about 42.8 because 898 divided by 21 gives you 42.76
Answer:
13)
Line A - slope/constant of proportionality = 5/2
Line B - slope/constant of proportionality = 2/3
14)
unit rate = 3/2 or 1.5
The unit rate, 3/2, is greater than line B's unit rate but is less than line A's unit rate.
Step-by-step explanation:
To find the constant of proportionality for question 13 you use the graph. k = y/x so you find the point at (4, 10) and you go up 10 (y) and over 4 (x). So now you have 10/4 and then you simplify to 5/2. Use the same method for line B to find the slope. Now for question 14 you subtract 10 - 5 to get 5 which is your x and 15- 7.5 to get 7.5 which is the y. So this is now 7.5/5 (y/x) or 3/2. 3/2 is less than 5/2 and greater than 2/3.
Thank you so much!!! Hope this helps!!!
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:
26 in
Step-by-step explanation:
Perimeter is calculated by adding all of the outside side lengths.
11 + 7 + 4 + 4 = 26
