Answer:
$6
Step-by-step explanation:
$25 divided by 50 = 50 cents a CD
50 cents = 0.5
Now do,
$12 x 0.5 = $6
$6
This is a geometric progression pattern with the common ratio of negative 0.5.
The next three would be -0.5, followed by 0.25, followed by -0.125
The answer is 12. I am 1,000,000% positive that it is the correct answer
You form a rhombus.
Draw an equilateral triangle, and then mirror it around its base. All the sides are clearly equal, because they are all sides of the same equilateral triangle.
Moreover, the top and bottom angle are 60°, because they are angles of an equilateral triangle, while the left and right angles are 120, because they're 60+60 angles.
Plugging 10 for k in the expression gives us
We simplify this expression to
251 is your answer
