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:
i think its B
Step-by-step explanation:
Hey there!
f.8=8f
0.8f = 8f
SUBTRACT 8f to BOTH SIDES
0.8f - 8f = 8f - 8f
SIMPLIFY IT!
-7.2f = 0
DIVIDE -7.2 to BOTH SIDES
-7.2f/-7.2 = 0/-7.2
CANCEL out3 -7.2/-7.2 because it give you 1
KEEP: 0/-7.2 because it help solve for the f-value
NEW EQUATION: f = 0/-7.2
SIMPLIFY IT!
f = 0
Therefore, your answer is: f = 0
Good luck on your assignment and enjoy your day!

Dado :
Total de brinquedos:
Bonecas = 21
Carros Roy = 18
Figuras de ação = 15
Número total de brinquedos = (21 + 18 + 15) = 54 brinquedos
Número de brinquedos por prateleira = 18
Número de prateleiras:
Número total de brinquedos / número de brinquedos por prateleira
Número de prateleiras = 54/18
Número de prateleiras = 3
3 prateleiras estão na vitrine
Model of Statue of Liberty is 30.6 feet tall.
<u>Step-by-step explanation:</u>
Given the Statue of Liberty is 306 feet tall. If the model is 1/10 the actual size of the Statue of Liberty.
Actual size of the statue = 306
Model is 
of the actual size of the Statue of Liberty
Height of model = of the actual size
= * 306
= 30.6 feet
Model of Statue of Liberty is 30.6 feet tall.
