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
ololo11 [35]

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

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

Help asap please i don't know the answer lol
Sveta_85 [38]

Answer:

H

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
