The perpendicular line will have a slope of b/a.
To find this, we first have to solve our equation for slope intercept form.
ax + by = c ----> subtract ax
by = -ax + c ----> divide by b
y = -a/bx + c/b.
So we know the slope of this equation to be -a/b. Since perpendicular lines have opposite and reciprocal slopes, we know we can simply flip the fraction and make it a negative to get the new slope of b/a.
Answer:

Step-by-step explanation:
Given equation:

Divide both sides by 5:

Cube both sides:




Add 4 to both sides:

Divide both sides by 3:

I think it's 138 Long by 109.5 more accurate .
92/73 = 1.26
120/100 = 1.2
138/109.5 =1.26
Hence 138 by 109.5 is more proportionate
The answer is A. 8/243
There are in total 18 objects:
6 nuts + 8 bolts + 4 screws = 18 objects
The probability of choosing a nut is: 6/18 (since there are 6 nuts of total 18 objects).
The probability of choosing a bolt is: 8/18 (since there are 6 bolts of total 18 objects).
The probability of choosing a screw is: 4/18 (since there are 4 screws of total 18 objects).
Because replacement occurs each time, there are always 18 objects. Also, since selecting a nut, a bolt, and a screw occurs together, we will use the multiplication rule and multiply the probabilities of events occurring together:
