Answer:
Step-by-step explanation:
Inverse variation is written as
which, in words, says "y varies inversely with x". If cavities varies inversely with time brushing, then

We are given the initial condition for which we need to solve for k:
c = 4 when t = 30:
so
k = 120.
Now we will use that value of k to solve the problem of how many cavities, c, would she have if she brushed her teeth 120 seconds, t, each night:
(the 120 on top is the k value and the 120 on the bottom is the number of seconds she brushed) to get
c = 1
To solve this problem you must apply the proccedure shown below:
1. You have that the radius and the height of the cylinder are:

2. So, you must calculate the area:

3. Substitute the values into the formula:

4. When the radius and the height are doubled, you obtain:

5. The factor is:
The answer is: B.
Answer:
$3.65 per chicken
Step-by-step explanation:
Divide the coat of he chickens by the number of chickens.
18.25/5
= 3.65
So one chicken would cost $3.65.
