25% of people leave early as 6 is 1/4 of 24. You can solve this by dividing 6 by 24 (I believe, maybe check with someone on that but that’s how i figured it out).
The cone equation gives

which means that the intersection of the cone and sphere occurs at

i.e. along the vertical cylinder of radius

when

.
We can parameterize the spherical cap in spherical coordinates by

where

and

, which follows from the fact that the radius of the sphere is 3 and the height at which the sphere and cone intersect is

. So the angle between the vertical line through the origin and any line through the origin normal to the sphere along the cone's surface is

Now the surface area of the cap is given by the surface integral,




Answer:
no. because they are bot equivalent ratios or proportions
Answer:
89:120
Step-by-step explanation:
convert the both times to minutes
2 hours is 120 mins
89:120
both divisible by 1
89:120
it cant be simplified further
To get a number to decrease by 21% you multiply it by 0.79 (1-0.21)
r = 0.79
