alexgriva [62]

Answer:

The number of ways is $\left n} \atop {}} \right. P_r = 336$

Step-by-step explanation:

From the question we are told that

The number of tickets are $n = 8$

The number of finalist are $r =3$

Generally the number of way by which this winners can be drawn and arrange in the order of $1^{st} , \ 2nd , \ 3rd$ is mathematically represented as

$\left n} \atop {}} \right. P_r = \frac{n\ !}{(n-r) !}$

substituting values

$\left n} \atop {}} \right. P_r = \frac{ 8!}{(8-3) !}$

$\left n} \atop {}} \right. P_r = \frac{ 8* 7*6*5*4*3*2*1}{ 5*4*3*2*1}$

$\left n} \atop {}} \right. P_r = 336$

How many litres of fuel will a car use to travel 450 km if its fuel consumption is 6,8 km/l?

valentina_108 [34]

Step-by-step explanation:

are you sure the fuel consumption is given by 6,8 km/l ?

normally it is given by l/100km.

but ok, let's assume this is correct.

it would mean the car can drive 6,8 km with every liter of fuel in the tank.

how many liters will the car need to go 450 km ?

well, as many liters as 6,8 fits into 450 :

450/6,8 = 66.17647059... liters

this is not a very fuel efficient car ...
