This is why the internet was invented so lets use an online math calculator.
Prime means that the only factors are 1 and itself.

Woah look at what I found!
263 is prime
1057 isn't? oh wow. 7 * 151
3163 is prime
157 is prime

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

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.

In a right triangle, CosA=0.352 and SinA=0.936 What is the approximate value of tanA?

mr_godi [17]

$\tan A=\frac{\sin A}{\cos A}$

Proof: $\sin\div\cos=\frac{o}h\div\frac{a}h=\frac{o}h\times\frac{h}a=\frac{oh}{ha}=\frac{o}a=\tan$

$\cos A=0.352,\ \sin A=0.936$

$\tan A=\frac{0.936}{0.352}$

$\boxed{\tan A=2.65\overline{90}}$ (round as needed)
