A fraction expressed by a numerator and denominator
For this case, what you must do is add the area of each of the triangles to find the total area of the polygon.
We have then:
A = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
A = 16
Equivalently, as the area of each triangle is the same, then:
A = 2 * (8)
A = 16
Answer:
the area of the polygon is:
16
Option 3
An equation of the form y=ax+b, where y and x are variables, and a and b are constants, is called a linear equation.
The reason it is called linear is because the graph of the equation is a line.
The line passes through the origin only if b=0, as in our problem.
Any line (except vertical lines) represents a proportional relationship in that the change in y is proportional with the change in x. It is not a condition that the line passes through the origin.
In our specific case, y=(1/5)x, means that the change in y is always 1/5 of the change in x. That is, if x changes by 5 units, y changes by 1. If x changes by 10 units, y changes by 2, and so on.
So, the constant of proportionality is 1:5, or 0.2.
Answer:
(3.5, 4.5)
Step-by-step explanation:
The masses have a total margin of 0.5 kg, or ±0.25 kg.
The mass of the first parcel is 1.5 kg ± 0.25 kg.
The mass of the second parcel is 2.5 kg ± 0.25 kg.
The combined mass is:
(1.5 kg + 2.5 kg) ± (0.25 kg + 0.25 kg)
4 kg ± 0.5 kg
So the lower bound is 3.5 kg and the upper bound is 4.5 kg.
