If 60% of the painters is 12, then 10% of the painters is 2, and therefore there are 20 painters.

12 painters ----- 60% of the painting crew
x painters ------- 100% of the painting crew
____________________________________
12*100%=x*60%
12*1=x*0,6
12=0,6x
x=20

20 painters worked on this job :)

What is an equation of the parabola with vertex at the origin and focus (0, 0.75)?

morpeh [17]

Answer:

$x^{2} =3y$

Step-by-step explanation:

Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form

$x^{2} =4py$

Because the parameter $p$ is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.

Replacing the parameter value, we have

$x^{2} =4(0.75)y\\x^{2} =3y$

Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is $x^{2} =3y$ .

Please help me out ‼️

Westkost [7]

Answer:

Step-by-step explanation:

In similar triangles, corresponding elements are proportional. Then we get,

(2x + 1)/(x-1) = 10/4

4(2x +1) = 10(x-1)

8x + 4 = 10x - 10

8x = 10x - 14

2x = 14

x = 7

Hope it helps and if it does, please mark me brainliest...

Show that y2+ x-3 =0 is an implicit solution to dy/dx =-1/ (2y) on the interval (- [infinity] , 3)

Sedaia [141]

Answer:

Implicit function

$\frac{d y}{d x} = \frac{-1}{2y}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given y² + x - 3=0 ...(i)

Differentiating equation (i) with respective to 'x', we get

$2 y \frac{d y}{d x} +1 = 0$

⇒ $2 y \frac{d y}{d x} = -1$

⇒ $\frac{d y}{d x} = \frac{-1}{2y}$

$\frac{d y}{d x} = \frac{-1}{2 (3)}$

$\frac{d y}{d x} = \frac{-1}{6}$
