Well as a cashier he earns 9$ an hour, so if he works 11 hours he will earn 99$ and he earns 10.75$ an hour because 129 divided by 12 is 10.75 and since he earns 10.75 for a grocery stocker he will earn 182.75 for working 17 hours. in total he earns 281.75$.

What is the equation of the line that passes through (6, 1) and is perpendicular to the line y 3x+2? CI) At what angle do the li

Andrews [41]

Answer with explanation:

The equation of any line with slope 'm' and passing through any point $(x_1,y_1)$ is given by

$y=mx+(y_1-mx_1)$

As we know that the general equation of a line with slope 'm' is $y=mx+c$

Comparing with the given equation $y=3x+2$ we can conclude slope of the given line is $m_1=3$

Now we know that the product of slopes of perpendicular lines is -1

Mathematically we can write for perpendicular lines

$m_1\times m_2=-1$

Thus the slope of the required line is obtained from the above relation since it is given that they are perpendicular

$3\times m_{2}=-1\\\\\therefore m_{2}=\frac{-1}{3}$

Hence using the given and the obtained values the equation of the required line is

$y=-\frac{1}{3}x+(1-\frac{-1}{3}\times 6)}\\\\y=\frac{-x}{3}+3$

Part b)

The angle of intersection between 2 lines with slopes $m_{1},m_2$ is given by

$\theta =tan^{-1}(\frac{m_2-m_1}{1+m_1m_2})$

Comparing the equations of given lines

$y=6x+3\\\\y=2x+3$

with the standard equation we get

$m_{1}=6\\\\m_{2}=2$

Thus the angle of intersection becomes

$\theta =tan^{-1}(\frac{2-6}{1+2\times6})=17.10$

is Justin went shopping for school clothes if the item cost $150 and he received a 10% discount what is the final price of his p

ASHA 777 [7]

Answer:

$135

Step-by-step explanation:

We can answer this by multiplying $150 by (1.00 - 0.10), or by 0.90:

0.90($150) = $135.

Note that 1.00($150) = $150 (full price)

and that 0.10($150) = $15 (discount)

and that (0.90)($150 = $135 (the fastest way to calculate the final (sale) price.
