Enter the correct unit of measurement to complete the conversion. 1,000 seconds = 1 what?
Anvisha [2.4K]

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

Find the first three terms of the series represented by the formula 3(- 2)(n - 1).
enyata [817]

Answer:

0, - 6, - 12

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the formula

a₁ = 3(- 2)(1 - 1) = 3 × - 2 × 0 = 0

a₂ = 3(- 2)(2 - 1) = 3 × - 2 × 1 = - 6

a₃ = 3(- 2)(3 - 1) = 3 × - 2 × 2 = - 12

First 3 terms are 0, - 6, - 12

The sum of the measures of the interior angles of a convex polygon is 1080° Classify the polygon by the number of sides​
lozanna [386]

Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides
