We can set up a proportion to find the answer.

\frac{9}{x} = \frac{30}{100}

Cross multiply

9(100) = 30x

Solve for x

x =  \frac{900}{30}

x = 30

So 9 is 30% of 30.

The answer is 30.

Line up % with % and number with number

30% is 9
100% is ?

Those numbers are in proportion so we can cross multiply to find the missing part of the proportion.

?=100•9/30=30

So 30% of 30 is 9

What is the equation of the line perpendicular to y=2x+3.14 going through the points (2,4)?
inessss [21]

Answer:

x+2y-10=0

Step-by-step explanation:

Consider an equation: y=mx+c

Here, m is the slope of the line and c is the y-intercept.

Given equation is y=2x+3.14

Here, slope is m=2

As product of slopes of two perpendicular lines is equal to -1, slope of the required line is m_1=\frac{-1}{m}=\frac{-1}{2}.

Let (x_1,y_1)=(2,4)

Equation of the required line is y-y_1=m_1(x-x_1)

y-4=\frac{-1}{2}(x-2)\\2(y-4)=-1(x-2)\\2y-8=-x+2\\x+2y-8-2=0\\x+2y-10=0
