When dividing fractions, flip the 2nd one around and then multiply across:

a) 3/11 / 3/11 = 3/11 x 11/3 = 33/33 = 1

b) 9/10 / 3/5 = 9/10 x 5/3 = 45/30 = 1 15/30 = 1 1/2

Answer:

1 and 3/2 or 1 and 1 1/2

Step-by-step explanation:

3➗3=1 and 11➗11= 1 so a. is 1/1 or 1.

9/10➗3/5 or 9➗3=3 and 10➗5=2 so it is 3/2 or 1 1/2 so the answers are 1 and 1 1/2! Hope this helps.

What is the standard form of the equation of a line for which the length of the normal segment to the origin is 8 and the normal
jeka57 [31]
Slope of line = tan(120) = -tan(60) = - &radic;3
Distance from origin = 8

Let equation be Ax+By+C=0
then -A/B=-&radic;3, or
B=A/&radic;3.
Equation becomes
Ax+(A/&radic;3)y+C=0

Knowing that line is 8 units from origin, apply distance formula
8=abs((Ax+(A/&radic;3)y+C)/sqrt(A^2+(A/&radic;3)^2))
Substitute coordinates of origin (x,y)=(0,0)  =>
8=abs(C/sqrt(A^2+A^2/3))
Let A=1 (or any other arbitrary finite value)
solve for positive solution of C
8=C/&radic;(4/3) => C=8*2/&radic;3 = (16/3)&radic;3

Therefore one solution is
x+(1/&radic;3)+(16/3)&radic;3=0
or equivalently
&radic;3 x + y + 16 = 0

Check:
slope = -1/&radic;3  .....ok
distance from origin
= (&radic;3 * 0 + 0 + 16)/(sqrt(&radic;3)^2+1^2)
=16/2
=8  ok.

Similarly C=-16 will satisfy the given conditions.

Answer  The required equations are
&radic;3 x + y = &pm; 16 
in standard form.

You can conveniently convert to point-slope form if you wish.
