Answer:
43,758 different swimmer squad
Step-by-step explanation:
Given;
Total Number of athletes n = 18
Number of athletes needed to be selected r = 8
For this case, the coach need to select 8 players from a total of 18 athletes with no particular order. So, this is a combination case since the order of selection is not relevant.
The number of different swimmer squads the coach could select is;
S = nCr
nCr = n!/(r!×(n-r)!)
Substituting the values of n and r;
S = 18C8
S = 18!÷(8! × (18-8)!)
S = 18! ÷ (8!×10!)
S = 43,758
Therefore, he can select 43,758 possible different squads
So find the diameter which is the radius times 2
So 3x2= 6
6x 3.14(Pi)
=18.84 which a full circle and now divide by two
9.42 is the area of semi circle
Answer:
see below
Step-by-step explanation:
find common denominator and add the fractions in numerator and denominator:
1/x² + 2/y = y+2x²/x²y
5/x -6/y² =5y² -6x/xy²
(y+2x²)/x²y / (5y²-6x)/xy² change into multiplication
(y+2x²)/x²y * xy²/(5y²-6x)
simplify
y(y+2x²)/ x(5y²-6x)
Answer:
1 and 2 are the answers i think
Step-by-step explanation:
Sounds simple to me but may be misleading, I can't see a trick.
I think all you do is multiply each by 30.
So answer is 45ft X 37.5ft
Hope it's correct. I'd appreciate if you could let me know. Thks..
