There are nine empty seats in a theater, and six customers need to find places to sit. How many different ways can these six sea

dybincka [34]

Answer: 60480

Step-by-step explanation:

Given : The number of empty seats in a theater = 9

The number of customers need to find places to sit =6

Since order matters here, so we use permutations

The permutations of n things taking r at a time is given by :-

$^nP_r=\dfrac{n!}{(n-r)!}$

Then, the number of ways to arrange 6 seat in 9 seats :-

$^9P_6=\dfrac{9!}{(9-6)!}=\dfrac{9\times8\times7\times6\times5\times4\times3!}{3!}\\\\=60480$

Hence, the number of ways to arrange 6 seat in 9 seats = 60480

The owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway. If s

navik [9.2K]

Answer:

Step-by-step explanation:

Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.

Fencing is used for 2times length and 1 width if highway side is taken as width

So we have 2l+w = 2900

Or w = 2900-2l

Area of the rectangular region = lw

$A(l) = l(2900-2l) = 2900l-2l^2\\$

Use derivative test to find the maximum

$A'(l) = 2900-4l\\A"(l) = -4$

So maximum when I derivative =0

i.e when $l =\frac{2900}{4} =725$

Largest area = A(725)

= $725(2900-2*725)\\= 1051250$

1051250 sqm is area maximum

algol13

Answer:

8x = 104

Since we are trying to distribute it evenly, we divide 104 by 8 to get 13 pieces of candy per child.

The equation is saying 8 kids times <em>x</em> amount of candy per kid is equal to a total amount of 104 pieces of candy.
