What’s the final horsepower when driving a car in denver (an elevation of 5,280 feet) that’s rated at 300 horsepower? a. 250.4 b. 271.5 c. 252.48 d. 271.28

The Answer is  C  252.48 horsepower

Step-by-step explanation:

To the get better understanding of answer above

First we have to understand that it is a rule of thumb that for every 1000 feet the horsepower reduces by 3 percent.

From the question the car horsepower is 300

 3 percent  of 300 is lost for 1000 feet

 x  percent of 300 is lost  for 5280 feet

 3 percent of 300  = (3 ÷ 100) × 300 =0.03

In term of the relationship between loss of horsepower and altitude

 0.03  = 1000  

    x     =   5280

  cross multiply

           = 252.48

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
