Answer: correct option is B.
Answer:

Step-by-step explanation:
as if we form an imaginary triangle with this line as hypotenuse
we get
- base = 3 units
- perpendicular = 4 units
using Pythagoras theorem:-
hyponteuse ² = perpendicular ² + base²
hyp² = 4² + 3²
hyp² = 16 + 9

hyp = 5 units

A. -6/7
Because:
(2,6) (8,-1)
(x1,y1) (x2,y2)
x1 = 2. Y1=6. X2=8. Y2= -1.
Equation for slope is m = y2-y1
x2-x1
-1-6 = -7
8-2=6
Each story should be<span> Generally around 10 feet (</span>3 m<span>) total; So that means a </span>ten story building should be around 100 feet.
1254 i believe because 1000 is 1 thousand, 2 hundreds, 1 more tens block than ones block is 5 because there are 4 ones blocks
