There are 40 runners in a race. How many ways can the runners finish first, second, and third?
Answer:
117600
Step-by-step explanation:
50 x 49 x 48 = 117,600 ways
You have 50 possible for 1st, 49 for 2nd, 48 for 3rd
or
Permutations 50P3 = 117,600
There are total 59280 ways that can the runners finish first, second and third in a race.
What is permutation?
A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Formula for permutation[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]
Where,
[tex]nP_{r}[/tex] is permutation.
n is total number of objects.
r is number of objects selected.
According to the given question
Total number of runners, n = 40
Total number of runners to be selected for first, second and third position is 3 i.e. r = 3
Therefore,
The number of ways can the runners finish the first, second and third is given by
[tex]40P_{3} = \frac{40!}{((40-3)!} =(40)(39)(38)=59280[/tex]
Hence, there are total 59280 ways that can the runners finish first, second and third in a race.

Alexander has a Collection of baseball cards he wants to organize it’s way book use the table to determine how many pages he will hold 234 cards
Step-by-step explanation:
setup a porportion. Make it pages/cards. Solve for the number of pages, p.
[tex] \frac{3}{18} = \frac{p}{234} [/tex]
reduce the fraction 3/18
[tex] \frac{1}{6} = \frac{p}{234} [/tex]
cross multiply
[tex]6p = 234[/tex]
divide by 6
[tex] \frac{6p}{6} = \frac{234}{6} [/tex]
[tex]p = 39 \: pages[/tex]
There are 39 pages he will hold for 234 cards.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent
to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
Alexander has Collection of baseball cards which he wants to organize.
Now, By the given table;
The ratios for Pages to cards are,
Number of pages : Number of cards
⇒ 3 : 18
After simply;
⇒ 1 : 6
And, 6 : 36 = 1 : 6
Thus, Let number of pages for the given cards = x
Then, By the definition of ratio we get;
x : 234 = 1 : 6
Solve for x as;
x / 234 = 1/6
x = 234/6
x = 39
Thus, There are 39 pages he will hold for 234 cards.

Consider the following two loans for P=$5,000. Loan A: 2.5 year loan, annual interest rate of 12%. Loan B: 5 year loan, annual interest rate of 6%. Both loans are paid monthly, and their interest is compounded monthly. Calculate the absolute difference between the total interest paid on both loans. Round your answer to the nearest cent.
53.5 dollars is the total interest paid on both loans.
What is Compound Interest ?
Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Loan A :
CI = P(1 + R/100)∧(T) - P
CI = 5000(1 + 12/100)∧(5/2) - 5000
CI = 1637.66
Loan B :
CI = P(1 + R/100)∧(T) - P
CI = 5000(1 + 6/100)∧(5) - 5000
CI = 1691.13
difference between two CI
= 1691.13 - 1637.66
= 53.47
= 53.5 dollars
