For the first one (aka 7) you would write 10² wich is the same as 10×10 and so the answer is 100
For the second one (aka 8) you would write 3×3×3×3×3×3×3×3×3 and the answer is 486 square miles
There are 33 numbers between 1 and 100 divisible by 3, therefore the probability is 33% or 1/3

Answer:
The gradient of the line joining the points 
and 
is 
.
Step-by-step explanation:
The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line (
), that is:
(1)
If we know that and , then the gradient of the line is:
The gradient of the line joining the points and is .
A) A= 5000 x .0325 ( 31)
A= 5,037.50
.0325 = 3.25%
31 years 2021-1990 = 31
