Answer: There are 880 chairs in all.
Step-by-step explanation:
Number of rows of chairs = 40
Number of chairs in each row = 22
For total number of chairs we must do the product of number of rows of chairs and number of chairs in each row.
Total number of chairs is given by
So, there are 880 chairs in all .
Answer:
16 sqrt(30)
2√20 × 4√6
Multiply
2*4 sqrt(20*6)
8 sqrt(120)
Simplifying
8 sqrt(4 *30)
We know sqrt(ab) = sqrt(a) sqrt(b)
8 sqrt(4) sqrt(30)
8 *2* sqrt(30)
105
By the chain rule,
Observe that
Then
