Colin & Brian share a lottery win of £2100 in the ratio 4 : 1. Colin then shares his part between himself, his wife & th

Paraphin [41]

Answer:

His wife gets $336 more than his son.

Step-by-step explanation:

Colin and Brian:

Ratio of 4:1.

So Colin gets $\frac{4}{4+1} = \frac{4}{5}$ of the prize.

$\frac{4*2100}{5} = 1680$

Colin got $1680. Dividing between himself, his wife and their son:

Ratio of 2:5:3.

So Colin gets $\frac{2}{2+3+5} = \frac{2}{10}$ , his wife gets $\frac{5}{2+3+5} = \frac{5}{10}$ and his son gets $\frac{3}{2+3+5} = \frac{3}{10}$

Wife:

$\frac{5*1680}{10} = 840$

His wife got $840.

Son:

$\frac{3*1680}{10} = 504$

His son got $504.

How much more does his wife get over their son?

840 - 504 = 336

His wife gets $336 more than his son.

mixas84 [53]

The formula of combination is

$nCr= \frac{n!}{(n-r)!r!}$

We have $n=14$ and $r=10$

$14C10= \frac{14!}{(14-10)!10!} = 1001$

Hence, there are 1001 ways of arranging 10 records from 14 records

What (3×5^2)/(5)^2 equal? Plz answer fast and with work and I will give brainliest

balu736 [363]

Answer:

The answer is 3.

Step-by-step explanation:

Given that the Indices Law is,

${a}^{m} \div {a}^{n} = {a}^{m - n}$

${a}^{0} = 1$

So the expression is :

$3 \times {5}^{2} \div {5}^{2}$

$= 3 \times {5}^{2 - 2}$

$= 3 \times {5}^{0}$

$= 3 \times 1$

$= 3$
