please help me.... A painting company charges $250 base plus $16 per hour. Another painting company charges $210 base plus $18 p
dem82 [27]
Basically its 250 + 16x = 210 + 18x where x = the number of hours doing the job.

Solving, we get 40 = 2x, x =20

The jobs has to be 20 hours long in order for their two painting jobs to be equally priced.

Hope this helped!

Determine the line that is perpendicular to y = 1/9x - 2/3
ANTONII [103]

Answer:

A

Step-by-step explanation:

Perpendicular lines have a relationship between their slopes. Their slope are negative inverses of each other. This means is one is 3 then the negative reciprocal is the other or -1/3. The slope here is 1/9 so the perpendicular slope is -9. Slope is always attached to the x term so A is the solution.

For the point P (-17,25) and Q(-10,30), fins the distance d(P,Q) and the coordinates of the midpoint M of the segment PQ.
Nonamiya [84]

Answer:

Distance = 8.6

M = (-13.5,27.5)

Step-by-step explanation:

Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2

= \sqrt{(-10_ }- (-17)_{ })^2 + (30_{ }- 25_{ })^2

= \sqrt{(-10_{ }+ 17_{ })^2 + 5^2_

= \sqrt{7^2+5^2}

= \sqrt{49+25}

= \sqrt{74}

= 8.6

Midpoint = (\frac{x_{2}+x_{1}}{2};\frac{y_{2}+y_{1}}{2})

= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2

= -27 ÷2 ; 55 ÷ 2

= -13.5, 27.5

Solve for the missing angle. Round to the nearest hundredth.<br> 18<br> ?<br> 13<br> ? =<br> degrees
skad [1K]

Answer:

\theta \:=43.76^{\circ \:\:}

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

  • The adjacent to Ф = 13
  • The hypotenuse = 18

so

cos Ф = adjacent/hypotenuse

cos\:\theta \:=\frac{13}{18}

\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)

   =43.76^{\circ \:}

Therefore, the missing angle is:

\theta \:=43.76^{\circ \:\:}
