Answer: 133.63 square units

Step-by-step explanation:

Pythagoras theorem = a^2+b^2=c^2

10^2 + b^2 = 18^2

b = sqrt (324-100)

b = sqrt 224

Height is to 20 what 10 is to sqrt of 224

h/20 = 10/sqrt 224 (cross multiplication)

h*sqrt 224 = 10*20

h*sqrt 224=200

h = 200/sqrt 224 (200/sqrt 224 = (200*sqrt 224)/200) = 13.36 (height)

Area = (base times height divided by two)

Area = (13.36*20)/2 = 133.63

Five chips numbered 1 through 5 are placed in a bag. A chip is drawn and replaced. Then a second chip is drawn. Find the probabi

Vesna [10]

12345

The odds of drawing an even chip are $\frac{2}{5}$ .

The odds of drawing an odd chip are $\frac{3}{5}$ .

You multiply the two $\frac{2}{5} x \frac{3}{5} = \frac{6}{25}$ .

Knowing you cannot simplify 6/25 any further, you now have your answer!

9x-23=49 what is the second step in this equation?

ladessa [460]

Answer:

Divide both sides by 9.

Step-by-step explanation:

To find the second step of the equation, we actually have to solve parts of the equation until we get to step 2.

Step 1: Add 23 to both sides.

$9x - 23 + 23 = 49 + 23$
$9x = 72$

Step 2: Divide both sides by 9.

$\frac{9x}{9} = \frac{72}{9}$
$x = 8$

Therefore, the second step is divide both sides by 9.
