Answer:
51 cm
Step-by-step explanation:
4,000/(3.14 · 5²)
4,000/(3.14 · 25)
4,000/78.5 = 50.95541401
We know that 1 lb = 16 oz
So lets convert the 20 lb to oz and then compare the two quantities in consistent units.
If 1 lb = 16 oz then 20 lb are equal to 20*16 oz, that is
20 lb = 20*16 oz = 320 oz
therefore,
320 oz are greater than 272 oz, or,
20 lb are greater that 272 oz
Answer:
The difference between the volume of the two spheres is 791.6m^3.
Step-by-step explanation:
V = 4(pi)(r^3/3)
Sphere 1:
V = 4(pi)(6^3/3)
Solve.
V = 4(pi)(216/3)
V = 4(pi)(72)
V = 4(226.2)
V = (904.8)
Sphere 1 Volume: 904.8m^3
Sphere 2:
V = 4(pi)(3^3/3)
V = 4(pi)(27/3)
V = 4(pi)(9)
V = 4(28.3)
V = 113.2
Sphere 2 Volume: 113.2m^3
Subtract.
904.8 - 113.2 = 791.6
Correct answer would be b. x-10. You can check this by writing out (x-10) and writing the other factor out. Then simplify (factor) out everything and you will get x^2 - 21x + 110.
Answer:
<h2>x = -4 ± 2√(3) </h2><h2 />
Step-by-step explanation:
Discriminant Δ = √(8²-4×(1)×(4)) = √(48) = √(4×12) = √(4)×√(12) = 2√(12)
then x = (-8 ± 2√(12))÷2 = -4 ±√(12) = -4 ±√(3×4) = -4 ± 2√(3)
