For this case we must find an expression equivalent to:
By definition of power properties we have to meet:
Then, we can rewrite the expression as:
Answer:
Answer:
560 Tickets
Step-by-step explanation:
40 tickets in 30 minutes will become 80 tickets in 60 minutes (an hour)
Multiply 80 by 7 to get 560
Answer:18
Step-by-step explanation:2(18)+3=1/2(18)+30
36+3=9+30
39=39
Answer:
m(arc CD) = 122°
Step-by-step explanation:
Since, measure of an arc = 2 × (Angle subtended by the arc at the circumference of the circle)
m(arc CD) = 2[m(∠CBD)]
By triangle sum theorem in ΔBCD,
m∠CBD + m∠BDC + m∠DCB = 180°
m∠CBD + 49° + 70° = 180°
m∠CBD = 180° - 119°
m∠CBD = 61°
Therefore, m(arc CD) = 2 × 61°
m(arc CD) = 122°
