Answer:
T31= 278
Step-by-step explanation:
formula is Tn=a +(n-1)d
T31= 8+(31-1)9
T31=8+(30)9
T31=8+270
T31=278
The correct answer is C. n is greater than or equal to 30
So essentially, we have a choice of :
2 reception halls
3 DJs
2 catering companies.
In order to find the number of arrangements, you need to multiply those : 2*3*2=12- So they have 12 arrangements.
why?
Imagine those 3 Djs- they are three arrangements.
Now, they can play in one or the other hall -so in total it's 3 Djs in one hall and 3 in the other -that's 6.
And all of those 6 possibilities can be catered by one or the other company- making the possibilities twice as many, so it's 12 in total!
Answer:
-1/4
Step-by-step explanation:
Answer = 50
Separate both into two different rectangles
Find the missing sides
Multiply (length x width)
Add the area of both the rectangles together
Example :
Top rectangle
10 - 6 = 4yd
4 x 8 = 32
Bottom rectangle
8 - 5 = 3yd
3 x 6 = 18
Area = 50
