Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the dimensions of the hexagon are not given.
I will assume that:
[tex]b = 6[/tex] --- base length
[tex]h = 8[/tex] --- height
First, we calculate the height (a) of each triangle that makes the hexagonal base
The formula to use is:
[tex]a^2 = b^2 - (\frac{b}{2})^2[/tex]
[tex]a^2 = 6^2 - (\frac{6}{2})^2[/tex]
[tex]a^2 = 6^2 - (3)^2[/tex]
[tex]a^2 = 36 - 9[/tex]
[tex]a^2 = 27[/tex]
Take positive square roots
[tex]a = \sqrt{27[/tex]
Expand
[tex]a = \sqrt{9*3[/tex]
Split
[tex]a = \sqrt{9}*\sqrt3[/tex]
[tex]a = 3\sqrt3[/tex]
So, we have:
[tex]Area = \frac{1}{2}ap[/tex]
Where
[tex]a = 3\sqrt3[/tex]
[tex]p =perimeter[/tex]
[tex]p = 6 * b[/tex] ---- 6 represents the sides of the hexagon
[tex]p = 6 * 6[/tex]
[tex]p = 36[/tex]
[tex]B= \frac{1}{2}ap[/tex]
[tex]B= \frac{1}{2} * 3\sqrt 3 * 36[/tex]
[tex]B= 3\sqrt 3 *18[/tex]
[tex]B = 54\sqrt 3[/tex]
[tex]h = 8[/tex]
Lastly, the volume is:
[tex]V = \frac{1}{3}Bh[/tex]
So:
[tex]V = \frac{1}{3} * 54\sqrt3 * 8[/tex]
[tex]V = 18\sqrt3 * 8[/tex]
[tex]V = 144\sqrt3[/tex]

The entire graph of the function f is shown in the figure below. Write the domain and range of f using interval notation.
Given y varies inversely as x, and y = 5 when x = 9. Write the inverse function
Answer:
y = 45/x
Step-by-step explanation:
Given y varies inversely as x, then;
y = k/x
If y = 5 when x = 9
5 = k/9
k = 5*9
k = 45
Substitute into the formula above;
y = k/x
y = 45/x
Hence the required inverse function is y = 45/x

if the radius is 3.345 what is the diameter
Answer:
6.69
Step-by-step explanation:
the radius is from the outside of the circle to the center and the diameter is completely through so you would times 3.345 by 2 to get 6.69 which is your diameter
Answer:
6.69
Step-by-step explanation:
radius is D/2
therefore, r =d/2
so therefore, 2×r=d
that is: 2×3.345 = 6.69

3x+2y=12 2x-3y=21 elimination please solve with answer and steps
Answer:
(6,-3)
or
x=6 y= -3
Step-by-step explanation:
Taking a quick look at this question we notice that we simply cannot add/subtract the two equations and eliminate a variable
What we can do is mulitply an equation to make the above true
let's try to get the first equation to have a 3y, and we can do this by multiplying it by 1.5 (this is legal because we do it to both sides)
So our new first equation is
1.5(3x+2y)=12*1.5
which simplifies to
4.5x+3y=18
We then add the two equatiosn
(4.5x+3y)+(2x-3y)=18+21
6.5x=39
x=6
Now that we know x we can plug that in and solve for y
3(6)+2y=12
18+2y=12
-6=2y
y= -3

Jake has a 34% batting average. If Jake gets up to bat 10 times in one game, what is the BEST estimate of how many times he will hit the ball?
Answer:
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls
Step-by-step explanation:
Batting average determine the % share of time the bat hit the ball.
Jake's probability of hitting a ball = 0.34
Jake plays 10 games.
Probability of hitting a ball in a game is
10 * 0.34 = 3.4
Approximately 3 times, Jake will be able to hit the ball in a game of 10 balls

Can someone explain to me what 8√42 ÷ 2√7 is?
Answer:
Step-by-step explanation:
8√42 ÷ 2√7 is 8√42/2√7 in a fraction form
you want to take the square root out of the denominator, and so you would multiply the denominator by the numerator and itself.
8√42/2√7 * 2√7/2√7 = 4√6
3x-8y=24
y=x-8
Please show
work
Answer:
3x - 8y = 24 --------(1)
y = x - 8 ---------(2)
substitute y in (1)
3x - 8( x - 8) = 24
3x - 8x + 64 = 24
-5x = 24 - 64
-5x = -40
5x = 40
x= 8
substitute x in (2)
y = 2 - 8
y = - 6
Answer:
x = 8, and y = 0
Step-by-step explanation:
We can solve this by taking y as (x-8), as it states there.
Since y is equal to x-8, we can rearrange the system of equations into one single equation.
We can multiply y by 8, as it shows in the first equation, which is something like 8x-64.
Since it is a negative 8 being multiplied by y, it would be the inverse of 8x-64, which is -8x+64.
We can now organize our equation here.
3x - 8x + 64 = 24.
We can use subtraction property of equality by subtracing 64 from both sides to get rid of it.
We will get something like:
3x - 8x + 64 - 64 = 24 - 64.
Simplify by solving like terms like the x value and the integers.
-5x = -40
Divide both sides with division property of equality:
-5/5x = -40/5
x = 8
We can then plug the 8 back into x, lets use the second equation because I'm lazy and it looks the easiest to solve for.
y = (8) - 8
y = 0
Therefore, x = 8, and y = 0.

an square has an area of 54 sq in . the length of each side is the same but not a whole number
Answer:
Answer = 13.5
Step-by-step explanation:
A square has 4 sides
54 / 4 = 13.5
The side of the square will be 7.34 inches.
What is an area?A square is a quadrilateral having all the sides equal to each other and the sum of the angles will be 360 degrees. The area is defined as the space occupied by the shape in a two-dimensional plane.
Given that a square has an area of 54 sq in . the length of each side is the same.
The side of the square will be calculated as below:-
Area of square = Side²
54 = Side²
Side = √54
Side = 7.34 inches.
Therefore, the side of the square will be 7.34 inches.

(a) Fill in the tavle below to complete the proability distrubution of X
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
(b) compute the mean of random variable x
Answer:
2.6
Step-by-step explanation:
Given :
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
Σp(x) = 1
Hence, 0.3 + 0.2 +? + 0.4 = 1
0.9 +? = 1
? = 1 - 0.9
? = 0.1
For the mean :
E(X) = ΣX*P(X)
(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)
0.3 + 0.4 + 0.3 + 1.6 = 2.6
Hence, the mean = 2.6
