Lateral area of triangular prism = (a+b+c)h where a, b and c are the sides of the triangular base, h is the height.
LA= (a+b+c)h=
a=4
b=6
c=?
c=9
h=8
c=√6²+4²=√80 or approximately 9
you should get An Area= (4+6+√80)8
LA= 80+8√80
1: B
because a triangle angles all have to add up to 180
Complete question
To find 
, Beau found 
and 
. He said that since 5 is between 4 and 9, , is between 2 and 3. Beau thinks a good estimate for , is 
Is his estimate high or low? How do you know?
Answer:
The estimation is high because 5 is very close to 4 so will also be very close to 
which is lower than the estimate
In order to get a good estimate
The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them
i.e
From here we can see that lies between 2.2 and 2.3 but is closer to 2.2
So a good estimate for is 2.2
Step-by-step explanation:
25% or 2/4 and to win one game 50% or 1/2
Answer:
40951
Step-by-step explanation:
Using the principles of inclusion - Exclusion
Where C(n,r)=n!/(n-r)!r!
Total elements in the five sets including number repetition is given as (10000)×C(5, 1) =10000× 5!/(5-1)!1!=10000×5=50000
Total Number of elements in each pair including number repetition of sets is given as
=(1000) × C(5, 2) =10000
Number of elements in each triple of sets is given as
=(100) × C(5, 3) =1000
Number of elements in every four sets
=(10) × C(5, 4)=50
Number of elements in every one set
(1) × C(5, 5)=1
Therefore total number of unique elements=50000-10000+1000-50+1
=40951
