Answer is -1/3
you would divide both sides by 18 to get the variable on its own and that would leave you with -6/18 and so you have to simplify it by dividing the numerator and denominator by the greatest common factor (6) to get your remaining simplified fraction of -1/3
Answer: it is a direct variation.
Justification:
In a direct variation the variables are related by a proportionality constant in this way:
y = k x
Tthan means that the value of y is always the product of a constant times the value of x.
The situation discribed for the coal may be written as:
number of tons of coal burned: c
number of hours: h
⇒ c = k × h
Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.
Answer:
r=11 m
Step-by-step explanation:
Too lazy to explain:
πr²h=v
3.14*r²*12=4560
r²≈121
r is 11 m
Answer:
2
Step-by-step explanation:
2x is the slope which is just 2
