Paul, a dentist, determined that the number of cavities that develops in his patient's mouth each year varies inversely to the n

timofeeve [1]

Answer:

Step-by-step explanation:

Inverse variation is written as

$y=\frac{k}{x}$ which, in words, says "y varies inversely with x". If cavities varies inversely with time brushing, then

$c=\frac{k}{t}$

We are given the initial condition for which we need to solve for k:

c = 4 when t = 30:

$4=\frac{k}{30}$ 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:

$c=\frac{120}{120}$ (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

If the dimensions of the following cylinder are doubled, what factor will the surface area change by?

AVprozaik [17]

To solve this problem you must apply the proccedure shown below:
1. You have that the radius and the height of the cylinder are:
$r=8 in \\ h=6 in$
2. So, you must calculate the area:
$A1=2 \pi (r+h)$
3. Substitute the values into the formula:
$A1=2 \pi (8 in)(8 in+6in) \\ A1=703.71 in^{2}$
4. When the radius and the height are doubled, you obtain:
$A2=2 \pi (16 in)(16 in+12 in) \\ A2=2814.86 in^{2}$
5. The factor is:
$F=2814.8 in^{2}/703.71 in^{2} \\ F=4$
The answer is: B. $4
