I would say that in doing an experiment that will have multiple trials, if one of the variables is changed each time, say temperature or pressure amount, then average results between experiments will not be valid. They would only be valid if the same conditions applied for each one, to determine the inherent variability of the result.
First——//360/10=36. Each exterior angle is 36 degrees
3x+6=36
Subtract 6 from both sides
3x=30
X=10
Answer:
Step-by-step explanation
Use Pythagoras theorem. The distance between the cars, 8km, is the hypotenuse of a right angled triangle, one leg of which is 6km and the other of which is, say, x km
x = sqrt(8^2 - 6^2) km.
You can crunch the numbers.
What’s the height?
Formula is: V= πr2h
d=4 in
r=2 in
V= π•2^2•h
V= π•4•h
If h is 3, answer is B. If h is 9, answer is C. Good luck.
