Answer:
About 8
Step-by-step explanation:
I found this by doing 16 divided by 2 since half of 16 is 8and AC and OC are congruent so I think it is 8.
Step-by-step explanation:
1 year = 12 months
2yrs = 24 months
F(c) =100+5(24)
= 100+120
= $220

Answer:
AC= 20
Step-by-step explanation:
since the two figures are similar, CB Is congruent to FD
since image/preimage, 12/3 =4
The dilation is 4.
AC is congruent to EF
EF=5
4 x 5 = 20
AC=20
someone correct me if im wrong :)
