How many distinct arrangements can you make using the letters in the word experiment

1 answer:

8 0

E x p e r i m e n t

Total number of letters = 10

Repeated letters = 3 e

Total arrangement from the 10 letters = 10!

Because of the repeated letters = 10! / 3!

   = (10 × 9 × 8 × 7× 6 × 5 × 4 × 3!) / 3!

   = 10 × 9 × 8 × 7× 6 × 5 × 4

   = 604800

604800 distinct arrangements.

The costs of 5 similar digital cameras and 3 similar video cameras is $3,213. Each video camera costs 4 times as much as each di

mariarad [96]

Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)

Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189

Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756

Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945

Find two numbers whose sum is 64 and whose difference is 42

vovangra [49]

These numbers are "a" and "b".
Sum is 64, so a+b=64
Difference is 42 so a-b=42
So you've got:
$+\begin{cases} a+b=64 \\ a-b=42\end{cases} \\ \overline{, \quad2a \quad \ = \ 106} \qquad /:2 \\ a=53$
When a+b=64 and a=53 you've got:
53+b=64
b=11

So these numbers is 53 and 11.
