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.
Therefore, there will be 11 tiles in 7th row.
Answer:
Step 1: Find out what 10 to the 5th power is equal to. it = 100,000
Step 2: Multiply 100,000 by 10
Step 3: your answer = 1,000,000

Step-by-step explanation:
1. Create a ratio of cows to days
7:30
*NOTE: The more cows, the less time it will take
2. Multiply 7 by 3 and divide 30 by 3
You would get 21 : 10
3. You have the answer!! :D
It will 10 days for 21 cows to graze the same plot of land.
Hope this helps :)
Have a nice day!
