Let's name the seats 1 through 120.
Occupy seat 2.
Leave 2 empty seats. You can't leave 3 empty seats because then the middle seat of the three empty seats is not adjacent to an occupied seat. You can leave only 2 seats empty. Seats 3 and 4 are empty.
Occupy seat 5.
Leave 2 empty seats. Seats 6 and 7 are empty.
Keep on going like this to the end, occupying 1 seat and leaving 2 seats empty.
Now we need to find the number of occupied seats.
Think of the entire row being divided into groups of 3 seats.
The middle seat of each group is occupied.
Since there are 120 seats in the row, there are 40 groups of 3 seats whose middle seat is occupied. There are 40 middle seats, so there are 40 occupied seats.
Answer: 40 seats
Answer:
U just need to guess it does not have to be exact just say like 200 bricks and u will get it right.
The volume formula of a sphere is 4/3 Pi R^3
To figure this out, we must cube the radius (multiply 3 times).
2 x 2 x 2 = 8 (4 x 2).
Now we must multiply 8 by 3.14
8 x 3.14 = 25.12
Since we have gotten those out of the way, we now have to multiply 25.12 by 4/3.
4/3 x 25.12 = 33.51
33.5 in ^3 is your answer since we used volume.
Hope this helps!
Answer: (-5,35)
Step-by-step explanation:
-7x=-5x+10
Get x on one side by adding 5x
-2x=10
Simplify by dividing by -2
X=-5
Substitute into y=-7x
Y=-7(-5)
Simplify
Y=35
