Answer:
It takes Michael 1 hour, 14 minutes and 7 seconds to seal the driveway close
Step-by-step explanation:
Hi
Leon do the work in 17 hours that means the rate of his work is
, so he do
of the work in two hours, therefore Michael do the other
of the work, thus Michael rate will be
.
So it takes Michael
to complete the work, or ![\frac{4h}{17} \times \frac{60min}{1hour} =14\frac{2}{17} min\\\\\frac{2}{17} min \times \frac{60 secs}{1min}=7secs](https://tex.z-dn.net/?f=%5Cfrac%7B4h%7D%7B17%7D%20%5Ctimes%20%5Cfrac%7B60min%7D%7B1hour%7D%20%3D14%5Cfrac%7B2%7D%7B17%7D%20min%5C%5C%5C%5C%5Cfrac%7B2%7D%7B17%7D%20min%20%5Ctimes%20%5Cfrac%7B60%20secs%7D%7B1min%7D%3D7secs)

Answer:
![\bold{m=-\dfrac16}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D-%5Cdfrac16%7D)
Step-by-step explanation:
![\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}](https://tex.z-dn.net/?f=%5Cbold%7Bslope%5C%2C%20%28m%29%3D%5Cdfrac%7Bchange%5C%20in%5C%20Y%7D%7Bchange%5C%20in%5C%20X%7D%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%7D)
(1, 3) ⇒ x₁ = 1, y₁ = 3
(7, 2) ⇒ x₂ = 7, y₂ = 2
So the slope:
![\bold{m=\dfrac{2-3}{7-1}=\dfrac{-1}6=-\dfrac16}](https://tex.z-dn.net/?f=%5Cbold%7Bm%3D%5Cdfrac%7B2-3%7D%7B7-1%7D%3D%5Cdfrac%7B-1%7D6%3D-%5Cdfrac16%7D)
The answer is 28 for the volume
