Nirmala graphed the relationship between the duration (in hours) of using an oil lamp and the volume (in milliliters) of oil rem
mariarad [96]

Answer:

Nirmala can use the lamp for 31.66 hours before it runs out of oil.

Step-by-step explanation:

From the graph,

Take any two points, let say

(15, 25)

(25, 10)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(15,\:25\right),\:\left(x_2,\:y_2\right)=\left(25,\:10\right)

m=\frac{10-25}{25-15}

m=-\frac{3}{2}

The equation of line in slope-intercept form

y = mx + b

Putting m=-\frac{3}{2}  and any point, let say (25, 10), to find the y-intercept 'b'

10=-\frac{3}{2}\left(25\right)+b

-\frac{3}{2}\left(25\right)+b=10

-\frac{75}{2}+b=10

\mathrm{Add\:}\frac{75}{2}\mathrm{\:to\:both\:sides}

-\frac{75}{2}+b+\frac{75}{2}=10+\frac{75}{2}

b=\frac{95}{2}

b=47.5

So the equation of line will be:

y = mx + b

y=-\frac{3}{2}x+47.5

In order to find how long Nirmala can use the lamp before it runs out of oil, we need to find x-intercept which can be obtained by putting y = 0, and solve for x, as duration lies on x-axis.

so

y=-\frac{3}{2}x+47.5

Putting y = 0

0=-\frac{3}{2}x+47.5

-\frac{3}{2}x+47.5=0

-\frac{3}{2}x=-47.5

\mathrm{Multiply\:both\:sides\:by\:}2

2\left(-\frac{3}{2}x\right)=2\left(-47.5\right)

-3x=-95

\mathrm{Divide\:both\:sides\:by\:}-3

\frac{-3x}{-3}=\frac{-95}{-3}

x=\frac{95}{3}

x=31.66

Therefore, Nirmala can use the lamp for 31.66 hours before it runs out of oil.
