Answer:
A perfect score on a test
Step-by-step explanation:
Since the score gets subtracted for each wrong answer, if x=0 then then nothing would get taken away from the initial 80
Answer:
Step-by-step explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³
Answer:
70 days
Step-by-step explanation:
that is the procedure above
Answer:
(-2, 1)
Step-by-step explanation:
Putting in -2 as an input basically means plugging in -2 in the place of x
So it would result in this
y = -3(-2) - 5
Remember that multiplying a negative number by another negative number results in a positive number
y = 6 - 5
y = 1
So we have
x = -2
y = -1
Making the answer (-2, 1)
I believe you are asking in how many ways they can sit. If so:
The 1st can sit anywhere: he has only 1 way to sit
The 2nd can sit in 11 ways, since one seat is already occupied
The 3rd can sit in 10 ways, since 2 seat are already occupied
The 4th can sit in 9 ways, since 3 seat are already occupied
The 5th can sit in 8 ways, since 4 seat are already occupied
--------------------------------------------------------------------------------
The 12th can sit in 1 way, since11 seat are already occupied
General formula for a circular table:
Number of ways they n persons can be seated: (n-1)!
and the 12 can be seated in (12-1)! = 11! = 39,916,800 ways.
This is called circular permutation
