Answer:
202.
Step-by-step explanation:
So we know that there was 45 people who showed up to the last game, and they want 4.5 times that amount for the next game. So when we here the word times, what comes to mind? Multiplication. So that means we have to times 45 by 4.5, and we get 202.5 . And the school at least wants 202 people to attend the next game because when I hear at least I think round down. (But if you have to round up it would be 303.)

Answer:
Answer:
835.29 Hz
Explanation:
When moving towards the source of sound, frequency will be given by
f*=f(vd+v)/v
Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.
Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then
f*=800(15+340)/340=835.29411764704 Hz
Rounded off, the frequency is approximately 835.29 Hz
