Ipatiy [6.2K]3 years ago
3 0

Answer:

41.1764...%

Step-by-step explanation:

60% on 50 questions is 30/50 correct since 30÷50=.6=60%

Between 30 and 50(inclusive) there are 21 numbers.(30,31,32...49,50).

There are 51 possibilities of scores,1-50/50 or 0/50

21/51=0.411764...

Every female chicken lays 4 eggs. What is the constant of proportionality for the ratio of eggs to female chickens? 4 3
satela [25.4K]

Since every female chicken lays 4 eggs, if you have one chicken you have 4 eggs, if you have two chicken you have 8 eggs, and so on.

We can even build a little table to show some values:

\begin{array}{c|c}1&4\\2&8\\3&12\\4&16\\5&20\\\vdots & \vdots\\n& 4n\end{array}

So, as you can see, the ratio between the number of eggs and the number of female chicken is 4.

prisoha [69]
You have $15 and admission is $5, so you know have $10 before doing any games. If you wanted to play 12 games, you would need $10.20, which you do not have. But, if you wanted to play 11 games, then you would need $9.35, which is just under $10.

So the maximum amount of games that you could play would be 11 games.
