Aconstruction company needs to remove tons of dirt from a construction site. they can remove tons of dirt each hour. how long will take to remove the dirt.

Question:

A construction company needs to remove 24 tons of dirt from a construction site. They can remove 3/4 tons of dirt each hour. How long will it take to remove dirt

It takes 32 hours to remove the dirt

Step-by-step explanation:

Given:

Total amount dirt to be removed =   24 tons

Dirt that can removed in one hour =  3/4 tons

To Find:

Time taken to remove all the dirt =?

Solution:

Let the time taken to remove the dirt from the company be x.

Then

x =  

Substituting the given values , we get

x =

x =

x =

x= 32

; )

step-by-step explanation: ; )

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
