Answer:
B) Stan made a mistake in step one.
Step-by-step explanation:
B) Stan made a mistake in step one.
When he multiplied 8(n+20), he should have gotten 8n+160, not 8n+20.
The height of the pile is 150.7 mm, and the volume is V = 6,830,477.5 mm³.
<h3>
How high will be the pile of papers?</h3>
We know that each paper is 0.55mm thick, then if we pile 274 of these, the height of the pile will be:
H = 0.55mm*274 = 150.7mm
Now we want to get the volume of the pile of paper. Remember that for a rectangular prism of height H, width W, and length L, the volume is:
V = H*W*L
In this case, we have:
- H = 150.7mm
- W = 18.5 cm = 185 mm
- L = 24.5 cm = 245 mm
Then the volume is:
V = (150.7mm)*(185 mm)*(245 mm) = 6,830,477.5 mm³

start inside the square root, replace X with -7.
-7 + 11 = 4
The number 4 comes out of the square root as 2.
Now there's a minus factor out there. Let's multiply this negative factor by 2 and get -2.
Now let's add -2 and -3.
Our output is -5.
The answer is A = 2 tenths
C = .2
