Answer:
11
Step-by-step explanation:
We have been given that tiles in each new row is 2 less than the row below it and the first roe has 23 tiles.
We can see that tiles in rows represents a arithmetic sequence. So we will use arithmetic sequence formula to find the number of tiles in 7th row.
, where
is nth term of sequence,
is first term of sequence and d is the common difference between consecutive terms.
Let us substitute our given values in above mentioned formula to find the 7th term of our arithmetic sequence.
![a_7=23-12](https://tex.z-dn.net/?f=a_7%3D23-12)
![a_7=11](https://tex.z-dn.net/?f=a_7%3D11)
Therefore, there will be 11 tiles in 7th row.
Answer:
1,500 rotations
Step-by-step explanation:
To answer this, divide 2.2 m into 3300 m. This results in 1500.
The wheels made 1,500 rotations each.
These things do not affect the direction of the inequality:<span>
1.Add (or subtract) a number from both sides.
2.Multiply (or divide) both sides by a positive number.
