

→ 3x = 160 ;

Divide each side of the equation by "3" ;

to isolate "x" on one side of the equation; & to solve for "x" ;

→ 3x / 3 = 160 / 3 ;

to get:

→ x = 53 \frac{1}{3} .
