For part A, we will see that the distance is 7 units. For part B, the distance from Nina's house to the school to the grocery store is larger.
<h3>How to find the distances?</h3>
Remember that the distance between two points (a, b) and (c, d) is:
A) Her house is at (-4, 10), and her school is at (-4, 3), so the distance is:
The distance is 7 units.
B) In the first case, the distance between the school and the grocery store is:
So the total distance is 9 + 7 = 16
And the distance between the school and the community center is:
So the total distance is 6 + 7 = 13
So we can see that the total distance from Nina's house, to the school, to the grocery store is larger than the other.

Let
x--------> the degree of difficulty of the dive
we know that
1) The highest and the lowest scores are dropped
so
highest scores=
lowest scores=
the remaining scores=
2) Find the total of the remaining scores
3) The total of the remaining scores is multiplied by the degree of difficulty of the dive
so
4) This product is multiplied by .6 to determine the final score
therefore
the answer is
the degree of difficulty of the dive is
