Answer:
A car dealership needs $13050 to sell the car to earn the 45% profit if a car dealership buys a car for $9000.
Step-by-step explanation:
Car cost = $9000
Profit percentage = 45% profit
Thus,
Profit amount = 45% of 9000
                        = 45/100 × 9000
                        = 0.45 × 9000
                        = $4050
In order to determine how much a car dealership needs to sell the car to earn the 45% profit, all we need is to add the profit amount i.e. $4050, and the car cost i.e. $9000.
i.e.
Car cost + Profit amount = $9000 + $4050
                                          = $13050
Therefore, a car dealership needs $13050 to sell the car to earn the 45% profit if a car dealership buys s car for $9000.
 
        
             
        
        
        
Answer:
- a)  11, d) 25, e) 14, b) 25, c) 28, f) 33
Step-by-step explanation:
<h3>Given</h3>
- ΔBDF, with H is the centroid of BDF, DF = 50, CF = 42, and BH = 22
<h3>To find</h3>
<h3>Solution</h3>
As per definition of the centroid, the points C, E and G are midpoints of respective sides and the length of short and long distances from the centroid have ratio of 1/3 and 2/3 of median 
- a) HE =  1/2BH = 1/2(22) = 11
- d) DE =  1/2DF = 1/2(50) = 25
- e) CH =  1/3CF = 1/3(42) = 14
- b) EF =  DE = 25
- c) HF =  2/3CF = 2/3(42) = 28
- f) BE =BH + HE = 22 + 11 = 33
