Answer:
n=10
Step-by-step explanation:
The given equation is
...(1)
Let nth term is 2n.
We need to find the values of n.
It is clear that is sum of A.P., whose first term is 10 and common difference is 2.
Sum of A.P. is
where, a is first term and d is common difference.
Substitute a=10 and d=2 in the above formula.
...(2)
From (1) and (2), we get
Splitting middle term, we get
Since, n represents the number of terms so n cannot be a negative number, therefore number of term is 6.
Note: nth term and variable n both are different.
Sixth term is 20. So,
Therefore, the value of n is 10.
Answer:
Step-by-step explanation:
Let w represent width of the rope-off section.
We have been given that a manager needs to rope off a rectangular section for a private party the length of the section must be 7.6 m the manager can use no more than 28 m of the rope.
We will use perimeter of rectangle formula to solve our given problem. We know that perimeter of a rectangle is equal to 2 times the sum of length and width.
Upon substituting our given values, we will get:
Since the manager can use no more than 28 m of the rope, so perimeter of rope-off section should be less than or equal to 28 meters.
We can represent this information in an inequality as:
Therefore, our required inequality would be .
Let us find width as:
Therefore, the width of the rope-off section should be less than or equal to 6.4 meters.
