Each Americana chicken lays 2 eggs per day and each Delaware chicken lays 1 egg per day.
Allysa only sells eggs by the full dozen for $2.50. Determine how much money she expects to take
in at the end of the first week with her 12 chickens.

$30

Step-by-step explanation:

-One week has 7 days, so the total number of eggs laid by both chickens:

-One doze is equivalent to  12 items. There's only one full dozen unit in 21 pieces.

Hence, she makes $30 in week one.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
