What percent of 50 is 9?
d1i1m1o1n [39]
9 is 18% of 50. So, 50 percent also written as 50% means 50 out of 100 parts. Since there are exactly two 50s in 100, fifty percent is the same number as one half. 50 percent=0.5 in but as a fraction, its 1/2.

What is the slope of a line perpendicular to the line whose equation is 9x+6y=18
Luba_88 [7]

answer:

slope: -2/3

step-by-step explanation:

y=mx+b

m represents the slope, and b the y-intercept.

rearrange: 9x= -6y+18

---> -6y= -9x-18

divide all terms by -6.

-6y/-6= -9/-6x-18/-6

y= 3/2x+3 (slope/intercept form)

m= 3/2

---> 1/3/2= -2/3
