X would end up being 80

6 0

Okay so 30% = 42 that means 90%= 42+42+42= 126 now we need 10%

10%=4.2 126+4.2= 130.2 Hope this helped

The one with less zeros IN FRONT is bigger, but if the zeros are behind the number the most zeros would be bigger, so the answer is 0.001

Answer:

$y=\frac{1}{25}x-\frac{31}{25}$

Step-by-step explanation:

$y=-25x-5$

You can get the gradient of the line perpendicular to this as you know the products of their gradients will be -1.

$-25*m_{perpendicular}=-1\\m_{perpendicular}=\frac{1}{25}$

We have a gradient, and a point (6, 1), so we can now substitute our known values into the line equation.

$(y-y_0)=m(x-x_0)$

$y-1=\frac{1}{25} (x-6)$

Rearrange for y and collect terms.

$y=\frac{1}{25}x-\frac{6}{25}-1\\\\y=\frac{1}{25}x-\frac{31}{25}$
