Answer:
17,250
Step-by-step explanation:
since there are 1000 grams for each kilogram
We have the triangle 30° - 60° - 90°.
The lenght of the sides are in proportion: 

6/8ths are left you have to cross multiply to get the answer
Answer:
yes
Step-by-step explanation:
well plug it in: y=6x -> y=6(3/9) and solve, yes if theres a slope of 1
Domain are x values (independent variable);
Speed would be independent so what speeds can be used ? -30 mph, 30 mph, 1000 mph?
Can a car go 0 mph?
What is realistic?
I would say 0 greater or equal to x greater than whatever you think is beyond the max that a car can go.
