beks73 [17]

Hi there!

First, we need to find the area of the rectangles.

10 × 5 = 50
9 × 3 = 27

Now, we find the percent of increase.

27 ÷ 50 = 0.54

Convert into a percentage:

0.54 = 54%

And subtract from 100%.

100% - 54% = 46%

The answer is 46%.

Hope this helps!

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.

Answer:

Step-by-step explanation:

Since 3 is between -6 and 9 we use the first definition

f(3) = 6 x^2 +2

= 6(3)^2+2

= 6(9) +2

= 54+2

= 56

SIMPLIFY (81/16}-3/4 X {(25/9)-3/2 DIVIDED BY (5/2)-3}

babymother [125]

$(\frac{81}{16} - \frac{3}{4} )( \frac{\frac{25}{9}- \frac{3}{2}}{ \frac{5}{2} -3}) = \frac{-529}{48}$

If I understood correctly and didn't make any mistakes...
