In generation 8 it would have 34 relatives, and in generation 9 it would have 55 relatives.
In the Fibonacci sequence, each term is found by adding the two previous terms together. For generation 8, we would add generation 7 (21) and generation 6 (13); 21+13 = 34. For generation 9, we would add generation 8 (34) and generation 7 (21); 34 + 21 = 55.
Answer:
The answer is 10/143
Step-by-step explanation:
Given :
A sailor is 30 m above the water in the crow's nest on a sailboat.
The sailor encounters an orca surface at an angle of depression of 15 degrees.
The crows nest is 20 m horizontally from the bow (front) of the boat.
To Find :
How far in front of the boat is the orca.
Solution :
Let, distance of boat front from the crow's nest is x.
So,

Hence, this is the required solution.
I'm going to assume you mean:
13 * (3/4) + x = 7 * (1/4)
Let's go ahead and simplify the right side.
7 * (1/4) = 1.75
So now we have:
13 * (3/4) + x = 1.75
Now let's take care of the right side. Multiplication before addition.
13 * (3/4) = 9.75
9.75 + x = 1.75
To isolate x, we subtract 9.75 from both sides.
9.75 - 9.75 + x = 1.75 - 9.75
x = -8
Hopefully I spaced this well. \('-')/
