Answer: 40/9
tan A = BC/AC = 40/9
Step-by-step explanation:
40% of 20 is 8 Boys
60% of 20 is 12 Girls
50% of the Girls is 6
25% of the Boys is 2
6 + 2 = 8 Students wore glasses
Hope this helps!
Answer:
![y=\frac{4}{5}x+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B5%7Dx%2B4)
Step-by-step explanation:
You'll need to get this equation in slope-intercept form by solving for y. I do a little extra here to get it in the correct form, but I think it's pretty clear. Let me know if I need to clarify.
![\\\\\frac{8x}{5}-2y=-8\\\\-2y=-\frac{8x}{5}-8\\\\2y=\frac{8x}{5}+8\\\\y=\frac{4}{5}x+4](https://tex.z-dn.net/?f=%5C%5C%5C%5C%5Cfrac%7B8x%7D%7B5%7D-2y%3D-8%5C%5C%5C%5C-2y%3D-%5Cfrac%7B8x%7D%7B5%7D-8%5C%5C%5C%5C2y%3D%5Cfrac%7B8x%7D%7B5%7D%2B8%5C%5C%5C%5Cy%3D%5Cfrac%7B4%7D%7B5%7Dx%2B4)
Once it's in slope-intercept form, both the slope and the y-intercept are readily available so you can easily graph it. I graphed both of them in the attached image so you can see that they are the same line.
