Answer:

24.5

Step-by-step explanation:

Year 2000 would be 1, so year 2016 would be 17

Your equation is 1.5x - 1, and since we have x = 17, we simply plug it in:

Find the area of rectangle with sides 2 5/6 and 4 4/7

g100num [7]

<h3>Given :</h3>

Length = $\sf2\dfrac{5}{6}$ cm.
Breadth = $\sf4\dfrac{4}{7}$ cm.

The area of rectangle.

<h3>Solution :</h3>

Area of rectangle = Length × Breadth

$\sf=2\dfrac{5}{6}\times4\dfrac{4}{7}$

$\sf=\dfrac{17}{6}\times\dfrac{25}{7}$

$\sf=\dfrac{17\times25}{6\times7}$

$\sf=\dfrac{425}{42}$

<h3>Area of rectangle is 425/42 cm².</h3>

Light travels at approximately 2.998*10^5 kilometers per second. There are 6.048*10^5 seconds in one week. About how many kilome

BartSMP [9]

Answer:

okay, you have pay special attention to time.i.e 60secs = 1 minute, 60 minutes = 1 hour, 24 hours in one day, and 7 days in one week. No. of seconds in one week we are told is 6.1048 x 10 ^5 seconds.

Step-by-step explanation:

s = d/t [ speed = distance/time]

therefor, rearranging, we get d = s x t

Since speed = 2.998*10^5 Km/s and time = 6.048^10^5

d = (2.998 x 10^5) x (6.048 x10^5) = (2.998 x 6.048) x 10 ^(5+5)

d = 18.131904 X 10^10 km

d = approximately 18.132 x 10^10 km (to 3 decimal places)
