A car traveling at a constant speed travels 1000 ft in 12 seconds. how long in hours will it take to travel 175 miles?

artcher [175]

Answer:

3.08 hours

Step-by-step explanation:

We assume you're interested in the time in hours.

$175\text{ mi}\times\dfrac{12\text{ s}}{1000\text{ ft}}\times\dfrac{5280\text{ ft}}{1\text{ mi}}\times\dfrac{1\text{ h}}{3600\text{ s}}=\dfrac{175\times12\times5280}{1000\times3600}\text{ h}=\boxed{3.08\text{ h}}$

It will take 3.08 hours to travel 175 miles at that speed.

If x/y + y/x = -1 , ( x unequal y, y unequal 0) then the value of x^2 - y^2 is?

Maurinko [17]

Take your original equation $\frac{x}{y} +\frac{y}{x} =-1$

and multiply both sides by $xy$ to remove the fractions. You are left with

$x^2+y^2=-xy$

So, $x^2+y^2=-xy$

Update: There is no numerical answer that can be found without being given a value for either x or y

Solve:<br><br> (15/x)+(9x-7)/(x+2)=9

hram777 [196]

Answer:x=3

Step-by-step explanation:

D( x )

x+2 = 0

x = 0

x+2 = 0

x+2 = 0 // - 2

x = -2

x = 0

x in (-oo:-2) U (-2:0) U (0:+oo)

(9*x-7)/(x+2)+15/x = 9 // - 9

(9*x-7)/(x+2)+15/x-9 = 0

(x*(9*x-7))/(x*(x+2))+(15*(x+2))/(x*(x+2))+(-9*x*(x+2))/(x*(x+2)) = 0

x*(9*x-7)+15*(x+2)-9*x*(x+2) = 0

9*x^2-9*x^2+8*x-18*x+30 = 0

30-10*x = 0

(30-10*x)/(x*(x+2)) = 0

(30-10*x)/(x*(x+2)) = 0 // * x*(x+2)

30-10*x = 0

30-10*x = 0 // - 30

-10*x = -30 // : -10

x = -30/(-10)

x = 3
