Answer:
(-1, -1/2)
Step-by-step explanation:
M= (Xa+Xb/2, Ya + Yb/2)
M= -11+9/2 , 0 + -1/2
M = -2/2, -1/2
M=(-1, -1/2)
so is it has 100 puzzles less than board games and you have 263 board games just subtract 263-100 which is 163. if it has 10 more action figures than puzzles and you have 163 puzzles you would add 10 to 163 which would give you 173 action figures.
163 puzzles and 173 action figures is the answer
If order doesn't matter (e.g. all the positions in the committee are essentially identical) then the number of possible choices is

Answer:
120 pounds
Step-by-step explanation:
Data provided in the question:
Force applied, F₁ = 15 pounds
Displacement by Force F₁, x₁ = 1 foot
At natural length of the spring total movement of the door = 8 feet
Now,
we know,
Force in spring, F = kx
where, k is the spring constant
Thus,
15 = k(1) ............(1)
now when the door travels half the distance x₂ =
= 4 feet
Therefore,
F₂ = k(4) ..........(2)
Dividing 2 by 1
we get

or

or
F = 15 × 4 = 60 pounds
Thus,
for 2 springs combined force applied = 2 × 60 pounds = 120 pounds
