The answer to 1. Is Reflection. The rigid motion show is called a Reflection
To do this let's put 129 where X is, like this: -12(129)+14(129)-6(129)
Now we multiply -12 by 129, which is equal to -1548.
Now we multiply 14 by 129, which is equal to 1806.
Now we multiply -6 by 129, which is equal to -774.
Now, let's put these numbers into an equation, like this: -1548+1806-(-774).
The answer to this equation is 1032.
I hope this helps.
Answer:
Ratio = 11:9
Boys = 440
Girls = 360
Explanation:
Given that, in a school,
Total number of students = 800
Also,
Percent of boys = 55%
Therefore, number of boys = 55% of 800
No. of boys = 55/100 x 800
No. of boys = 55 x 8 =
No. of boys = 440
Therefore, we will get,
No. of girls = (800-440)
No. of girls = 360
Therefore, we will get,
Ratio of boys to girls = 440/360
Ratio = (40*11)/(40x9)
Ratio = 11/9
Hence, the ratio of boys to girls is 11:9 and number of boys and girls is 440 and 360 respectively.
