Answer:
The perimeter of the figure as a function of the number of triangles is 
.
Step-by-step explanation:
According to the diagram, we get the following facts:
i) For one triangle (
), the total perimeter is (
).
ii) For two triangles (
), the total perimeter is (
)
iii) For three triangles (
), the total perimeter is (
)
iv) For four triangles (
), the total perimeter is (
)
From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is .
The Greates Common Factor (GCF) is: 1
Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
The irrational number that can be added to pi to get a rational sum is PI.
