We have P = 3 x a (the formula of the perimeter); 26 = 3 x a ; we obtain a = 26/3;
Then, we have <span>the Pythagorean Theorem in one of two rectangular and congruent triangles :</span>
h² = a² - (a/2)² = a² - a²/4 = 4a²/4 - a²/4 =<span> 3a²/4</span>
It follows that
h = √(3a²/4) = a√3/2 ≈ 0,866*a ≈ 7,5 centimeter.
Answer:
<h2>D. 9</h2>
Step-by-step explanation:
X^2 - 4x + 4 = 0
(x - 2)^2 = 0 - Factor left side
x - 2 = 0 - Square root each side
x = 2 - add 2 to each side
Answer:
Step-by-step explanation:
We'll need the actual prices of one of the objects to figure it out...
but I've worked it out here in relation to each object....
Marker = 1/3 x cost of the pen
Marker = 1/3 x 1/3 x cost of book = 1/9 x cost of the book
Marker = 1/3 x 1/3 x 1/3 x cost of game = 1/27 x cost of the game
This probably isn't what you're looking for, but maybe it'll help?
