Answer:
A: 144 cm
B: 64 cm
C: 36 cm
Step-by-step explanation:
The volume of a cone is given by ...
V = (1/3)πr²h
Solving for h, we get ...
3V/(πr²) = h
Filling in the given values, we get ...
3(192π)/(πr²) = h
576/r² = h
Then the heights of the different cones are ...
A: r = 2, h = 576/4 = 144 . . . cm
B: r = 3, h = 576/9 = 64 . . . cm
C: r = 4, h = 576/16 = 36 . . . cm
Answer:
0.125 and 1/8
Step-by-step explanation:
To convert a percentage to a decimal, divide by 100 to move 2 decimal places to the left.
12.50% / 100 = 0.125
To convert a percentage into a fraction, rewrite the decimal number you got and put it over 1. Multiply the numerator and denominator by 1000 to move 3 decimal places to the right and get your fraction.
· = 125/1000
Divide the numerator and denominator by the GCF, 125, to get your simplified fraction.
125/125 = 1
1000/125 = 8
125/1000 = 1/8
M = 4
n = 1
If you substitute in your values, you can see that 4 + 1 = 5
And 4 - 1 = 3

Answer:
y-b/x = a
Step-by-step explanation:
y-b/x = a
Add the two speeds together, then divide the two, this gives the average speed. Hope this was helpful!
