Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
Opposite sides in a parallelogram are equal
So,
XY=WZ
3a-4=a+2
2a=6
a=3
XW=YZ
b+1=2b
b=1
Answer:
7
Step-by-step explanation:
7√5÷5
5/5= 1 then,
√1=1
hence 7(1)=7
Answer:
0.12
Step-by-step explanation:
12/100
The number of cups will be equal to 496.
<h3>What is arithmatic progression?</h3>
The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmatic progression
Here we have the data:-
The bottom row has 61 cups
If there are 16 total rows
The number of the cups will be calculated as:-
Here a1 is first term 1
an is last term 2
n is the total number of the rows
By putting the values in the question we will get:-
Hence the number of cups will be equal to 496.
