Step-by-step explanation:
Answer:You would have to use over 200 minutes in a month in order for the second plan to be preferable.
Step-by-step explanation:
Let x represent the number of minutes that you use in a month.
The first plan charges a rate of 25 cents per minute. It means that the cost of using x minutes in a month with this plan is 0.25x.
The second plan charges a monthly fee of $29.95 in addition to 10 cents per minute. It means that the cost of using x minutes in a month with this plan is
29.95 + 0.1x
For the second plan to be preferable, its cost would be lesser than the first plan. Therefore,
29.95 + 0.1x < 0.25x
29.95 < 0.25x - 0.1x
29.95 < 0.15x
0.15x > 29.95
x > 29.95/0.15
x > 200
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
The sibling cab either be male or female.
