The largest triangle and the triangle whose hypotenuse is x are similar. So:
(21 + 4)/x = x/4
Cross multiply:
x^2 = 100
x = 10

y-5=6*(x+2)
Step-by-step explanation:
The percent of the 7th graders that are in favor of school uniforms is 42.857% which can be rounded as 42.9%.
The survey results show there are a total of 112 7th-grade students and from this total, the number of students that support school uniforms is 48.
Let's calculate the percentage 48 represents:
- x = 48 x 100 / 112
- x = 4800 / 112
- x = 42. 857
This means the percentage of 7th graders that support uniforms is 42.857% which can be rounded to
