In the diagram of circle K, tangents are drawn from point A to points B and C on the circle. If arc mBC = 96, then what is the m
rjkz [21]

Answer:

∠A = 84°

Step-by-step explanation:

Since AB and AC are tangent to the circle, ∠ABK = 90° and ∠ACK = 90°.

Angles of a quadrilateral add up to 360°, so:

∠A + 90° + 90° + 96° = 360°

∠A = 84°

Hannah is saving money for a car. She earns $160 each week working part time after school and on the weekends at Papa's Pizza. H
Yuliya22 [10]
From the problem we know that Hanna saves one-half of her paycheck each week, so she saves ( \frac{1}{2})(160)= \frac{160}{2} =80. Also, we know that her parents put $50 in her savings account each week, so the total amount she and her parents put in her saving's account is 80+50=130.
Since we know that Hanna currently has <span>$1,280 in her saving's account and each week she and her parents deposit $130 to the account, with </span>n representing the number of weeks, we can model the situation as follows:
f(n)=1280+130n

kykrilka [37]

Answer:

\frac{1}{5} probability

Step-by-step explanation:

P(Sold Out)= \frac{4}{20}

\frac{4}{20} =\frac{1}{5}

So since the experimental probability is the number of times an event occurs out of the total number of trials...

The answer to "what is the experimental probability that the band's  next show will be sold out?" Is \frac{1}{5}!!!

Hope this helped you!

Have a nice evening!
