Eduardo counted ten seconds (y) between seeing lightning and hearing thunder, and he knew that the lightning was about 2 miles (
Fed [463]

Answer:

The equation for the variation is:

\frac{Miles}{thunder\,\,time }  =0.2\,\frac{mi}{s}

Step-by-step explanation:

The relationship is given by the quotient between the two variables: (1) distance of the storm, and (2) the number of seconds to hear the thunder. That is:

\frac{Miles}{thunder\,\,time } =\frac{2}{10} =0.2\,\frac{mi}{s}

Find the sum. Write your answer in simplest form. 3/7 + 2/3​
Delicious77 [7]

Answer:

1 2/21

Step-by-step explanation:

We start out with:

3/7 + 2/3

In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:

3/21 + 2/21

But what about the numerators? You do the same thing as before (multiplying by the other's denominator).  Now we have:

9/21 + 14/21

We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:

1 2/21!
