Answer:
The height of the pyramid is <u>11.81</u>.
Step-by-step explanation:
Given:
A right rectangular pyramid has base dimensions of 23.2 by 17.0 and a volume of 1552.4.
Now, to find the pyramids height.
Let the height be 
Volume = 1552.4.
And the dimensions are:
Length (l) = 23.2.
Width (w) = 17.0.
Now, to get the height we put formula:



<em>Multiplying both sides by 3 we get:</em>

<em>Dividing both sides by 394.4 we get:</em>

.
Therefore, the height of the pyramid is 11.81.
6 divided by 4(3/5)
After multiplying the fraction we get 23/5
Dividing a fraction will result to multiplying
6 * 23/5
138/5 is the answer.

By Pythagoras theorem,

and it doesn't match
Irrational numbers cannot be classified as rational numbers. - EXPLANATION - both are different completely, according to as I think, and thus they cannot be inter-related. Irrational like - root2, root3, and all those that cannot be further solved completely. Their decimal representation is neither recurring nor ending e.g. 1.101001000100001000001.... and so on while rational number are consisting of whole numbers, integers, natural numbers, and all the constants and their decimal representation can be non ending but recurring.
5. d. Irrational numbers cannot be classified as rational numbers. - EXPLANATION - out of the options this one's correct. As I above said, all numbers as far as I know can be categorized into unreal and real numbers out of which real numbers consist of irrational and rational numbers while unreal numbers, I don't know as I have not been taught about them yet and neither do you have been, as I think so. All I know is that, as far as I have been taught, unreal number are not connected to real numbers.
6. Every real number is a rational number. - EXPLANATION - As I told you above, real numbers can also be irrational so this is false.
Hope this helps!
Answer:
Approximately 338,000 people live in that area.
Step-by-step explanation:
In order to solve this problem we first need to find the area of the region, since it's delimited by a 7 miles radius, then we can assume it's a circular region. The area of the circle can be calculated by the following formula:
area = pi*r² = 3.14*(7)² = 153.86 miles²
Since the region has a density of 2200 people per square mile and the density is given by the formula:
density = number of people / area
We can find the number of people living in the region by doing:
number of people = density*area
Applying the data from the problem:
number of people = 2200*(153.86) = 338,492 people
