a boat salesperson earns a 2.5% commission on the sale of each boat Find the commision earned on a boat that sells for 18,500
marin [14]
100% = 1.0
2.5% = 0.025

So now we know the decimal that corresponds to 2.5%, so all we have to do is multiply the price of the boat by this value in order to find the commission earned:

18 500 x 0.025 = $462.50

C is the circumcenter of triangle PQR. PC = 3x + 7, RC = 5x - 15, & QC = 51 - x
SVETLANKA909090 [29]

Answer:

The value of PC is 40.

Step-by-step explanation:

Consider the complete question is " C is the circumcenter of triangle PQR. PC=3X-7 RC=5X-15 & QC= 51-X What does PC equal?"

All vertices or a triangle are equidistant from its circumcenter.

PC=RC=QC

RC=QC

5x-15=51-x

5x+x=51+15

6x=66

x=11

The value of x is 11.

We need to find the value of PC.

PC=3x+7

Substitute x=11 in the above equation.

PC=3(11)+7

PC=33+7

PC=40

Therefore, the value of PC is 40.
