18.36 is the answer.
27 divided by 100 is .27
100-32 is 68, so you need to find 68 percent of 27.
.27 id 1% of 27, so you can easily multiply it by 68 and get 18.36

ABCD is rectangle on a coordinate grid with side AB parallel to side CD. Side BC is perpendicular to AB. The slip of AB is 3/4.
dybincka [34]

The slope of BC is \frac{-4}{3}

Step-by-step explanation:

Let us revise some notes about slopes of lines

  • If two lines are parallel, then their slopes are equal
  • If to lines are perpendicular, then the product of their slopes is -1, that means if the slope of one is m, then the slope of the other is \frac{-1}{m}

∵ ABCD is a rectangle

∵ AB // CD

∴ The slope of AB = the slope of CD

∵ BC ⊥ AB

∴ The slope of BC × the slope of AB = -1

∵ The slope of AB = \frac{3}{4}

- To find the slope of BC reciprocal the slope of AB and reverse its sign

∴ The slope of BC = \frac{-4}{3}

The slope of BC is \frac{-4}{3}
