Hey there! I'm happy to help!

A permutation is focused on a specific order, while a combination is not focused on the order but on the content of what is grouped.

AB and BA are different permutations because they are in different orders, but they are the same combination because they both contain the letters A and B.

So, we see that AB and BA are one combination.

AC and CA are also another combination because they are made up of the letters A and C.

Same goes for BC and CB, this is also one combinations.

This totals up to C. 3 combinations. Now you know the difference between permutations and combinations!

Have a wonderful day!

The speed of a stream is 2 mph. A boat travels 20 miles upstream in the same time it takes to travel 40 miles downstream. What i
nataly862011 [7]

Answer:

<em>The speed of a boat in still water is 6 miles per hour. </em>

Step-by-step explanation:

t = \frac{20}{s-2}  (upstream)

t = \frac{40}{s+2}  (downstream)

\frac{20}{s-2} = \frac{40}{s+2}

40 ( s - 2 ) = 20 ( s + 2 )

40s - 80 = 20s + 40

20s = 120

s = 6 mi / h

<em>The speed of a boat in still water is 6 miles per hour.</em>

1. A function can be represented verbally. For example, the circumference of a square is four times one of its sides.

2. A function can be represented algebraically. For example, 3x+6 3 x + 6.

3.A function can be represented numerically.

4. A function can be represented graphically.

I only found four, hopefully this helps.

A silversmith combined pure silver that cost $33.48 per ounce with 51 oz of a silver alloy that cost $24.35 per ounce. How many
Pavlova-9 [17]

Answer:

$38.31

Step-by-step explanation:

Given:

Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.

Question asked:

How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?

Solution:

At cost $24.35/ounce, pure silver is mixed = $33.48

At cost $1/ounce, pure silver is mixed = \frac{33.48}{24.35}

At cost $27.87/ounce, pure silver is mixed = \frac{33.48}{24.35}\times 27.87 = \frac{933.08}{24.35}  = 38.31

Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.
