The answer would be B. 114
Inflation Rate= CPI2-CPI1/CP1 x 100
Answer:
About 113.1
Step-by-step explanation:
Area of a circle= πr2
Radius= 6
6x6=36
36π= About 113.1
<h3>Angles. Triangle angles.</h3>
The sum of angles of a triangle equals 180°.
Therefore:
|∠EAB| + |∠ABE| + |∠BEA| = 180°
Susbtitute
|∠EAB| = 14°
|∠ABE| = 45°
|∠BEA| = x°
14° + 45° + x° = 180°
59° + x° = 180° |<em>subtract 59° from both sides</em>
<h3>x° = 121°</h3>
∠BEA and ∠CED are vertical angles. Vertical angles are congruent, meaning that they have the same angle measure.
Therefore
<h3>|∠CED| = 121°</h3>
In ΔCDE:
|∠CED| + |∠DCE| + |∠EDC| = 180°
Substitute:
|∠CED| =121°
|∠DCE| = 27°
|∠EDC| = y°
121° + 27° + y° = 180°
148° + y° = 180° |<em>subtract 148° from both sides</em>
<h3>y° = 32°</h3>
<h2>|∠EDC| = 32°</h2>
1500 + 0.45x < 1.70x
1500 < 1.70x - 0.45x
1500 < 1.25x
1500/1.25 < x
1200 < x.....so she would have to sell 1201 cards to make a profit
