Answer:

$63

Step-by-step explanation:

  • Penny = $0,01
  • Nickel = $0.05
  • Dime = $0.1
  • Quarter= $0.25
  • Number of pennies = 6*50 = 300
  • Number of nickels = 5*40= 200
  • Number of dimes = 4*50= 200
  • Number of quarters = 3*40 = 120

<u>Total amount of money:</u>

  • 300*0.01+ 200*0.05 + 200*0.1 + 120*0.25 = $63

What value is a permutation of n things taken r at a time divided by to get the combination of n things taken r at a time?
Lera25 [3.4K]

Answer:

A. r!

Step-by-step explanation:

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

P_{(n,x)} = \frac{n!}{(n-x)!}

Permutation of n things taken r at a time

P_{(n,r)} = \frac{n!}{(n-r)!}

Combination of n things taken r at a time:

C_{n,r} = \frac{n!}{r!(n-r)!}

Division:

\frac{P_{(n,r)}}{C_{n,r}} = \frac{\frac{n!}{(n-r)!}}{\frac{n!}{r!(n-r)!}} = \frac{n!}{(n-r)!} \times \frac{r!(n-r)!}{n!} = r!

So the correct answer is:

A. r!

How many miles per hour is this? (one furlong is 18 mile, and a fortnight is 14 days. a furlong originally referred to the lengt
WITCHER [35]

the complete question is

While driving in an exotic foreign land you see a speed limit sign on a highway that reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is 1/8 mile, and a fortnight is 14 days. A furlong originally referred to the length of a plowed furrow.)

Step 1

<u>convert (furlongs per fortnight) to (miles per fortnight)</u>

180,000 furlongs per fortnight=180,000*(1/8)=22,500 miles per fortnight

Step 2

<u>convert miles per fortnight to miles per hour</u>

1 day=24 hour

14 day=24*14=336 hours

22,500 miles per fortnight=22,500/336=66.96 mph

therefore

<u>the answer is</u>

66.96 mph
