Out of 30 questions, Ahmad answer 12 of them incorrectly. What percent of the questions did he answer correctly?

kati45 [8]

First, you would need to determine how many questions he got correct.
30 - 12 = 18

Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
$\frac{18}{30}$ = $\frac{x}{100}$

Now, you would cross multiply.
30x = 1,800

The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x = 60

Ahmad got 60% of the questions correct.

I hope this helps!

Find an equation of the plane consisting of all points that are equidistant from (-3, 5, -4) and (-5, 0, 4), and having -2 as th

Firdavs [7]

Answer:

-2x-5y+8z+4.5=0

Step-by-step explanation:

Let (x,y,z) be the coordinates of the point lying on the needed plane. This point is equidistant from the points (-3, 5, -4) and (-5, 0, 4), so

$d_1=\sqrt{(x-(-3))^2+(y-5)^2+(z-(-4))^2}=\sqrt{(x+3)^2+(y-5)^2+(z+4)^2}\\ \\d_2=\sqrt{(x-(-5))^2+(y-0)^2+(z-4)^2}=\sqrt{(x+5)^2+y^2+(z-4)^2}\\ \\d_1=d_2\Rightarrow \sqrt{(x+3)^2+(y-5)^2+(z+4)^2}=\sqrt{(x+5)^2+y^2+(z-4)^2}\\ \\(x+3)^2+(y-5)^2+(z+4)^2=(x+5)^2+y^2+(z-4)^2\\ \\x^2+6x+9+y^2-10y+25+z^2+8z+16=x^2+10x+25+y^2+z^2-8z+16\\ \\-4x-10y+16z+9=0\\ \\-2x-5y+8z+4.5=0$
