Answer:

5.74

Step-by-step explanation:

fx=5(x+4)-6

f(19)=5(19+4)-6

19f=5(23)-6

19f=115-6

19f=109

f=109÷19

f=5.74 or 19 14/19

Someone please help me on this. Please help me. Please don’t put a link.

Given:

The figure of a triangle LMN.

P is the centroid of triangle LMN.

To find:

14. Find the value of PN if QN=30.

15. Find the value of PN if QN=9.

Solution:

We know that the centroid in the intersection of medians of a triangle and centroid divides each median in 2:1.

Since P is the centroid it means NQ is the median from vertex N. It means P divides the median NQ in 2:1. So, PN:PQ=2:1.

14. We have QN=30.

PN=\dfrac{2}{2+1}QN

PN=\dfrac{2}{3}(30)

PN=2(10)

PN=20

Therefore, the value of PN is 20 when QN=30.

15. We have QN=9.

PN=\dfrac{2}{2+1}QN

PN=\dfrac{2}{3}(9)

PN=2(3)

PN=6

Therefore, the value of PN is 6 when QN=9.

Nikitich [7]

Answer:

$320

Step-by-step explanation:

First, convert the percentage to a decimal.

4% = 0.04

Now, you have to multiply the price by the decimal to find his commission.

8000 * 0.04 = 320

He made a commission of $320.
