Answer:
D
Step-by-step explanation:
The sum of any geometric sequence (if it converges, r^2<1) is of the form:
s(n)=a(1-r^n)/(1-r), a=initial term, r=common ratio, n=number of terms...
s(n)=30(1-0.4^n)/(0.6)
s(n)=50(1-0.4^n)
Since r<1 the sum of the infinite series is just:
s=50
Answer: They read for a equal amount of time.
Step-by-step explanation:
10/12 simplifies to 5/6, making these equal.
Proof:
10 divided by 2 equals 5, and 12 divided by 2 equals 6. This means that they are equal.
