Answer:
A. 0.0627
B. 8.4%
Step-by-step explanation:
You need to divide by 100 if you want to make the decimal to a percent. If you want to make a percent to a decimal then just multiply by 100.

Answer:
No, The answer should be 240
Step-by-step explanation:
- The first step to finding the Surface Area was done well and was right but you got confused when trying to add the area of each shape
- There is 3 Rectangles and 2 Traingles.
- Let's start with the area of the triangles. 1/2bh is the formula for finding area of Traingles. 1/2(4)(6) = 12. We have two Traingles so that would be 24.
- Now we have three rectangles with different lengths we need to calculate.
- Rectangle 1 = 12 * 8 = 96
- Rectangle 2 = 12 * 6 = 72
- Rectangle 3 = 12* 4 = 48
- 24+96+72+48 = 240.
- So, the surface area of the rectangular prisim is 240
Remark
You can just look at the graph to find out the y intercept. The y intercept is the point where x = 0. The point for the y intercept is (0,-2). So B is definitely wrong.
To get the slope, you can just use the x intercept which is (-3,0)
When y = 0, x = - 3. We need to do a little calculation to get the slope.
So far what we have is
y = mx - 2
y = 0
x = -3
0 = m(-3) - 2 Add 2 to both sides.
2 = m(-3) Divide by - 3
2/-3 = m
Now let's see what we have.
y = -2/3x - 2
C is the correct answer
