Ok, so we need to take 60 x 60.  That gives us 3600, which is the amount of seconds in 60 minutes.  Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day).  That gives us 86,400.  Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days).  That gives us the answer of <span>31536000.  Hope this helps!</span>

Answer:

  (b)  Hiking 10 feet due north, then hiking 10 feet due south

  +10 -10 = 0

A square patio has a perimeter of (8x + 48) feet. What is the length of the patio?
4vir4ik [10]

Answer:

2x+12

Step-by-step explanation:

We have a square patio, then each side of the patio has the same lengt. As we know the perimeter of a square is the sum of all sides. Then to know the length of the patio we just need to divide by 4 the perimeter.

\dfrac{(8x+48)}{4}=\dfrac{8x}{4}+\dfrac{48}{4}=2x+12

Then each side of the square patio has a length of  2x+12
