The volume of the regular pyramid is V = 216 units³
What is the volume of a pyramid?The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.
Volume of Pyramid = ( 1/3 )a²H
Given data ,
Let the volume of the pyramid be represented as V
Now , the equation will be
Let the height of the pyramid be H = 8 units
Let the side length of the pyramid a = 9 units
Now , Volume of Pyramid = ( 1/3 )a²H
On simplifying , we get
The volume of pyramid V = ( 1/3 ) ( 9 )² ( 8 )
The volume of pyramid V = ( 27 ) ( 8 )
The volume of pyramid V = 216 units³
Hence , the volume of the pyramid is 216 units³

The Jones family eats 2/3 of a packet of biscuits every day. How long will 27 packets last the family?
Answers
Answer:
40 1/2 days
Step-by-step explanation:
Quantity of biscuits the Jones eats daily = 2/3 of a packet
Total packets of biscuits = 27 packets
How long will 27 packets last the family?
= Total packets of biscuits / daily intake of biscuits of the Jones
= 27 ÷ 2/3
= 27 × 3/2
= 81 / 2
= 40 1/2 days
which of the following rational functions is graphed below?
Answers
Thank you for your time
The rational function graphed below is: [tex]\(f(x) = \frac{1}{(x + 3)(x - 3)}\)[/tex]
To determine the rational function graphed below, let's analyze the key features of the graph.
The graph appears to have two vertical asymptotes at [tex]\(x = -3\)[/tex] and [tex]\(x = 3\)[/tex] since the denominator [tex]\((x + 3)(x - 3)\)[/tex] becomes zero at those points, and division by zero is not defined. Vertical asymptotes are represented by vertical lines that the graph approaches but never touches.
The graph also seems to cross the x-axis at [tex]\(x = -3\)[/tex] and [tex]\(x = 3\)[/tex] since the numerator 1 is nonzero at those points, causing the function to have y-intercepts at those locations.
Furthermore, the graph appears to be symmetrical with respect to the vertical line x = 0 because the rational function is an even function. This is evident from the fact that the terms [tex]\((x + 3)\) and \((x - 3)\)[/tex] in the denominator are identical except for the sign. Therefore, the function has symmetry about the y-axis.
Considering all these characteristics, the rational function that matches the given graph is:
[tex]\(f(x) = \frac{1}{(x + 3)(x - 3)}\)[/tex].
This function has vertical asymptotes at [tex]\(x = -3\) and \(x = 3\)[/tex], crosses the x-axis at [tex]\(x = -3\) and \(x = 3\)[/tex], and is symmetric with respect to the y-axis. The graph should resemble a hyperbola centered at the origin.

Translate the sentence into an inequality. Twice the difference of a number and 2 is at least 21. Whoever is correct gets brainliest!
Answers
Answer:
2(c-2) >= 21
Step-by-step explanation:
At least means the smallest number must be, so the symbol is greater than or equal to for 21 to be the smallest possible number.
For twice the difference of a number and 2, we need the difference first, then we multiply by 2, hence 2(c-2).
Combining all of our previous information, 2(c-2) >= 21.

A pilot flew a 400-mile flight in 2.5 hours flying into the wind. Flying the same rate and with the same wind speed, the return trip took only 2 hours, with a tailwind.
What was the speed of the wind?
Answers
Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.

Answers
Answer:
Check the solution below
Step-by-step explanation:
2) Given the equation
x +y =5... 1 and
x-y =3 ... 2
Add both equations
x+x = 5+3
2x = 8
x = 8/2
x = 4
Substitute x = 4 into 1:
From 1: x+y = 5
4+y= 5
y = 5-4
y = 1
3) Given
x+3y =15 ... 1
2x+7y=19 .... 2
From 2: x = 15-3y
Substitute into 2
2(15-3y)+7y = 19
30-6y+7y = 19
30+y = 19
y = 19-30
y = -11
Substitute y=-11 into x = 15-3y
x =15-3(-11)
x = 15+33
x = 48
The solution set is (48, -11)
4) given
x/2 +y/3 =0 and x+2y=1
From 1
(3x+2y)/6 = 0
3x+2y = 0.. 3
x+2y= 1... 4
From 4: x = 1-2y
Substutute
3(1-2y) +2y = 0
3-6y+2y = 0
3 -4y = 0
4y = 3
y = 3/4
Since x = 1-2y
x = 1-2(3/4)
x = 1-3/2
x= -1/2
The solution set is (-1/2, 3/4)
5) Given
5.x=1/2 and y =x +1 then solution is
We already know the vkue of x
Get y
y= x+1
y = 1/2 + 1
y = 3/2
Hence the solution set is (1/2, 3/2)
6) Given
3x +y =5 and x -3y =5
From 3; x = 5+3y
Substitute into 1;
3(5+3y)+y = 5
15+9y+y = 5
10y = 5-15
10y =-10
y = -1
Get x;
x = 5+3y
x = 5+3(-1)
x = 5-3
x = 2
Hence two solution set is (2,-1)
