-5 -5
×= -5
Answer:
They arrive at the same time.
Step-by-step explanation:
If Alison spends 3 seconds to cover the last 1/4, it means that in 12 seconds will cover the four quarters because the acceleration is constant.
On the other hand Kevin spends 4 seconds to cover the last 1/3 of the distance, it means that in 12 seconds will cover three thrds.
Finally we can conclude that both of them spend the same time to cover the drag race.
Answer:
a) 357.29 Hz
b) 535.9375 Hz
Step-by-step explanation:
v = Velocity of sound in air = 343 m/s
l = length = 24 cm
a)
∴ Resonant frequency is 357.29 Hz
b) Here one third is filled with soda
So, length becomes 
∴ Resonant frequency is 535.9375 Hz
Answer:
n=2.5
Step-by-step explanation:
First, write an equation!
n+5n-6+2n+1=15
Now, combine like terms to make things easier.
8n-5=15
Cancel -5 from the left to isolate 5n as a variable.
8n-5+5=15+5
8n=20
Now divide both sides by 8.
8n/8=20/8
n=2.5
