You are standing in one big palace where a king and his 5 queens stay. Each queen has 5 rooms. In each room there are 5 big cats
Paladinen [302]
(5+1+1)*2 + 5*5*5*(1+5)*4 = 3014
Rooms = 5*5 = 25
Cats per room = 5 + 5*5 = 30
All cats legs = 25*30*4 = 3000
All humans = 1+1+5 = 7
All humans legs = 7*2 = 14
All legs = 3000 + 14 = 3014

Free_Kalibri [48]

Answer:

(a) 1,902,231,808,400

(b) 84

(c) 20

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

{n\choose k}=\frac{n!}{k!\cdot(n-k)!}

(a)

Compute the number of ways to select 9 applicants from 100 as follows:

{100\choose 9}=\frac{100!}{9!\cdot(100-9)!}

        =\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400

(b)

Compute the number of ways to select 6 people from 9 as follows:

{9\choose 6}=\frac{9!}{6!\cdot(9-6)!}

        =\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84

(c)

Compute the number of ways to select top 3 candidates from 6 as follows:

{6\choose 3}=\frac{6!}{3!\cdot(6-3)!}

        =\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20

A gardener is planting two types of trees:
liq [111]

Answer:

10 years

Step-by-step explanation:

let they become of same height after t years

3ft=36 inches

hence

height of A

Ha=36+21t

8ft=96 inches

height of B

Hb = 96+15t

as Ha =Hb

36+21t =96+15t

21t-15t =96-36

6t=60

t=60/6

t= 10 years
