For this case we must simplify the following expression:

We have that by definition of properties of powers that is fulfilled:

Then, rewriting the expression:

Answer:

1500m=1.5km so 1500 divided by 10= 150s it takes 150s to cover a distance of 1.5km
Answer:
- 57
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
Here a = 13 and d = - 2.5, thus
= 13 + (28 × - 2.5) = 13 - 70 = - 57
2(319) +3(264) = 1430
There are 1,430 pages.
So .27 means .27/1 or 2.7/10 or 27/100 or 270/1000 and so on
