a pelican. starts at 60 feet above sea level.it descends 60 feet to a catch fish. how do I explain it
2 answers:
The Pelican who is 60 feet above sea level is represented by +60.Now, he is trying to catch the fish which is at 0 level, means Sea level because the pelican is trying to catch the fish by descending 60 feet.
To explain this
We will take the help of Integers by representing it on the number line.
We will represent sea level by Integer 0.
⇒60 feet above sea level= +60
⇒60 feet Below = -60
Now,⇒ 60 + (-60)=0
⇒Also, 60 and -60 are additive inverses of each other, when added together yield additive Identity which is "0" for group of Integers.
→0=Sea Level

Answer:
The required probability is or 0.125
Step-by-step explanation:
Consider the provided information.
The spinner is spin twice and we want the sum should be 5.
We can get 5 if first spin gives us 2 and second spin gives 3.
Or we can get 5 if first spin gives us 3 and second spin gives 2.
There are 8 section out off which Three sections numbered 1, one section numbered 2, and four sections numbered 3.
The probability of getting 2 is
The probability of getting 3 is
Now, the probability that the sum of the two spins will be five is:
Hence, the required probability is or 0.125
