When you simplify the numerator and the denominator, you find they both have denominators of xy. So, the ratio of those is the ratio of their numerators.

Answer:
1.30 hours
Step-by-step explanation:
Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...
duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression
= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)
= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication
≈ 1.30 . . . . rounded to hundredth
The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

With a suitable calculator, this can all be done at once.
Step-by-step explanation:
Communicative property states that, in addition, integers added in any order will still give the same answer.
So in this question,
rather than first adding 8 + (-5), we add 8 + (-8)
We know that a number + its additive Inverse (opposite sign) is equal to zero
And we know any number added to zero is equal to the number.
So we can quickly find out that the sum is -5
