Let x = the number of hours Eva needs to complete the job
and y = the number of hours Emily needs to complete the job
x = 6
1/x + 1/y = 1/4
(The amount of work Eva does in 1 hr + the amount of work Emily does in 1 hr should equal 1/4 of the total work)
1/6 + 1/y = 1/4
1/y = 1/12
y = 12 hours
Emily would take 12 hours to do it by herself.
Answer: 0.29 or 29 cents each :)

Cos α = sin (90-α) so cos 19 = sin 90-19 = sin 71
The volume of the larger cone is equal to the total volume of the two smaller cones
<h3>How to compare both cones?</h3>
From the question, we have two equal cylinders.
This means that the cylinders have equal volume.
From the complete question, a large cone is placed in one of the cylinders, while two small cones are placed in the other.
Since the cylinders have equal volumes, then the volume of the large cone equals the sum of the volumes of the smaller cones.
Hence, the volume of the larger cone is equal to the total volume of the two smaller cones
