Inspecting Restaurants How many different ways can a city health department inspector visit restaurants in a city with restauran

tankabanditka [31]

Answer:

252 ways

Step-by-step explanation:

The missing details are:

$n = 10$ --- total restaurants

$r = 5$ --- restaurants to visit

Required

The number of ways to perform the visitation

The question is an illustration of combination;

So, we have:

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

This gives:

$^{10}C_5 = \frac{10!}{(10 - 5)!*5!}$

$^{10}C_5 = \frac{10!}{5!*5!}$

Expand

$^{10}C_5 = \frac{10*9*8*7*6*5!}{5!*5*4*3*2*1}$

Cancel out 5!

$^{10}C_5 = \frac{10*9*8*7*6}{5*4*3*2*1}$

$^{10}C_5 = \frac{30240}{120}$

$^{10}C_5 = 252$

A rectangular flower bed is 7 m long. If the boundary

tester [92]

<h2>Given :-</h2>

Length of flower bed = 7 m

Perimeter of boundary = 22 m

<h2>To Find :-</h2>

Breadth
Area

<h2>Solution :-</h2>

As we know that

$\sf \blue{Perimeter = 2(l + b)}$

22 = 2(7 + b)

22 = 14 + 2b

22 - 14 = 2b

8 = 2b

$\sf \: \dfrac{8}{2} = b$

$\bold{\boxed{b=4} }$

<h3>Breadth = 4 m.</h3>

Now,

$\sf \orange{Area = l \times b}$

$Area = 7 \times 4$

$\sf \: Area = 28 \: {m}^{2}$

Area=28 $\bold{ m^2 }$
