Answer:
<h2>71.8%</h2>
Step-by-step explanation:
The shape described in question is a square overlaid with two quarter circles(a semi circle)
Area of the figure = Area of the square + area of the semi circle
Area of the figure = 
L = length of a side of the square = 12in
r is the radius of the semi circle = 6in
Area of the figure = 
Area of the figure =
= 200.55in²
Since the shaded portion is a square;
percent of the total area is shaded = area of the square/total area * 100%
percent of the total area is shaded = 144/200.55* 100
percent of the total area is shaded= 71.8%
Answer:
yes
Step-by-step explanation:
-2.5 - 3.25 = - (2.5+3.25) = - 5.75
Answer:
97.8
Step-by-step explanation:
All you need to do is times the percentage with the number(make sure to change the percent to a decimal)
104 x 0.94 = 97.76
97.8
Answer:
RIGHT Angle Addition Postulate.
Step-by-step explanation:
Applying the RIGHT Angle Addition Postulate gives m∠AEB + m∠BEC = m∠AEC. Applying the substitution property gives 45° + m∠BEC = 90°. The subtraction property can be used to find m∠BEC = 45°, so ∠BEC ≅ ∠AEB because they have the same measure. Since Ray E B divides ∠AEC into two congruent angles, it is the angle bisector.
