16 teams In a football league, each team plays each other twice , how many games are there in the football league in total ?

Brilliant_brown [7]

Answer:

120 games.

Step-by-step explanation:

We have been given that there are 16 teams in a football league. Each team plays each other twice. We are asked to find total number of games are there in the football league.

We will use formula $\frac{n(n-1)}{2}$ to solve our given problem.

Each team will play matches with one team less as it will not play match with itself.

We will divide all number of matches by 2 to avoid repetition.

$\frac{16(16-1)}{2}=\frac{16(15)}{2}=8*15=120$

Therefore, there are 120 games in the football league.

Renee has 1/4 yard of floral fabric. She cuts it into 5 equal pieces. How long is each new piece of fabric?

Zinaida [17]

Answer:

$\dfrac{1}{20}\ \text{yards}$

Step-by-step explanation:

Given that,

Renee has 1/4 yard of floral fabric.

She cuts it into 5 equal pieces.

We need to find the length of each new piece of fabric. It is equal to the total length divided by the total number of pieces. So,

$l=\dfrac{\dfrac{1}{4}}{5}\\\\=\dfrac{1}{4}\times \dfrac{1}{5}\\\\=\dfrac{1}{20}\ \text{yards}$

So, each new piece pf fabric is $\dfrac{1}{20}\ \text{yards}$ .
