Approximately 59% of films are rated R. if 930 films were recently rated, how many were rated R?
2 answers:
Answer:
About 549
Step-by-step explanation:
You have to set it up as a proportion, setting the percent and the number of movies equal.
X - Number of R-Rated movies.
Now, cross multiply, multiplying the numerator of the left and the denominator to the right, and vice versa.
Now, solve the inequality.
Now, round up.

Answer:
Option A. (-1, 0)
Step-by-step explanation:
In the figure attached,
Circle O is a unit circle (having radius r = 1 unit)
If a point A with central angles = θ, is lying on the circle then the coordinates of the point A will be,
x = r.cosθ
x = 1.cosθ = cosθ
and y = r.sinθ
y = 1.sinθ = sinθ
Therefore, coordinates representing the point A will be (cosθ, sinθ).
As per question the given point A is lying at P (a point having central angle θ = 180°)
Coordinates of point P will be
(x', y') → (cos180°, sin180°)
→ (-1, 0)
Therefore, Option A will be the answer.
