Given that y varies inversely as x then:
y=k/x
where
k is the constant of proportionality given by:
k=yk
but
y=27 when x=2
thus
k=27×2=54
hence the function will be:
y=54x
The value of x when y is 9 will be:
9=54x
thus
x=9/54
x=1/6
Answer: 2 2/3
Step-by-step explanation:
we have to turn this into a improper fractions first (so its something like a bobble-head)
(2 2/5) 5 x 2 = 10 + 2 = 11/5
(3 1/4) 3 x 4 = 12 + 1 = 13/4
Then add those two.
11/5 + 13/4
11 + 13 = 24
5 + 4 = 9
so now its time to put it in simplest form 8/3
Now 8 divided by 3...BUT WAIT...3 can't go into 8
Now we turn it into a Mixed Number 2 2/3

Answer:
10) area of 130° segment 4.5 in²
Step-by-step explanation:
10) area of full circle = πr² = (3.14)(2²) = 12.56 in²
area of 130° segment = (130/360)(12.56) = 4.54 in²
