Andru [333]

Answer:

10.8

Step-by-step explanation:

By sine rule:

\frac{x}{ \sin 81 \degree}  =  \frac{7}{ \sin 40 \degree}  \\  \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree}   \\  \\ x =  \frac{7 \times0.9876883406 }{0.6427876097}  \\  \\ x =  \frac{6.91381838}{0.6427876097}  \\  \\ x = 10.755992 \\  \\ x  \approx 10.8

Cassandra is creating an animated short film, and she needs 35 frames per second of film. He already has at least 200 frames.
scZoUnD [109]

Answer: C) f ≥ 35s - 200

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

She needs 35 frames (f) per second (s) ( we have to multiply the number of frames by the number of seconds) f ≥ 35s

She has already 200 frames (since we already have, we can subtract that to the needed frames per second)

f ≥35s -200  

Feel free to ask for more if needed or if you did not understand something.
