mean would be adding them all up and dividing by how many there is mean median mode and range but the mean absolute deviation would be actually can't tell you cuz I don't know myself but you could probably look it up I wish you the best of luck
We can let the radius of the semi circles be r and x can be the length of the rectangle.
The perimeter will be Perimeter = 2x + 2pr = 1200
The area of the rectangle is Area = x(2r)
Once we solve the perimeter equation, you get x = 600.
Put this into the area equation and you get Area = (600 - pr)(2r)
The maximum then gives r = 95. 493 and area 57, 295.8
Dimensions
Height is twice the radius or 190.986. Find base use equation x = 600 - p(95.493) = 300.
This means dimensions are 300 by 190.986
One hour is 60 minutes. since you're looking for 30 minutes, do 40 x 30 and divide by 60.
Answer: 20 miles in 30 minutes
An irrational number is a real number that can't be written as a fraction: since all rational numbers (
) are real numbers (
), the irrational numbers are all elements in that don't belong to .
The rational numbers are closed with respect to sum and multiplication, which means that the sum/product of two rational numbers is a rational number.
Note that, of all the options, only 
is irrational, because the other options are
so they all can be written as fraction. This means that
are all rational numbers, because they are the multiplication of two rational numbers.
So, your only hope to get an irrational number is to multiply
Expression 2 works exactly in the same way, because everything we said about the product is true for the sum as well.
