Answer:
Step-by-step explanation:
6 x 8 = 48
11,04 x 6 = 66,24
66,24/48 = 1,38$
Answer:
A
Step-by-step explanation:
300 minus 15 ( times each week that passed) would equal how much she owes
It's a value you should probably memorize:

You can derive it using some trigonometric identities, other known values of cosine, and properties of the cosine function. For example, using the double angle identity for cosine:

If
, then

and you probably know that
, so

When we take the square root, we should take the positive root because
whenever
:

90º (-270º): (x,y) ---> (y, -x)
180º (-180º): (x, y) ---> (-x, -y)
270º (-90º): (x,y) ---> (-y, x)
Answer:
B
Step-by-step explanation:
Given
14 + 10y ≥ 3( y + 14) ← distribute
14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )
14 + 7y ≥ 42 ( subtract 14 from both sides )
7y ≥ 28 ( divide both sides by 7 )
y ≥ 4 → B
