Y = -x/3 + b1 = -3/3 + b
substitute values of point1 = -1 + b
then reduce2 = b
add one to both sides y = -x/3 + 2
1 inch= 12 miles
Multiply 6 1/2 inches by total number of miles per 1 inch (12).
= 6 1/2 * 12
convert to improper fraction
= 13/2 * 12
multiply numerators
= (13*12)/2
multiply in parentheses
= 156/2
divide
= 78 miles

A rectangular prism is a cuboid so volume of cuboid is base area x height which is 5x5x12=300
volume of pyramid is 1/3 x base area x height = 5x5x6x1/3=50 thus volume outside pyramid and inside cuboid is 300-50=250
