John leaves his house to go to school. He walks 7 blocks north and then 4 blocks west. How far is John from his home?
round to nearest tenth

8.1 blocks from his house

Step-by-step explanation:

Draw it out,

You'll end up with a triangle with side a= 4 and b=7. What's left to find is the hypotenuse (the distance he is from his house).

Use pythagorean theorem (a^2 + b^2= C^2)

4^2 + 7^2= C^2

16 + 49 = C^2

65 = C^2

C= 8.06, round to 8.1
