A company make concrete bricks shaped like rectangular prisms.

1 answer:

3 0

Each brick contains 10*9*4=360 inches cubed. Since 1 brick = 360in³, we want to know how much 360in³ goes into 18000in³ (or how many bricks go into 18000in³). To do this, we simply divide 18000in³ by 360in³ to get 50 bricks

Line AB passes through points A(-6,6) and B(12,3). If the equations of the line is written in slope-intercept form, y=me+b then

KIM [24]

Use the previous given coordinates to solve for B.
Y=mx+b,
(3)=1/6(12)+b
3= 2+b
3-2=b
1=b
