Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67

Hence, the car wash uses 22.67 containers of wax per day.

Find the exact distance between the line 6x-y=3 and the point (6,2). Show your work. Explain your answer.
Serggg [28]

Answer:

The distance of point ( 6 , 2 ) from line  6 x - y = 3 is  \frac{31}{\sqrt{37} }  unit .

Step-by-step explanation:

Given as :

The equation of line is 6 x - y = 3

And The points is ( 6 , 2 )

Let The distance between the line and points is d unit

So, The distance of point from the line = \frac{\begin{vmatrix}ax & +b y & + c\end{vmatrix}}{\sqrt{a^{2}+b^{2}}}

Or, d = \frac{\begin{vmatrix}6\times x & +(-1)\times  y & + (-3)\end{vmatrix}}{\sqrt{6^{2}+(-1)^{2}}}

Or, d =  \frac{\begin{vmatrix}6\times 6 & +(-1)\times  2 & + (-3)\end{vmatrix}}{\sqrt{6^{2}+(-1)^{2}}}

Or, d = \frac{36 - 2 - 3}{\sqrt{37} }

∴    d = \frac{31}{\sqrt{37} }  unit

Hence The distance of point ( 6 , 2 ) from line  6 x - y = 3 is  \frac{31}{\sqrt{37} }  unit .   Answer

Answer:   \bold{C)\ -\dfrac{1}{2}}

<u>Step-by-step explanation:</u>

.\qquad \dfrac{x+2}{15}=\dfrac{x+1}{5}\\\\\\\rightarrow (15)\dfrac{x+2}{15}=\dfrac{x+1}{5}(15)\\\\\\\rightarrow x+2=3(x+1)\\\\\rightarrow x+2=3x+3\\\\\rightarrow \qquad 2=2x+3\\\\\rightarrow \qquad -1=2x\\\\\rightarrow \qquad -\dfrac{1}{2}=x

(PLEASE HELP!!) Use the following diagram to answer the questions.
monitta

Answer:

x:

5x - 29 = 3x+ 19

2x = 48

x = 24°

Angle 1:

180 - (3x+7) = 180 - 79 = 101°

Angle 2:

3x + 7 = 79°

Angle 3:

Same as Angle 1 = 101°

Angle 4:

Same as Angle 1 = 101°

Angle 5:

Same as Angle 2 = 79°

Angle 6:

Same as Angle 5 = 79°

Angle 7:

180 - (5x - 29) = 180 - 91 = 89°

Angle 8:

Same as Angle 7 = 89°

Angles 2 and 3 are Supplementary angles
