A medical plan requires a patient to pay a $25.00 copay plus 20% of all charges incurred for a medical procedure. If the average

miss Akunina [59]

Let the original bill be $x$ , then the final bill after the charges been added are $1.2x+25$ , where $1.2$ is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)

The range of the original bill is
200 < $1.2x+25$ < 800, subtract each term by 25
175 < $1.2x$ < 775, divide each term by $1.2$
145.83 < $x$ < 645.83

Hence, the range of the original bill is between $145.83 and $645.83

The formula s = StartRoot StartFraction S A Over 6 EndFraction EndRoot gives the length of the side, s, of a cube with a surface

never [62]

Answer:

$2\sqrt{2}\ ft\ longer$

Step-by-step explanation:

<u>Area Of A Cube </u>

Suppose a cube with side length s, the area of one side is

$A_s=s^2$

Since the cube has 6 sides, the total area is

$A=6A_s=6s^2$

But if we have the area, we can solve the above formula for s to get

$A=6s^2$

$\displaystyle s=\sqrt{\frac{A}{6}}$

We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths

$\displaystyle s_1=\sqrt{\frac{1,200}{6}}=\sqrt{200}$

$\displaystyle s_1=10\sqrt{2}\ ft$

$\displaystyle s_2=\sqrt{\frac{768}{6}}=\sqrt{128}$

$\displaystyle s_2=8\sqrt{2} ft$

The difference between them is

$10\sqrt{2}\ ft-8\sqrt{2}\ ft=2\sqrt{2}\ ft\approx 2.83\ ft$

The side of the cube with area 1,200 square inches is $2\sqrt{2}\ ft$ longer then the side of the cube with area 768 square inches
