Answer:
Step-by-step explanation:
For this exercise is necessary to remember the following formula:
Where "V" is the speed, "d" is the distance and "t" is the time.
In this case you must solve for the time, then:
Based on the information provided in the exercise, you can identify that:
Therefore, knowing this, you can make the substitution into the formula .
Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:
The given trinagle is a right angle triangle. let the missing side be x. To find x, we would apply the pythagorean theorem which is expressed as
hypotenuse^2 = one leg^2 + other leg^2
From the triangle,
hypotenuse = 14
one leg = 9
other leg = x
Thus, we have
To the nearest tenth, the length of the third side is 10.7
