Answer:
0.14 lb . . . closest choice is 0.11 lb
Step-by-step explanation:
The inside and outside radii are 1/8 in and 3/8 in, respectively. Then the area of the top of the washer is ...
A = π(R² -r²) = π((3/8)² -(1/8)²) = π(9/64 -1/64) = π/8 . . . square inches
The height of the stack of 5 washers will be 5×(1/4 in) = 5/4 in. So, the volume of material in the stack of washers is ...
V = Bh = (π/8)(5/4) = 5π/32 . . . cubic inches
The weight of material is the product of volume and density, so is ...
W = (5π/32 in³)(0.285 lb/in³) ≈ 0.1399 lb ≈ 0.14 lb

<em>Comment on the question</em>
Since this answer does not correspond to any of the offered choices, we suggest you ask your teacher to work this out for you. We suspect they will have difficulty justifying any of the answer choices shown here. (0.11 lb corresponds to 4 washers, not 5.)

Answer:(0,0) (1,-1) (8,-2)
Step-by-step explanation:I hope this helps keep pushing on to greater grades
It's 7.3
To find the ratio divide 14.04 by 5.2
Then check another one, divide 21.87 by 2.7 and 19.87 by 2.7 to get the other two sides.
Answer:
p = 
Step-by-step explanation:
q=
- r÷ t using BODMAS
q = - (r/t)
q + r/t =
p=
