Jessica saved money to buy holiday gifts for her family. She started her holiday shopping by spending 2/7 of the money on flowers for her mother. Then she spent of 3/5
the remaining money on chocolates for her father. Jessica used the rest of the money
to buy a bracelet for her sister.
B) What fractional part of the money did Jessica spend on her father's gift?
C) If Jessica spent $12 on her sister's bracelet, how much money had she saved
altogether to buy holiday gifts for her family?

B) 3/7

C) $42

Step-by-step explanation:

B) 1-2/7=5/7 remaining.

5/7x3/5=15/35=3/7

C) She spent 2/7 on her mother and 3/7 on her father.  That leaves 2/7 for her sister.  $12 is 2/7 of $42 (12 divided by 2/7)

∠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°

it is probably the graph on the bottom right.
