How many edges does a solid with 11 faces and 11 vertices have?

Mathematics

Rzqust [24]3 years ago
8 0

Answer:

20

Step-by-step explanation:

Given: F = 11, C = 11, E=?

By Euler's formula, we have:

F + V - E = 2 \\  \therefore \: 11 + 11 - E = 2 \\  \therefore \:22 -  E = 2 \\  \therefore \:22 -  2 = E  \\  \huge \red{ \boxed{\therefore \: E = 20}}

Hence, the solid will have 20 edges.

Simplify 18-2[x + (x - 5)].<br> O8-4x<br> 28 - 4x<br> 28 - 2x
densk [106]

Answer:

28-4x

Step-by-step explanation:

Step 1: Open most inner bracket and simplify

=18-2(x+x-5)

=18-2(2x-5)

Step 2: Expand brackets by multiplying 2 in and simplify

=18-2(2x)-2(-5)

=18-4x+10

=28-4x

Therefore the answer is 28-4x

Is rolling a 3 standard doe and then rolling a sum greater than 4 when counting the next roll an independent event?
zhannawk [14.2K]

Answer:

False

Step-by-step explanation:

In this question, you roll 3 from the standard die and then add it with the next roll to see if the sums are greater than 4.

From this explanation you can see that you use the result from your first roll for the second event, so we can conclude that the event is dependent.  

Imagine if we change the result of the first roll into 5, without adding the second roll we can know that the sum will be greater than 4. The first event result will influence the second event, so it is a dependent event.
