The correct answer to this question is this one: "4/45"
inverse variation ---> wt = constant
let wt=k
<span>put w=4, t= 1/5 and find k
</span>
So the correct answer for k is 4/5
wt = 4* (1/5) = 4/5 = k\
so your function is
wt = 4/5 or t= 4/(5w)
now to get t, when w=9, just put w=9 in t=4/(5w)
So that makes 4/45
I'm sure you know the formula for Pythagoras Theorem.
The formula is 
C = Your hypotenuse
A + B = The other two adjacent sides.
So you plug in the numbers
And you'll get the answer, which is 56.
Answer:
D {-7, 0}
Step-by-step explanation:
The GCF is 3x
3x(x+7) = 0
x = {-7, 0}
Step-by-step explanation:
a)
well, it is kind of written already :
228 miles and 6 gallons.
so, miles/gallon = 228/6 = 38 miles/gallon.
b)
it is not mentioned, but I guess we have to assume that he got the same miles/gallon ratio on this trip as well.
so, again
38 miles/gallon
and he used 9 gallons.
so, he drove 38×9 = 342 miles
