First change the fraction to decimals or common denominators.
3/4 = 0.75 and 1/5 = 0.2
0.75 + 0.2 = 0.95 = 95/100 = 19/20
(3/4) = (15/20)
(1/5) = (4/20)
(15/20) + (4/20) = 19/20
Answer:
EFD
Step-by-step explanation:
AC/DE = AB/EF = BC/DF
So the correct order should be EFD

Answer:
26. B(t) = 500·1.075^t; B(6) ≈ $772
27. G(t) = 70·0.72^t; G(3) ≈ 26 g
Step-by-step explanation:
The equation with the plus sign is used when the value is increasing. The minus sign is used when the value is decreasing. The 'a' in each equation is the initial value.
__
26. B(t) = 500·1.075^t
B(6) = 771.65
The balance after 6 years is about $772.
__
27. G(t) = 70·0.72^t
G(3) = 26.127
About 26 grams are left after 3 days.
