Answer:
60
Step-by-step explanation:
He needs to write 300*9 pages which is 2700
We know that he writes 45 pages a minute
his speed can be shown through the following equations
45x=pages typed
where x=minutes
so we set up our problem
45x=2700
we divide by 45 and get x=60
9.000 is the answer so 9 because 9.173 is part of a number or a unit.
Answer: The answer is 144.
Step-by-step explanation: Let 'a' be the first term and 'd' be the common difference of the given arithmetic progression (A.P.).
According to the given information, A.P. is {0, 4, 8, 12, 16, . . .}, i.e., a=0 and d=4.
The sum of first n terms is given by
So, the sum of first 9 terms is
Thus, the required sum is 144.
