The library is located 1.8 miles west of callies 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

Use Pythagaras theorem :-

x^2 = 1.8^2 + 2.4^2 where a is distance required

x^2 = 9

x = 3 miles Answer

Let the distance be x

x² = 1.8² + 2.4²

x² = 9

x = √9

x = 3

The distance is 3 miles.

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
