Josiah downloads 44 songs including 16 songs by his favorite band. Express as a decimal the number of songs by his favorite band
that Josiah downloaded out of the total number of downloads. Is the decimal terminating or repeating?
2 answers:
Using a calculator, 16/44 = 0.363636363636363636... it goes on and on. It is repeating. If it was terminating, you would see the end.
There are a few ways to report the number, I'm not sure which one you need. A common way to show a repeating decimal is to put a line above it, I will upload a picture of what I mean.
Otherwise, you can round it.

Answer:
(a)∴A=$6753.71.
(b)∴A=$1480.24
(c) ∴P=$7424.70
(d)∴P=$49759.62
(e)∴P=$5040.99
(f) ∴P=$2496.11
Step-by-step explanation:
We use the following formula
A=amount in dollar
P=principal
r=rate of interest
(a)
P=$2,500, r=5%=0.05,t =20 years , n= 4
=$6753.71
∴A=$6753.71.
(b)
P=$1,000, r=8% =0.08,t =5 years , n= 2
=$1480.24
∴A=$1480.24
(c)
A=$10,000, r=6% =0.06,t =5 years , n= 4
∴P=$7424.70
(d)
A=$100,000, r=6% =0.06,t =10 years , n= 12
∴P=$49759.62
(e)
A=$100,000, r=10% =0.10,t =30 years , n= 12
∴P=$5040.99
(f)
A=$100,000, r=7% =0.07,t =20 years , n= 4
∴P=$2496.11
