Answer:
Alberto is incorrect. Perimeter is 42 units.
Step-by-step explanation:
Given:
The vertices of the triangle are
Perimeter of a triangle of length and width is given as:
Here,
Distance between two points and is given as:
So, the length ST is,
Width TU is,
Therefore, the perimeter is given as:
Perimeter = units.
Hence, the perimeter written by Alberto is incorrect as perimeter is not 18 units bu 42 units.
Answer:
bottom right
Step-by-step explanation:
for the side that says total cost u go up to 4 and for the one that says number of puzzles u go two over
The answer is C - The implied coefficient is 1.
Answer:
x = 3√3
y = 6
Step-by-step explanation:
The geometric mean relations between segments intersecting the long hypotenuse and its parts can be used to find the values of interest.
<h3>Altitude</h3>
x = √(9·3) = 3√3
<h3>Short side</h3>
y = √((9+3)·3) = 6
__
<em>Additional comment</em>
These right triangles are all similar, so corresponding sides are proportional. When the proportions are solved for a missing side, a geometric mean relation results. (The geometric mean of 'a' and 'b' is √(ab).)
Identify the segments above the horizontal line as w, x, y. (x and y are already identified in this figure.)
The ratio of short side to long side is ...
x/9 = 3/x ⇒ x² = 9·3 ⇒ x = √(9·3)
The ratio of short side to hypotenuse is ...
y/(9+3) = 3/y ⇒ y² = (9+3)·3 ⇒ y = √((9+3)·3)
Likewise, the ratio of long side to hypotenuse is ...
w/(9+3) = 9/w ⇒ w² = (9+3)·9 w = √((9+3)·9) = 6√3
Step-by-step explanation:
MEDIAN
71, 81, 89, 92, 93, 94, 94, 99
92 + 93 = 185 / 2 = 92.5
The median is 92.5
MODE
71, 81, 89, 92, 93, 94, 94, 99
The mode is 94
