A hexagonal pyramid has a volume of 144 cubic millimeters and a height of 4 millimeters. What is the area of the base of the pyramid? (Hint: Label the parts you know. Draw a picture if necessary)
This is confusing T^T
Answer:
The area of the base of the pyramid is 109.2 mm.
Step-by-step explanation:
The area of the base of a hexagonal pyramid is given by the area of a hexagon:
[tex] A_{b} = \frac{P*a}{2} [/tex]
Where:
P: is the perimeter
a: is the apothem
We need to find the perimeter and the apothem.
The perimeter is equal to:
[tex] P = 6*s [/tex]
Where:
s: is the side of the pyramid
And the apothem is:
[tex] a = \frac{\sqrt{3}}{2}*s [/tex]
So, to calculate the apothem and the perimeter we need to calculate the side of the pyramid. We can find it from the volume of the pyramid:
[tex] V = \frac{\sqrt{3}}{2}*h*s^{2} [/tex]
Where:
h: is the height = 4 mm
V: is the volume = 144 mm³
Then, the side is:
[tex] s = \sqrt{\frac{2V}{\sqrt{3}*h}} = \sqrt{\frac{2*144}{\sqrt{3}*4}} = 6.5 mm [/tex]
Now, we can find the perimeter and the apothem.
[tex] a = \frac{\sqrt{3}}{2}*s = \frac{\sqrt{3}}{2}*6.5 = 5.6 mm [/tex]
[tex] P = 6*s = 6*6.5 = 39 mm [/tex]
Finally, the area is:
[tex] A_{b} = \frac{P*a}{2} = \frac{39*5.6}{2} = 109.2 mm^{2} [/tex]
Therefore, the area of the base of the pyramid is around 109 mm.
I hope it helps you!

Braden has m muffins. He splits them evenly among 4 boxes. Write an expression that shows how many muffins are in each box.
Answer:
[tex]\frac{m}{4}[/tex]
Step-by-step explanation:
Hi there,
We know that there are a certain number of muffins represented by m. Since the problem states that it is split evenly into four boxes, we can write the expression: [tex]\frac{m}{4}[/tex]. We use division since the total is split up into even groups.
Hope this answer helps. Feel free to ask questions.

30.2832 m^2 or 26(pi) m^2
Step-by-step explanation:
There are three different shapes (right triangle, rectangle, and half-circle). To find the area of the whole you find the area of all of these things then add them.
Triangle: (axb/2)
The first thing we must do is determine the lengths of the triangle.a: Because the diameter of the circle directly across from the triangle we can use this as side ab: To find be we take 10-2 because the 2 is what is used for the rectangle making the 8 what is left over for our side b(axb)/2 = (4x8)/2 = 32/2 = 16 m^2Rectangle: (lxw)
The first thing we will do is confirm the length and width of the rectanglel: The diameter is the length of the rectangle l=4w: Because the top portion of the area meets at the point where the triangle and rectangle converge the width is 2lxw = 4x2 = 8 m^2Half-Circle: {(pi/2)(r)^2
r: The only variable we need is the radius which is just half of the diameter. Therefore r=2{(pi/2)(r)^2} = {(pi/2)(2)^2} = {(pi/2)(4)} = 2(pi) = 6.2832The Area of the Whole:
Triangle: 16 m^2Rectangle: 8 m^2Half-Circle: 2(pi) or 6.2832 m^216+8+2(pi) = 26(pi) m^2 OR 16+8+6.2832 = 30.2832 m^2Name at least two independent variables that could result in a change in a monthly electric bill

Answer:
1. The amount of time you keep your porch light on.
2. The temperature you keep your air conditioner at.
Step-by-step explanation:
Porch Light Time Example:
The light does not turn on or off based on the bill, thus its independent, but the bill is effected by the amount of time the light is on thus dependent.
You keep your porch light on for 24 hours a day for 1 month, that month your electricity bill is $50.
Next month you keep your porch light on for 12 hours a day and your electricity bill is $40.
Air Conditioner Temp Example:
The thermostat temperature is not effected by the bill, thus its independent, but the bill is effected by the thermostat, thus dependent.
You set your thermostat to 70 degrees for 1 month, that month your electricity bill is $50.
Next month you set your thermostat to 75 degrees for 1 month, that month your electricity bill is $40.

Isabella went to the salon and was charged $72.60 for a cut and color. She added 20% to the cost as a tip. If there is an 8% sales tax added to the original cost of the service, how much did she pay in total?
The total cost of the service paid by Isabella is given by the equation
A = $ 92.93
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total amount paid by Isabella for the services be A
Now , the equation will be
The cost of the service = $ 72.60
The percentage Isabella added as a tip = 20 %
So , the cost after the tip = 72.60 + ( 20/100 ) x 72.60
On simplifying the equation , we get
The cost after the tip = 72.60 + 14.52
The cost after the tip = $ 87.12
Now , the sales tax percentage = 8 % on the cost of service
Substituting the values in the equation , we get
Sales tax cost of the service = ( 8/100 ) x 72.60
On simplifying the equation , we get
Sales tax cost of the service = $ 5.808
Now ,
The total cost of the service A = cost after the tip + Sales tax cost of the service
The total cost of the service A = 87.12 + 5.808
The total cost of the service A = $ 92.928
The total cost of the service A = $ 92.93
Therefore , the value of A is $ 92.93
Hence , The total cost of the service is $ 92.93

Please help with this! I was having problems with the answer and I just wanted to know if I was right.
Answer:
108 degrees
Step-by-step explanation:
By the Exterior Angle Theorem:
(2x + 1) + 63 = 5x -2
2x + 64 = 5x - 2
66 = 3x
22 = x
Now, we can plug the value of x back into the expression that represents the exterior angle to find the measure of the exterior angle:
5(22) - 2
110 - 2
108
The answer is 108 degrees. (I'm sorry your question was answered so late; I hope you got the right answer when you solved it!)
