Answer:
3rd
Step-by-step explanation:
A. -(a+5)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(a+5) * -1 = a+5
B. -(-x+31)
Apply the distributive property:
-(-x+31) becomes (- -x +31) which simplifies to (x+31)
multiply that by -1 to get -x+31
C. -(4x+12)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(4x+12) * -1 = 4x+12
Answer:
cant see the image
Step-by-step explanation:
The volume of each of The buckets is:
V1 = pi * r ^ 2 * h
Where,
r: radio
h: height
Substituting values we have:
V1 = 3.14 * (5/12) ^ 2 * (25/12)
V1 = 1.14 feet ^ 3
The volume of the warehouse is:
V2 = (100) * (50) * (20)
V2 = 100000 feet ^ 3
Then, the number of buckets of rocks she could store in a warehouse is:
N = (V2) / (V1)
N = 100000 / 1.14
N = 87719
Answer:
the number of buckets of rocks she could store in a warehouse is:
N = 87719
The answer would be 240,000
