3. A hexagonal pyramid has the following measures:
base area = 41.5 cm2
slant height = 7cm
height = 6 cm
area of one lateral face = 14 cm?
a. Calculate the pyramid's volume. Show your work.
Include units.
b. Calculate the pyramid's surface area. Show your
work. Include units.
The surface area of the hexagonal pyramid is the amount of space on it
The volume of the pyramid is 83 cubic centimetersThe surface area is 125.5 square centimetersThe pyramid's volumeThe given parameters are:
base area = 41.5 cm^2slant height = 7cmheight = 6 cmarea of one lateral face = 14 cm^2This is calculated using:
V = 1/3Bh
So, we have:
V = 1/3 * 41.5 * 6
Evaluate the product
V = 83
Hence, the volume of the pyramid is 83 cubic centimeters
The pyramid's surface areaThis is calculated using:
S = L + B
Given that:
base area = 41.5 cm^2area of one lateral face = 14 cm^2A hexagonal pyramid has 6 lateral sides.
So, we have:
S = 6 * 14 + 41.5
Evaluate
S = 125.5
Hence, the surface area is 125.5 square centimeters

Of all the apartments in an apartment building, 20 percent are single bedroom apartments and 30 percent of the single bedroom apartments have balconies. If 28 single-bedroom apartments do not have balconies how many apartments are there in this apartment building?
Answer:
200
Step-by-step explanation:
Of the apartments in the building, 20% are singles and 70% of those do not have balconies.
That is, (0.20 × 0.70) = 0.14 of the building's apartments are singles without balconies. That is 28 apartments. If A is the number of apartments in the building, this means
0.14A = 28
A = 200 . . . . . divide by 0.14
There are 200 apartments in the building.

In the figure, ABCD is a rhombus.BG and DCG are straight lines
Find CAD
Find ACG
Answer:
Below in bold.
Step-by-step explanation:
1) as ABCD is a rhombuc AC bisects < BAD and < BCD .
Therefore < CAD = 1/2 * 104 = 52 degrees.
2) < ACG = < ADC + < CAD ( External angle of triangle theorem)
Therfore < ACG = 76 + 52 = 128 degrees.
Why does 2pi radians equal 360 degrees?
Answer:
So there are 2 pi radians in one revolution and since there are also 360 degrees in one revolution, this gives us a way to convert from radians to degrees. 2 pi radians equals 360 degrees or you can divide both sides by 2 and use pi radians equals 180 degrees.

What is the answer?
Step-by-step explanation:
120° + 20° + x = 180° ( sum of interior angle. of triangle is 180°)
140° + x = 180°
x = 180° - 140°
x = 40°
Now
y + x = 180° ( supplementary angle)
y + 40° = 180°
y = 180° - 40°
y = 140°
The angle measure of y is 140°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
The three angles of a triangle are 120°, 20° and x.
And we know,
the sum of the interior angle of the triangle is 180°.
120° + 20° + x = 180°
140° + x = 180°
x = 180° - 140°
angle measure of x = 40°
Now:
Here, x and y are supplementary angles.
Supplementary angles are two angles whose measures add up to 180°
y + x = 180°
y + 40° = 180°
y = 180° - 40°
y = 140°
Therefore, the value of y is 140°.

Using proportions, it is found that it will take him at least 135 minutes to shovel the driveway at this rate.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, it takes 45 minutes to shovel 240 ft². How long does it take to showel 720 ft²? The rule of three is given by:
45 min - 240 ft²
n min - 720 ft²
Applying cross multiplication:
240n = 45 x 720
n = 45 x 720/240
n = 45 x 3
n = 135

The vertices of a rectangle are W(1,2), X(4,2), 7(4, -3), and Z(1, -3). Find the perimeter of the
rectangle. Use words, numbers, or models to justify your answer.
Answer:
16
Step-by-step explanation:
We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

Write the equation of a line of the table below.
Pls help will give brainliest
Answer:
slope: 5
y-intercept: 0
Equation: [tex]y=5x[/tex]
Step-by-step explanation:
First, lets find the slope.
Every time we have an increase in [tex]x[/tex], we have an increase in [tex]y[/tex].
To find that change, we will divide the changes in [tex]y[/tex] using two points.
I will be using the points [tex](1,5), (2,10)[/tex]
[tex]\frac{10-5}{2-1}[/tex]
[tex]=5/1[/tex]
[tex]=5[/tex]
Therefore, the slope is 5.
Next, lets find the y-intercept. The y-intercept is where the line goes through the y-axis.
We can go back 1 x-value (since when x = 1, y = 5)
Subtracting our slope (5) from the y-value for 1, we get:
[tex]y=0[/tex]
Therefore, the y-intercept is 0.
Finally, lets find the equation.
Linear equations are in the form [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.
Plugging those values in we get: [tex]y=5x+0[/tex]
Which will be simplified down to [tex]y=5x[/tex]
