Answer:
6 sqrt(3) = y
Step-by-step explanation:
We can use the leg rule to find y
hyp leg
----- = -------
leg part
9+3 y
----- = -------
y 9
Using cross products
12*9 = y^2
108 = y^2
Taking the square root of each side
sqrt(108) = sqrt(y^2)
sqrt(36 *3) = y
6 sqrt(3) = y
Based on the data presented, it can be concluded out of the 52 females 26 prefer cats.
<h3>How to read the graph?</h3>
To read the graph we must take into account that the rows refer to the preference of men, preference of women and those who have no preference.
On the other hand, the columns refer to the number of students of both genders who prefer or do not prefer each animal. Additionally, adding all the students of each gender we have the total of the sample.
According to the above, the total sample of female students would be 52.
According to the above, the fraction that expresses this relationship correctly is:

Answer:
7
Step-by-step explanation:
Since both chords are congruent and the distance of the x and 7 are equidistant from the center, then the value of x will also be 7.
Left side chord will have a value of y + 10
The right side chord will have a value of y + 10
Now since the right angles on both sides are equal, then x = 7.
Answer:
The total number of students in the gymnastics are <u>70</u>.
Step-by-step explanation:
Given:
Fifty-six students in a gymnastics club participated in the last fundraiser.
In the gymnastics club 80% of the students in the club participated in the fundraiser.
Now, to find the total number of students in the gymnastics.
Let the total number of students be 
Number of students participated in the club = 56.
Percent of students participated in the club = 80%.
According to question:



<em>Dividing both sides by 0.8 we get:</em>

Therefore, the total number of students in the gymnastics are 70.
