The answer is 16 because u need to subtract the largest and the lowest
Answer:
Ishaan is 49 years old.
Step-by-step explanation:
Let the present age of Christopher be 'C'.
Let the present age of Ishaan be 'I'.
From the given data, we can form equations which will help us solve the problem.
Christopher is 20 years younger than Ishaan. This means:
C = I - 20 . . . (1)
Fourteen years ago, Ishaan would have been (I -14) years old and Christopher (C - 14) years old.
From the data, I - 14 = 3(C - 14) . . . (2)
Substituting the value of C in Equation 2, we get:
I - 14 = 3(I - 20 - 14)
⇒ I - 14 = 3(I - 34)
⇒ I - 14 = 3I - 112
⇒ 2I = 112 + 14 = 98
⇒ I = 49
So, Ishaan is 49 years old.

Step-by-step explanation:
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.

Answer: Choice C</h3>
The surface area of the pyramid is multiplied by 100.
======================================================
Explanation:
Consider a square that is 3 by 3. Its area is 3*3 = 9.
Then we'll multiply each dimension by 10 to get a 30 by 30 square. The new larger area is 30*30 = 900. The jump from the old area (9) to the new area (900) is "times 100". We can write 100 as 10^2, where the base of that exponential is the scale factor 10.
This idea can apply to any surface area and not just squares. This is why the surface area of the enlarged pyramid is 100 times that of the original pyramid.
new surface area = 100*(old surface area)
