Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio
Answer:
a) 15.28 hours
Step-by-step explanation:
535/-35
≈-15.28
but time is always positive so it would take him 15.28 hours
Answer:
3+(-4)= -1
Step-by-step explanation:
Originally on 3 and goes to -4, and for addition add (-4) to positive 3 and you'll get -1
We know from table that x intercept (when y or t(x) is 0) is -3
next we can move over the -y from the given equation
y = 4+ 4x
solving for when y is 0
0 = 4 + 4x
-4 = 4x
x=-1
Thus the first equation has larger intercept of -1
Since this is a permutation, it would be 5!(factorial)
so 5x4x3x2x1
