Step-by-step explanation:
Answer:
200×100=20000
200×1,000= 200,000
200×0.1= 20
200×0.01= 2
200×0.001= 0.2
Step-by-step explanation:
Answer:
T = 300 + 50x
Step-by-step explanation:
Tread mill calories burned = 300 calories
Weight lifting hours = x
Calories burned per hour during weight lifting = 50
Total calories burned :
Teadmill calories + weight lifting hours * calories burned per hour
T = 300 + 50x

Answer:
The annual depreciation rate is 72.86%.
Step-by-step explanation:
The information provided are:
- At the band’s peak of popularity, a signed Black Diamond poster sold for $500.
- Three years later, the band was almost forgotten, and the poster was worth only $10.
From the above data we know that the band's popularity depreciated.
The initial cost of a signed Black Diamond poster was, <em>a</em> = $500.
After three years the cost of a signed Black Diamond poster was, <em>y</em> = $10.
It can be seen that the value of a signed Black Diamond poster is decreasing exponentially over the years.
The formula for exponential decay or depreciation is:
Here,
<em>y</em> = final value
<em>a</em> = initial value
<em>r</em> = rate of depreciation
<em>x</em> = time
Compute the annual depreciation rate as follows:
Thus, the annual depreciation rate is 72.86%.
