1200 students x 30% = 1200 x 0.3 = 360 students.
60 teachers x 15% = 60 x 0.15 = 9 teachers.
Total = 360 + 9 = 369
Answer:
40 degrees
Step-by-step explanation:
Supplementary angles are angles in which their measures combined add up to 180 degrees. So we can set up an equation:
140+x=180
x=40
So the other supplementary angle is 40 degrees
-⅔ (6x + 9) = 18
Apply distributive property. Multipy -⅔ to 6x and 9.
-4x - 6 = 18
Add 6 to both sides so -4x can be alone.
-4x - 6 + 6 = 18 + 6
-4x = 24
To get x alone, divide both sides by -4.
-4/-4x = 24/-4
x = -6
x = -6 is your answer. I hope this helps! Let me know if you need more help or if I got something wrong.
Since the whole length of the rectangle is 8, and the line across isnt exactly in the middle, (but just a little bit farther than the 4 mark) ... Then the correct answer is:
D. 4 1/2 units
