Step-by-step explanation:
-1/3 a + 4 ≤ 0
3*(-1/3a) + 4*3 ≤ 0*3
-a + 12 ≤ 0
12 ≤ a
12 ⩾a
a⩾12

Answer:
50% or 1/2
Step-by-step explanation:
5 is half of 10 so the answer is 50%

Answer:
Approximately 35, or 34.67
Step-by-step explanation:
You can set up a cosine (adjacent over hypotenuse) equation.
cos38 = x/44
Move the 44 over and plug into the calcultaor.
x = 44cos38
(make sure the mode is on degree and not radian!)
