Gary leaves school to go home. He walks 8 blocks north and then 14 blocks east. If Gary could walk in a straight line to the school, what is the exact distance between Gary and the school?

16.12 blocks

Step-by-step explanation:

Given that,

Gary walks 8 blocks north and then 14 blocks east.

We need to find the exact distance between Gary and the school. We can find it by using Pythagoras theorem as follows :

So, the exact distance between Gary and the school is 16.12 blocks.

-3, -2 and -1

Step-by-step explanation:

Given the inequality -3(1-z)<9

Expand

-3(1)-3z <9

-3-3z <9

Add 3 to both sides

-3-3z+3<9+3

-3z<12

Divide both sides by -3

-3z/-3 >12/-3

z > -4

The required solutions are values greater than -4 and they are -3, -2 and -1
