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
Option A
<u>Answer:
</u>
The product of -4 and 8.1 is -32.4
<u>Solution:
</u>
When we multiply a negative number with a positive number we get the resultant product as a negative number.
Here we have to multiply - 4 which is a negative number and 8.1 which is a positive number.
To simplify the multiplication calculation we can write 8.1 as 8+0.1 and then multiply 4 with both 8 and 0.1
-4 
8.1 = -4 (8+0.1)
⇒ -4 8.1 = -4 8 – 4 0.1 [Multiplying 4 with 8 and 0.1]
⇒ -4 8.1= -32 - 0.4
⇒ -4 8.1= - 32.4
Thus the product of -4 and 8.1 is -32.4
Answer:
true
Step-by-step explanation:
It is true because no matter what numbers you plug into the equation b+3 has to be greater than a+2 so it has to be one ahead.
To find the greatest common factor, first find the largest evenly divisible number that you can take out in both numbers, in this case 15 and 25. Then find the greatest or highest number of each variable that you can evenly take out or divide in both terms, this is for a, b and c.
So GCF of 15 and 25 would be 5
GCF of a = a^1 or a
GCF of b = b^1 or b
GCF of c = c^1 or c
Put everything together to find the GCF.
GCF = 5abc.
