1 length is 4.75 feet
42 lengths = x feet Cross multiply
1 * x = 42 * 4.75 Multiply on the right
x = 199.5
amount left = amount started with - amount amount used
Amount left = ???
Amount started with = 240 feet.
Amount used = 199.5 Substitute
Amount left = 240 - 199.5 Subtract
Amount left = 40.5 Answer
first, we can find the slope from the equation that is given buy solving the equation for y
3x+2y = 6
2y = 6-3x
y = 3-3/2x
y = -3/2x+3
now that the equation is in slope-intercept form, we can easily see that the slope of the given line is -3/2
perpendicular lines have slopes that are negative reciprocals, so we can just take the negative reciprocal of the slope we have
-3/2 → 3/2 → 2/3
the slope of the perpendicular line is 2/3
hope this helped
