So I have to compute the following but i don't know what they mean any help?
Gelneren [198K]

Answer:

Step-by-step explanation:

This is a Combination (as in permutation vs combination) question the symbol (n r) refers to "n choose r". This is sometimes written as nCr

i.e the question is asking you to find how many combinations each will yield when you chose r items from n item without repetition and order does not matter.

I will only do the first question for you and you can just follow the same steps to solve the rest of the questions.

Recall that

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

Consider question a) we are given (5 1) or ₅C₁

we can see that n = 5 and r = 1

If we substitute this into the formula:

₅C₁ = (5!) / [ (1!)(5- 1)!]

= (5!) / [ (5- 1)!]

= (5!) / (4!)

= (5·4·3·2·1) / (4·3·2·1)

= 5

hence ₅C₁ = 5

4 hundred-dollar bills 23 ten-dollar bills, 17 one-Dollar bills 46 Dimes And 19 pennies How much? Please help
Darina [25.2K]
Hundred dollar bills is 100 dollars so if you have four of them you get 400
ten dollar bills is 10 dollars so if you have 23 of them you have 230 
one dollar bills is 1 dollar so if you have 17 of them you 17 dollars 
400+230+17= 647
One dime is equal to 10 cents so if you have 46 of them you have $4.60 
One penny equals 1 cent so 19 pennies equal 19 cents  
$4.60+.19= $4.79 
$647+$4.79= $651.79<---- that's your answer

Please help i will give brainly
Aneli [31]

Answer:

20.4 ft

Step-by-step explanation:

Since they're similar triangles (same shape, but not necessarily the same size), then you can set them up as fractions to find the missing measure.

6/9.7 = ?/33

A quick way to do use this setup is to multiply 33 by 6, then divide by 9.7.

This gives you 20.4 ft
