Answer:

C. 30

Step-by-step explanation:

15 men do work in 16 days

This means that 7.5 men (15/2) would do that same work in 32 days (16x2).

If the number of men increase, the amount of days decrease.

8 men would do that work in 30 days

8 men > 7.5 men

30 days < 32 days

Answer:

Option c.

Step-by-step explanation:

It is an inverse proportion, fewer workers more days to finish the job.

15 -----16

8 ----- x

x = (16)(15)/8 = 240/8 = 30 days

Hope this helps

he height of a cone-shaped container is 70 centimeters and its radius is 15 centimeters. Cathy fills the container completely wi
Rus_ich [418]
Let's restate the given:

Height of cone = 70 cm
Radius = 15 cm

Now, first, let's find the volume of the cone through the formula V = πr²h/3
Substitute all data and you will get 16493.36 cubic centimeters. 

Now, to get how many days the container will be complete empty, you simply divide the volume of the cone by 500 cubic centimeters.

Days = 16493.36 cu cm/ 500 cu cm
Days = 32.99 or 33 days. 

Thus, the answer you're looking for is 33 days.
