Answer:
Ana still needs to read 1/5 of th journal
Step-by-step explanation:
charging the phone for 1 minute ,it has 2%
i.e,1----->2
After 2 minutes from that time ,i.e total 3 minutes
it has 6% charge
i.e,3--------->6
from the both the above cases ,1 minute provide 2%=6/3
=2
Hence,
for getting 50%charge=50/2
=25 min
and,for 90 %charge=90\2
=45 min
0.01x=0.6
0.01x/0.01=0.6/0.01
x=0.6/0.01 (simplify)
x=60
For answer A, since the constant 5+. The line would go [ 3, 8, 13, 18, 23, 28, 33, 38, ] and so on.
