Answer: For plato family
A fossil with 47% of its carbon remaining is approximately how old
2998
A fossil that is 7000 years old will have approximately
17%
Step-by-step explanation:
385=15n+85
385-85=15n
300=15n
300/15=n
20=n
<span>Question No.2
</span>
speed= distance/ time
1200km/0.006s= 200 000 km/s
<span>Question 4
</span>
wavelength = wavespeed / frequency
wavespeed = 16/8 = 2
Question 5
(400/60s) = 6.6667 waves/ sec (Hz).
<span>Velocity = 0.008m/sec. </span>
<span>Wavelength = (v/f) = 0.008/6.6667 = 0.0012 metre (1.2mm).

Answer:
-3
3/2
Step-by-step explanation:
Y intercep is the point where the line intercepts the y axis. That is 3 in this graph.
slope. Choose two points. For the sake of explainin, I am choosing
(-3,1)
and (0,3). That’s the y intercept!!
The slope is the rate of increase. We have to measure it like we do with stairs. The rise divided by the run
the rise is 2. See the picture. The run is 3(change in x) the x increases by 3 between 2 integer points while the y changes by 3(change in y —>3 minus 1)
Rise= 3
run =2
Slope=rise/run=3/2
