Noah spent 24 hours working on his car.He spent 4/5 on his time working on his transmission.How much time did Noah spead working

Dimas [21]

Answer-

Noah spent 19 hours 12 minutes working on the transmission.

Solution-

Noah spent 24 hours working on his car.

He spent $\dfrac{4}{5}$ on his time working on his transmission and rest on other .

So the total time spent by Noah working on the transmission is,

$=24\times \dfrac{4}{5}\\\\=\dfrac{96}{5}\\\\=19\dfrac{1}{5}\ \text{hours}\\\\=19\ \text{hours}\ 12\ \text{minutes}$

Therefore, Noah spent 19 hours 12 minutes working on the transmission.

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

Mama L [17]

For this case we have that by definition, the equation of the line in a slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have the following equation:

$y = 2x + 2$

Thus, the slope is $m_ {1} = 2$

By definition, if two lines are perpendicular then the product of the slopes is -1.

$m_ {1} * m_ {2} = - 1$

We find $m_ {2}:$

$m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {2}$

Thus, the equation of the line is:

$y = - \frac {1} {2} x + b$

We substitute the given point to find "b":

$3 = - \frac {1} {2} 6 + b\\3 = -3 + b\\b = 6$

Thus, the equation of a line perpendicular to the given line and passing through the given point is:

$y = - \frac {1} {2} x + 6$

Answer:

$y = - \frac {1} {2} x + 6$
