8.45 At some point in the season, the Unicorns had won 60% of their basketball games. After that point, they won 8 more games an

Answer:

The total number of games won by Unicorn is 40.

Step-by-step explanation:

We are given with a word problem
We are asked to find the number of unicorns played during the season
We can do this in two steps

Step 1: Finding the win percentage

Step 2: Finding the number of unicorns played during the season

Step 1 of 2

Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is $\frac{60}{100} \times(x-10)$

Combining the 8 games we get,

$\begin{gathered}\frac{60}{100}(x-10)+8=\frac{60}{100} \times x-\frac{60}{100} \times 10+8 \\0.6 x-6+8=0.6 x+2\end{gathered}$

Step 2 of 2

The unicorn totally won 65% of the games played.

That is $\frac{65}{100} \times x=0.65 x$

Equating both the equation gives

$\begin{gathered}0.6 x+2=0.65 x \\2=0.65 x-0.6 x \\2=0.05 x \\\frac{2}{0.05}=x \\40=x\end{gathered}$

Answer:

Step-by-step explanation:

The parallel line BC divides the sides AD and AE in proportion, that is

$\frac{AB}{BD}$ = $\frac{AC}{CE}$ , that is

$\frac{2}{3}$ = $\frac{AC}{4}$ ( cross- multiply )

3AC = 8 ( divide both sides by 3 )

AC = $\frac{8}{3}$ = 2 $\frac{2}{3}$ , hence

AE = AC + CE

= 2 $\frac{2}{3}$ + 4 = 6 $\frac{2}{3}$ → H
