olchik [2.2K]

Answer:

15 outfits

Step-by-step explanation:

We have 3 possibilities for pants and 5 possibilities for tops.

The tailor has 3 possible pants to choose from and 5 possible tops to choose from. Using the Fundamental Counting Principle, we can simply multiply these two together to get the total number of possible outfits:

3 * 5 = 15 outfits

Or, we could make a tree diagram. See attachment. It will give the same answer.

Ipatiy [6.2K]

Answer:

\frac{c}{a} and \frac{b}{a}

Step-by-step explanation:

sinB = \frac{opposite}{hypotenuse} = \frac{AC}{BC} = \frac{b}{a}

tanC = \frac{opposite}{adjacent} = \frac{AB}{AC} = \frac{c}{b}

Thus

sinB tanC = \frac{b}{a} × \frac{c}{b} ( cancel b on numerator/ denominator )

                 = \frac{c}{a}

---------------------------------------------------------------------------

sinC = \frac{opposite}{hypotenuse} = \frac{AB}{BC} = \frac{c}{a}

tanB = \frac{opposite}{adjacent} = \frac{AC}{AB} = \frac{b}{c}

Thus

sinC tanB = \frac{c}{a} × \frac{b}{c} ( cancel c on numerator/ denominator )

                 = \frac{b}{a}

If cheese is $4.40 per kilogram, what should i pay for 200 grams
Contact [7]
1 kg is 1,000 grams.


200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.

Thus 200 g= 1/5 kg = 0.2 kg.



      1 kg of cheese is <span>$4.40, 
</span>
so 0.2 kg of cheese is \displaystyle{ \frac{0.2kg \cdot \$4.40}{1kg}}=4.40 \cdot0.2 \$= 0.88\$


Answer: $0.88
