Your answer is 142.86 milliseconds rounded to two decimal places.
As 1 second is equal to 1000 milliseconds, we can write the ratio 7:1000 to represent feet to milliseconds. We can then see that to get 1 foot, we just have to divide 1000 by 7, which gives us 142.8517, or 142.86 to two decimal places.
I hope this helps!
Answer: 14.96ft
Step-by-step explanation:
1. To solve this exercise you must apply the Pythagorean Theorem, which is:

Where
is the hypotenuse, and
and
are the other sides of the triangle.
2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.
2. Then, when you solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of the side of the rigth triangle is:
