The library is located 1.8 miles west of Callie’s house. The grocery store is located 2.4 miles south of the library. What is the length of a straight line between Callie’s house and the grocery store?

Answers

Answer 1
Answer: Hello!

A good way to solve this is by using the Pythagorean Theorem, where the distance between the grocery store and Callie's house is the hypotenuse of the triangle.

The two legs we are given, 1.8 and 2.4 will represent a and b in the Pythagorean Theorem. 

a²+b²=c²

First we have to find 1.8 and 2.4 squared. 

1.8²=3.24
2.4²=5.76

If we add these answers, we will get 9. This is c². But to find just c, we will undo the square by using the square root.

√9=3.

This means that the length of a straight line from Callie's house to the grocery store is 3 miles.

I hope this helps!

Order the following from greatest to least: -12,12,-19,1 and 1/2,5.....

Answers

-19, -12, 1/2, 1, 5, 12 ----> least to greatest
12, 5, 1, 1/2, -12, -19 ----> greatest to least

Do the same as the last one, starting with the largest negative number, and ending with the largest positive number.  The only difference in this case is that it is greatest to least.  I tend to go from least to greatest first and then flip it around to get greatest to least (:
