Question

In order to remove noxious weeds from his property, a farmer sprays a weedicide over it. The chemical is slow-acting, and the number of weeds per hectare remaining after t days is given by N = 20 + 100 / (t+2). How many weeds per herb would be alive after 8 days"

Answer 1

After 8 days of applying the weedicide, there would be 30 noxious weeds per hectare remaining on the property.

Step-by-step explanation:

The question is concerned with the application of a mathematical formula to determine the remaining number of noxious weeds per hectare after a certain number of days, following the application of a weedicide. The provided formula for the number of weeds remaining is N = 20 + 100 / (t+2). To answer the inquiry, we substitute the time variable t with the specific value of 8 days.

N = 20 + 100 / (8+2)

The calculation then proceeds as follows:

• N = 20 + 100 / 10
• N = 20 + 10
• N = 30

Therefore, after 8 days, there would be 30 weeds per hectare still alive on the farm.
