Answer:
D: 5 : 8 and 20 : 32
Step-by-step explanation:
A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.
B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.
C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.
D is correct because 5 x 4 = 20 and 8 x 4 = 32.
another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....

Answer:
0.65g
Step-by-step explanation:
Decay rate = 50%
Decay rate = 0.5
where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'
Ao = 4.8
t = 88/44 = 4
k = 0.5
substitute these values in the equation
