Choosing 3 cards from a deck of 52 cards:
In short, how many combinations there are in choosing 3 cards among 52 ?
⁵²C₃ = (52!) / (3!)(49!) → 22,100 combinations
Answer:
8x2y - 6x2 - 8xy2 - y2
Step-by-step explanation:
Equation at the end of step 1 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+(8x•(y2)))-3y2)
Step 2 :
Equation at the end of step 2 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-(3•(y2)))-((((x2)+(y2))+23xy2)-3y2)
Step 3 :
Equation at the end of step 3 :
(((((5•(x2))•y)-(5•(x2)))+(3y•(x2)))-3y2)-(x2+8xy2-2y2)
Step 4 :
Equation at the end of step 4 :
(((((5•(x2))•y)-(5•(x2)))+3x2y)-3y2)-(x2+8xy2-2y2)
Step 5 :
Equation at the end of step 5 :
(((((5•(x2))•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 6 :
Equation at the end of step 6 :
((((5x2•y)-5x2)+3x2y)-3y2)-(x2+8xy2-2y2)
Step 7 :
Final result :
8x2y - 6x2 - 8xy2 - y2
Answer:
30 gallons
Step-by-step explanation:
step 1 right it out
2 hour is 120 mins and 4 cups are poured per min
step 2 Equation time
so your equation should be
4/1=x/120
step 3 solve it out
1 times 120 is 120 is 4 times 120 is 480
but that is not the answer 480 is the amount of CUPS that are used for 2 hrs
so all u have to do is now convert
step 4 convert
16 cups are in 1 gal. so divide 480 by 16 and get 30 gal
x=30 gallons
