Answer:
Second option
Step-by-step explanation:
Answer:
B.)
Step-by-step explanation:
In the equation 3x+8
3 would be the number of marbles, since x is the weight of the marble, and 8 would be the weight of the empty bucket.
The equation is finding the weight of the bucket, therefore we need to add the weight of the bucket (8) and the weight of the marbles.
Answer:
No solution
Step-by-step explanation:
Find volume
volumecone=(1/3)(h)(pi)(r^2)
hemisphere is just a half sphere aka, 1/2 times volume of sphere so
hemisphere=(1/2)(4/3)(pi)(r^3)
fnd their volumes don't evaluate the true value till end, leav pi as pi
(or use pi key for graphing or scientific calculators)
cone
d/2=r
10/2=r=5
h=15
V=(1/3)(15)(pi)(5^2)
V=(5)(pi)(25)
V=125pi
hemisphere
V=(1/2)(4/3)(pi)(5.5^3)
V=(4/6)(pi)(166.375)
V=110.91666666666666666pi
which is bigger
125pi or 110.916666666666666666pi
125 pi
by how much?
125pi-110.91666666666666pi=14.08333333333pi
aprox pi=3.14
14.08333333*3.14=44.2217
rond
44
answer is CONICAL will hold 44 cubic feet more
