At an electronics store the price of a tablet is marked down 15% to 212.50

Answer:

1000 seconds = 1 million milliseconds

1000 seconds = 16.67 minutes

1000 seconds = 0.28 hour

Step-by-step explanation:

Given

1,000 seconds

Required:

Convert to similar units

The given parameters is a unit of time.

Other units of time are

1. Milliseconds

2. Minutes.

3. Hour

And lots more

We'll convert the given time to the above time units but first, take note of the following

1. 1 seconds = 1000 millisecond

2. 60 seconds = 1 minutes

3. 3600 seconds = 1 hour

To convert the time in seconds to milliseconds, we make use of (1) above

If 1 seconds = 1000 milliseconds, we calculate 1000 seconds by multiplying both sides of the equation by 1000

So, we have

1 seconds * 1000 = 1000 milliseconds * 1000

1000 seconds = 1 million milliseconds

To convert the time in seconds to minutes, we make use of (2) above

If 60 seconds = 1 minutes, we calculate 1000 seconds by multiplying both sides of the equation by 1000/60

So, we have

60 seconds * 1000/60 = 1 minute * 1000/60

1000 seconds = 1000/60 minutes

1000 seconds = 16.67 minutes

To get this time in hours, we make use of (3)

If 3600 seconds = 1 hour, we calculate 1000 seconds by multiplying both sides of the equation by 1000/3600

So, we have

3600 seconds * 1000/3600 = 1 hour * 1000/3600

1000 seconds = 1000/3600 hour

1000 seconds = 0.28 hour

Answer:

E  (b/3) +3

Step-by-step explanation:

3c =b

c+3 = ?

Solve the first equation for c

3c=b

Divide by 3

3c/3 = b/3

c = b/3

Now replace c  with b/3 in c+3

c+3

(b/3) +3

Answer:

Answer E. is correct

Step-by-step explanation:

b = 3 * c --> c = 1/3 * b

c + 3 = 1/3 * b + 3 --> E.
