Answer:
3000
Step-by-step explanation:
6000÷2=3000
Answer: D. 4
Step-by-step explanation:
In the given picture , we have given a triangle ΔMLN in which
ML= 4x and MN= x+3
∠L=∠N=50°
⇒ MN=ML [∵ Basically by Isosceles triangle property :sides opposite to equal angles of a triangle area equal.]
Subtract x from both sides , we get
Divide bothe sides by x , we get
1= x or x =1
Then, the length of MN
= x+3=1+3=4 units
Sum of the First n Terms of a Geometric Sequence
Given a geometric sequence (or series) with a first-term a1 and common ratio r, the sum of the first n terms is given by:
We are given the series:
Before calculating the required sum, we need to find the common ratio. It's defined as the division of two consecutive terms. For example, using the first two terms:
The first term is a1 =120. Now apply the formula:
Operating:
Calculating:
It would be 187.5 because 5 percent of 375 is 187.5
Answer:
C. always true
