You have said that Brigitte is shorter than 5 feet. Translating your statement into rigorous mathematical terminology, we would write "Brigitte's height is less than 5 feet.". Then, using 'h' to represent Brigitte's height, and '<' to represent the words "less than", we can write the statement symbolically as [ h < 5 feet ].
They can be arranged 120 different ways
Answer:
8,246,160
Step-by-step explanation:
Population density
= people/area
Given
Population density of New York = 17,620 and
Area = 468 square mile
Therefore,
17620 = people /468
Cross multiply
People = 17620 x 468
= 8246160
There are 8,246,160 people in New York
Answer:
3769.92 ft
Step-by-step explanation:
The diameter of the wheel, d= 60 ft
We know the perimeter of the wheel is,
= πd
= 3.1416*60
= 188.496 ft
Wheel travel for 5 minutes. So the wheel travel,
= 5*60
= 300 sec
The wheel rotates in every 15 seconds. So the wheel rotates,
= 300/15
= 20 times
In one rotation, the wheel travels its perimeter. so is 5 minutes it travels,
= 188.496*20
= 3769.92 ft
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.
