Which statements are true about a decagonal (10-sided) pyramid? Check all that apply.
It has one face that is a decagon.
It has two faces that are decagons.
It has 11 faces.
It has 20 edges.
It has 20 vertices.
Answer:
Step-by-step explanation:
The specifications of a decagonal pyramid would be the following
It has one face that is a decagon.
35 diagonals in the base.
10 isosceles triangles as faces above the base
11 vertices - 10 in the base and 1 at the top
20 edges - 10 in the base and 10 above the base
This can all be seen in the picture of the decagonal pyramid below. The only decagonal face is on the base of the pyramid as the top is a vertice where all of the triangles meet.

Answer:
I got 17.99 inches
Answer:
18 ft (it's correct)
Step-by-step explanation:
formula for volume: volume = [tex]\pi r^2h[/tex]
plug in the values that they give you
5,652 = [tex]\pi 10^2h[/tex]
simplify
5,652 = 100pi h
solve for h
[tex]\frac{5652}{100\pi } = h[/tex]
h = 18 (rounded)

Use similar triangles to solve for the missing lengths below.
If you know how to work this out please help:)
Answer:
x = 14
y = 18
Step-by-step explanation:
By the property of similar triangles,
If two triangles are similar their corresponding sides will be proportional.
[tex]\frac{AB}{EF}= \frac{AC}{GE}[/tex]
[tex]\frac{5}{10}=\frac{7}{x}[/tex]
x = [tex]\frac{70}{5}[/tex]
x = 14
Similarly, [tex]\frac{AB}{EF}= \frac{CB}{GF}[/tex]
[tex]\frac{5}{10}=\frac{9}{y}[/tex]
y = [tex]\frac{90}{5}[/tex]
y = 18

The automobile insurance
company receives 18 calls in 6
hours. How many calls do they
received in 11 hours?
Answer:
33
Step-by-step explanation:
An easy way to do this is create a proportion.
[tex]\frac{18}{6} = \frac{x}{11}[/tex]
Keep in mind you could also write this equation as [tex]\frac{6}{18} = \frac{11}{x}[/tex] as long as you are consistent. The number of calls should be in the same place and the hours should also be in the same place (either the numerator or denominator).
Next, just cross multiply.
6x = (18)(11)
6x = 198
x = 33 calls
Answer:
They would get 33 calls!

Answer:
5500 ml or 5.5 liters
Step-by-step explanation:
First, we should note that there are 1000 milliliters in 1 liter of liquid.
So, in milliliters, Peter filled three containers with 1500 ml, 750ml, and 2250 ml with 1000ml left over.
To find the total amount, we find the sum of all the milliliters:
1500 + 750 + 2250 + 1000 = 5500 ml
Again, we know that there are 1000 milliliters in 1 liter of liquid, so:
[tex]\frac{5500}{1000}[/tex] = 5.5 liters
