Calculate the annual return percentage
const2013 [10]
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%

b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%

There are approximately 113 million TVs in the United States. Each uses, on average, 76 W of power and is turned on for 6.3 hour
ioda

Answer:

76 W *\frac{1kW}{1000 W}= 0.076 kW

0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}

113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh

And finally we can convert this into money like this:

54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6

So they spent every day approximately in total $ 4815291.6 dollars

Step-by-step explanation:

For this case we can convert the average power into Kw like this:

76 W *\frac{1kW}{1000 W}= 0.076 kW

Now on average we know that one person use on average this power over 6.3 hours per day so then we have the following consumption rate:

0.076 kW * 6.3 \frac{hours}{day}= 0.4788 \frac{kWh}{day}

And now we know the total population so then the total consumption per day would be:

113x10^6 people * \frac{0.4788 kWh}{people}= 54104400 kWh

And finally we can convert this into money like this:

54104400 kWh *\frac{0.089 dollars}{1 kWh}= 4815291.6

So they spent every day approximately in total $ 4815291.6 dollars
