Answer:
4 tribes. I don't even know how to do this question at all since it's way too difficult for me but this is an attempt.
Step-by-step explanation:
Let's use negative terms.
-2 = 6
-1 = 5
0 = 4
1 = 3
2 = 2
3 = 1
4 = 0
2 it’s two says the calculator
Data:
x y
16 4
32 16
48 36
Direct relation means that the ratio y / x is constant.
So, let's examine this ratio:
Ratio y / x
4/16 = 1/4
16/32 = 1/2
36/48 = 3/ 4
Given that the ratio y/x is not constant, the conclusion is that y does not vary directly with x.
Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
