A man is distributing his coin collection with 35 coins to his five grandchildren. How many ways are there to distribute the coi

Musya8 [376]

Answer:

a) $82251$

b) $2.91038 \cdot 10^{24}$

c) $1$

d) $3.17746\cdot 10^{21}$

Step-by-step explanation:

a) If the coins are all the same, we have a combination of 35 identical coins in 5 persons.

The amount of combinations is

$\binom{n+r-1}{r-1}=\binom{35+5-1}{5-1}=\binom{39}{4}=\frac{39!}{4!35!} =82251$

being n the number of coins and r the number of grandchildren.

b) If the coins are different, the number of combinations can be calculated as:

$r^n=5^{35}=2.91038 \cdot 10^{24}$

c) If the coins are all the same, and each grandchild gets the same number of coins, there is only one combination for that (everyone gets 35/5=7 coins)

d) If the coins are all distinct, but each of the grandchildren get the same numer of coins, the expression to calculate this is:

$\frac{n!}{(n/r)!^r} =\frac{35!}{(35/5)!^5}=\frac{35!}{7!^5}=\frac{1.03331\cdot 10^{40}}{3.25202\cdot 10^{18}} =3.17746\cdot 10^{21}$

Find the measure of angle x in the figure below:

Sav [38]

Answer:

70 degrees

Step-by-step explanation:

The angle opposite x and x itself are vertical angles, meaning that they have the same angle measure. Since the sum of the interior angles of a triangle is 180 degrees:

x+55+55=180

x+110=180

x=180-110=70

Hope this helps!

Answer:

Step-by-step explanation:

(8-5)/(1-0) = 3/1 = 3

y - 5 = 3(x -0)

y -5 = 3x - 0

y = 3x + 5
