Answers
Answer:
12^4 = 20736
Step-by-step explanation:
The property of exponents used to simplify : 12^8/12^4
The division property :
a^x / a^y = a^(x - y)
Therefore ;
12^8/12^4
12^8 / 12^4 = 12^(8 - 4) = 12^4 = 20,736

Applying the inscribed angle theorems, the true statements regarding the given diagram are: B. m∠BCA = 25° C. m∠BOA = 50°
What is the Inscribed Angle Theorems?The inscribed angle theorems state that:
Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of intercepted arc = measure of central angle.∠BCA is an inscribed angle.
m(AB) is the intercepted arc = 50°
∠BOA is the central angle
m∠BCA = 1/2(m(AB) = 1/2(50) = 25°
m∠BOA = m(AB) = 50°
The true statements are:
m∠BCA = 25°
m∠BOA = 50°

Veronica took her friend out for a birthday dinner. She purchased an appetizer
for $7.95, two entrées for $12.95 and $15.95, two drinks for $3.50 each, and two
desserts for $6.95 each. She had a 25% off coupon. A sales-tax rate of 9.25% was
then added. How much was the meal? If Veronica left a 20% tip, how much did
she leave for the tip? *
Answers
Answer:
Veronica left a tip of $6.87
Step-by-step explanation:
3.50×2= 7
6.95×2= 13.9
7.95+12.95+15.95+7+13.9 = 41.8
0.25×41.8= 10.45
41.8-10.45= 31.35
0.0925×31.35 = 3
31.35+3 = 34.35
0.20×34.35 = 6.87

out of 500 tickets in a raffle, one ticket will win a $650 prize, two tickets will win a $530 prize, and ten ckets will win a $70 prize. The rest will win nothing. If you have a ticket, what is the expected payoff? $
Answers
1/500 = 650 (1.30)
2/500 = 350 (1.40)
10/500 = 70 (1.40)
487/500 = 0 (0)
Payoff 1.3 + 1.4 + 1.4 = $4.10
Subtract the cost of the ticket from that
