Divide the total number of students by the number of classes into which they're, well, divided.
144 students/6 classes
This comes out to be 24, so you have
24 students/1 class, or 24 students per class

What is the value of x? Round to the nearest tenth. Please Help
Elodia [21]

Answer:

<h2>x = 6.5 cm</h2>

Step-by-step explanation:

The segment 20.2 cm is the tangent. Therefore x and 20.2cm are perpendicular.

Use the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=x,\ leg=20.2cm,\ hypotenuse=(14.7+x)cm

Substitute:

x^2+20.2^2=(14.7+x)^2           <em>use (a + b)² = a² + 2ab + b²</em>

x^2+408.04=14.7^2+(2)(14.7)(x)+x^2          <em>subtract x² from both sides</em>

408.04=216.09+29.4x        <em>subtract 216.09 from both sides</em>

191.95=29.4x         <em>divide both sides by 29.4</em>

x\approx6.5\ cm

a record store is having a sale during which all items will be sold at 25% less then marked prices. How much will a CD marked $1
BARSIC [14]

Answer:

$12

Step-by-step explanation:

If you're taking off 25% of the regular cost, "taking off" means subtracting.  So if we subtract 25% OF 16, the word "of" means to multiply here.  So our expression then becomes:

16 - .25(16)

16 - 4 = 12

So the CD will sell for $12.
