Answer:
Step-by-step explanation:
G is the centeroid of the triangle. G splits AE in the ratio 2 : 1
AG : GE = 2 : 1
AG = 2x and GE = x
2x = 20
x = 20/2
x = 10
GE = 10 ; AG = 20
AE = 20+10 = 30
CG : GD = 2:1
CG = 2x and GD = x
2x = 10
x = 10/2
x = 5
GD = 5
BF = 30
BG : GF = 2 : 1
BG = 2x ; GF = x
BF = 30
BG + GF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
The biggest one is there it’s obvious.
Answer:
DE
Step-by-step explanation:
You can tell by the markings. Since there are two vertical markings it concludes that those sides are the same length.
Answer:
Step-by-step explanation:
Given
--- time (years)
--- amount
--- rate of interest
Required
The last 10 payments (x)
First, calculate the end of year 1 payment
Amount at end of year 1
Rewrite as:
Next, calculate the end of year 1 payment
Amount at end of year 2
Rewrite as:
We have been able to create a pattern:
So, the payment till the end of the 10th year is:
To calculate X (the last 10 payments), we make use of the following geometric series:
The amount to be paid is:
--- i.e. amount at the end of the 10th year * rate of 10 years
So, we have:
The geometric sum can be rewritten using the following formula:
In this case:
So, we have:
So, the equation becomes:
Solve for x
Approximate
The answer is to this question is 100
