Answer:
1120
Step-by-step explanation:
40% of 2800
= 40/100 × 2800
= 4/10 × 28
= 112/10
= 11.2 × 100
= 1120
First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256
These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)

There are 3600 seconds in an hour.
3600x6 = seconds in 6 hours.
= 21,600 seconds.
48 hours in a 2 days. 3600 seconds each hour.
48x3600= 172,800 seconds.
