$\\ \qquad\quad\sf\longmapsto \dfrac{n!}{2!(n-2)!}=\dfrac{n!}{4!(n-4)!}$

$\\ \qquad\quad\sf\longmapsto 2=24(n-4)(n-3)$

$\\ \qquad\quad\sf\longmapsto 2=24\left\{n(n-3)-4(n-3)\right\}$

$\\ \qquad\quad\sf\longmapsto 2=24(n^2-3n-4n+12)$

Gary buys a 31/2 pound bag of cat food every 3 weeks.Gary feeds his cat the same amount of food each day.Write a numeric express

Ilya [14]

Answer:

$52\times \frac{7}{6}$

$60\frac{2}{3}\text{ pounds}$

Step-by-step explanation:

Given,

The total pounds eaten by cat in 3 weeks = $3\frac{1}{2}$ = $\frac{7}{2}$

∵ Each day the pounds of eaten is same,

⇒ Total pounds eaten in each week = $\frac{7}{6}$

∵ 1 year = 52 weeks,

So, the pounds eaten in 52 weeks or 1 year = 52 × pounds eaten in each week

= 52 × $\frac{7}{6}$

Which is the required expression,

By solving it,

The number of pounds eaten by cat in a year

$=\frac{364}{6}$

$=60\frac{2}{3}$

The breadth of a rectangular garden is 2/3 of its legth. If its perimeter is 40cm, find its dimensions.

Arisa [49]

Answer:

12; 8

Step-by-step explanation:

length-x

breadth-2/3x

2(x+2/3 x)=40

2×5/3x=40

10/3x=40

x=40÷10/3

x=40×3/10

x=12 (cm) length

2/3×12=8 (cm) breadth
