Are all fractions with a denominator of 9 recurring decimals investigate

1 answer:

7 0

No. For example, $\frac{18}{9}$ gives you a 2, which isn't a recurring decimal! You can try this for all sorts of multiples of 9 and you will see that they do not give you recurring decimals. However, there are some, e.g. $\frac{10}{9}$ which gives you 1.1111111....

Hope this helps!

There are 5 girls and 5 boys in a chess club. The club holds a round-robin tournament in which every player plays against every

Bess [88]

<span>1. In how many games does a girl play against a boy?
A: Because there are 5 girls, each will play against 5 boys, so in total is 5*5 = 25 times.

2. </span><span>In how many games does a girl play against another girl?
A: In this case, we only need to calculate how many girl pairs are there among these 5 girls, and it become a combination problem which can solved by </span> $C^{2}_{5}=\frac{5*4}{2*1}=10$

3.The fraction of games "B vs B" should be the number of "B vs B" (which is 10) divide the total number of the games "B vs B" & "G vs G" & "B vs G" (which is 10+10+25=45, see the analysis in 1.A and 2.A), so the fraction should be 10/45=2/9

4.One person will have to play against 9 people at the tournament, and the total number of the games is 45, so the fraction should be 9/45 = 1/5

Hillary rolls 2 number cubes numbered 1 through 6 while playing her favorite board game. She will get a second turn if she rolls

Nataly [62]

Answer:

1 in 18

Step-by-step explanation:

The highest possible number Hillary can get is 12, meaning that the only odd number above 10 which she can get is 11.

There are two possible ways in which Hillary can get 11:

(a) Hillary rolls a 5 on her first cube and a 6 on her second cube

(b) Hillary rolls a 6 on her first cube and a 5 on her second cube

There are 34 other possible outcomes which Hillary can have when rolling her number cubes, for a total of 36 possible outcomes.

Since 2 of these outcomes result in a roll of 11, Hillary has a 2 in 36 chance of rolling an 11, which can be simplified as 1 in 18.

African Americans in a St. Louis suburb sued the city claiming they were discriminated against in schoolteacher hiring. Of the c

Serjik [45]

Answer:

Yes, they are being underrepresented.

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

The Population of African Americans in St. Louis suburbs 5.7% . Therefore we can assume that the school system should have about 5.7% of their teachers being African Americans. Since we are given the amount of total teachers and the amount of African American teachers in the school, we can calculate the percent of African American teachers by using a simple Rule of Three property (demonstrated in the picture below).

405 Total teachers ⇒ 100%

15 African American ⇒ x

$\frac{15*100}{405} = x$
