Light travels at 300,000,000 meters/second. It is calculated as 3 x 10^8.
Earth is 3.99 x 10^16 meters away.
I used the formula (3.99 x 10^16) divided by 300,000,000.
The answer is 133,000,000 seconds
Answer:
B
Step-by-step explanation:
10% of 49.99
0.1 x 49.99 = 4.99
49.99 - 4.99 = 45.00
30% of 60.00
0.3 x 60 = 18
60 - 18 = 42.00
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.
