As far as I can tell you are correct. The correct answer for x should be
-pi/3

If you plug x=+pi/3 into the expression cos(x/2 + pi/6), it ends i equaling 1/2, not 0.

How can I do ratios? I’ve been having a lot of trouble with this in my math class, and really need some help.

Katarina [22]

If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.

Please explain step by step for 0.67÷0.3=?

pentagon [3]

Multiply each of the numbers by a ten to a power that they both become whole numbers.

0.67 * $10^2$ = 67
0.3 * $10^2$ = 30

Divide as usual.

67 / 30 = 2 $\frac{1}{3}$

So, the answer is 2 1/3.

Name a point that is not coplanar with points A, B, and C.

boyakko [2]

Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.
