\frac{1}{15} of the movies at the video rental store are animated children's movies.

Step-by-step explanation:

Fraction of children's movies at the rental store = \frac{1}{10}

Fraction of animated movies = \frac{2}{3} of children's movies

Fraction of animated movies = \frac{2}{3}*\frac{1}{10}

Fraction of animated movies = \frac{1}{15}

The diagram shows a right triangle with legs that measure 4 and 7.
anyanavicka [17]

Calculate the hypotenuse( h ) using Pythagoras' identity

h =√(4² + 7²) = √(16 + 49) = √65

sinΘ = 4 / √65  ⇒ cscθ = √65 / 4

cosθ = 7/ √65 ⇒ secθ = √65 / 7

tanθ = \frac{4}{7} ⇒ cotθ = \frac{7}{4}
