What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent

Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches

Based on its number of terms, what is the<br><br> polynomial r3-r2 +9r called?

Arte-miy333 [17]

Given:

The polynomial is

$r^3-r^2+9r$

To find:

Based on its number of terms name for the given polynomial.

Solution:

We have,

$r^3-r^2+9r$

Here, number of terms is 3.

Any polynomial with three terms is known as trinomial.

Therefore, based on its number of terms the given polynomial $r^3-r^2+9r$ is called a trinomial.

Let x and y be any numbers at all with x ≤ y. Show that the number of integers between x and y is [y] - [x] +1.That is show that

ddd [48]

Answer:

the explanation is given below.

Step-by-step explanation:

Here what is applied is assumption of range of values of number from say 1 - 100

In total, i stopped at 100 on the dot.

from this, the lowest number is 1 and the highest number is 100

hence the range of the numbers = Difference between Highest and Lowest

range = 100 - 1 = 99, the 99 gotten as the range is indicative that a number has been missing.

In order to make up the 100, an integer is added to the difference = 99, i.e 99 is added to 1 to make up the 100.

Furthermore, if 0 is exclusively out when numbers are counted up 100 with 0 inclusive, in such case, the first and last number are excluded from the counting. as such the integers will be {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.........., 99} since both 0 and 100 are not included.

Here, if we try to get the range = highest - lowest = 99 - 1 = 98, it implies that to make up the 99, an integer is added to the result of the difference = 98+1 = 99

As such, the number of integers between two numbers is the difference between the highest and the lowest number plus 1 i.e highest - lowest + 1 = y - x +1 = (the floor of y) - ( the ceiling of x) + 1
