Rainbow [258]

The minutes it takes him to run 10.5 miles is 180 minutes

<h3>How many minutes did it take him to run 10.5 miles?</h3>

The given parameters are

Speed = 3.5 miles per hour

Distance = 10.5 miles

The time is calculated as:

Time = Distance/Speed

So, we have

Time = 10.5 miles/3.5 miles per hour

Evaluate the quotient

Time = 3 hours

Convert to minutes

Time  = 180 minutes

Hence, the minutes it takes him to run 10.5 miles is 180 minutes

A square has a side that is (x-3) units long. If the area of the square is 126.5625 sq units, what is the value of x?
Kitty [74]

Answer:

14.25 units

Step-by-step explanation:

Area of a square= l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9

x^{2}-6x+9=126.5625

x^{2}-6x-117.5625

Solving the equation using quadratic equation then as attached

x=14.25 units

To prove

x-3=14.25-3= 11.25 units

area=11.25*11.25=126.5625 sq units
