Volume = width × height × length.
First let's concentrate on the rectangular prism. This has 4 for its height and 5 for its width so you do 4 × 5 (=20) × 10 (because the length of the rectangular prism is the same as the triangular prism, so we will use the length of the triangular one) = 200m³ for the rectangular one.
To work out the triangular one, it's the same, but whatever answer you get you divide it by 2 because a triangle is just a rectangle cut in half diagonally. Therefore, 3 × 5 (=15) × 10 = 150. Then divided by 2 = 75m³.
Total volume = volume of rectangular prism + triangular prism
Therefore total volume = 200 + 75 = 275m³.
The answer to the question is
Answer:
7x is the slope
Step-by-step explanation:
And the y intercept is 16
Answer:
y=-4x-25
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-3)/(-6-(-7))
m=-4/(-6+7)
m=-4/1
m=-4
y-y1=m(x-x1)
y-3=-4(x-(-7))
y-3=-4(x+7)
y=-4x-28+3
y=-4x-25
