Line of symmetry is the line which cuts the figure into two same halves
or we can say that which passes through the figure such that it makes one half the mirror image of the other half
So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves
So
y=-2
Third option
21/25 is already a fraction and if you wanted it to be simplified, its already simplified to be 21/25.
805043 would be the answer i believe
Find the greatest common factor (GCF) of 9 and 12 using factor trees. The GCF is 3
Divide each term (9 and 12) over 3
9/3 = 3
12/3 = 4
So 9/12 reduces to 3/4
In other words, 9/12 = 3/4
--------------------------------------
Now focusing on 3/4, we can multiply top and bottom by the same value. Let's say we multiply top and bottom by 5
3*5 = 15
4*5 = 20
So 3/4 = 15/20
--------------------------------------
So two ratios equivalent to 9/12 are 3/4 and 15/20. There are infinitely other ratios that are equivalent.
In short, the answers are 3/4 and 15/20.
Answer:A is the correct answer
Step-by-step explanation:
Let x represent the number of female students that are left handed. There are 5 times as many right handed female students as there are left handed female students. This means that the number of female students that are right handed is 5x
Let y represent the number of male students that are left handed. There are 9 times as many right handed male students as there are left handed male students. This means that the number of male students that are right handed is 9x
The total number of left handed students is 18. Therefore
x + y = 18
The total number of right handed students is 122. Therefore
5x + 9y = 122 - - - - - - - - - -1
Substituting x = 18 - y into equation 1, it becomes
5(18 - y) + 9y = 122
90 - 5y + 9y = 122
- 5y + 9y = 122 - 90
4y = 32
y = 32/4 = 8
x = 18 - y = 18 - 8
x = 10
Total number of right handed female students is 5×10 = 50
Total number of right handed students is 122.
Probability that a right handed student selected at random is a female will be
50/122 = 0.4098
approximately 0.410
