The surface area of a shape is the area of each face added together.
Triangles
The area of a triangle is 1/2*w*h. So 1/2*6*8 = 24. We have two of these faces, so we'll add this twice.
Outer Rectangles
The area of a rectangle is w*h, so for these we'll do 9*20 = 180. These shapes are again duplicates, so we'll add them twice.
Center Rectangle
Again, we know the area of a rectangle is w*h, so 6*20 = 120. This is the only shape that isn't repeated.
Finally, we need to add the areas of the shapes up.
24 + 24 + 180 + 180 + 120 = 528
Therefore the surface area of the net is 528 cm^2.
Answer:
They are already in order. Just connect them.
Answer:
C) Linear
Step-by-step explanation:
We can see from the plot that the data approach a straight line.
This means we can draw a line of best fit through this data and it should hit several data points; thus the answer is linear.
The answer is ". d."

Answer:
C
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
Therefore, the decimal number 0.00067 written in scientific notation is 6.7 × 10-4.
