Step-by-step explanation:
so pretty much y= is the line that goes up and it has its own numbers right. the x= is the line that goes at the bottom right right
Answer:
c =4 4/9 minutes
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c where a and b is the time for each working alone and c is the time working together
1/8 + 1/10 = 1/c
Multiply by 40c to clear the fractions ( 40c is the least common multiple)
40c(1/8 + 1/10 = 1/c)
5c + 4c = 40)
9c = 40
Divide by 9
9c/9 = 40/9
c =4 4/9 minutes
Answer:
4.5
Step-by-step explanation:
Answer:
646.0 cm^3
Step-by-step explanation:
The volume of this cube with side length 8 cm is (8 cm)^3, or 512 cm^3.
The volume of the hemisphere (half sphere) is
V = (1/2)(4/3)(pi)(4 cm)^3 (since half of the diameter, 8 cm,
V = (2/3)(3.14)(64 cm^3), or is the radius)
V = 133.86 cm^3, or approximately 133.9 cm^3.
The volume of the entire solid is (512 + 133.9) cm^3, or 646.0 cm^3
