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

100% of what number is 61
Dominik [7]

" 100% " means "the whole thing",
and "is" can be replaced by "is equal to".

You have said "The whole thing of a number is equal to 61."
or
                       "61 is equal to the whole thing of a number."

The only number that 61 can be equal to is 61.
