bearing in mind that perpendicular lines have <u>negative reciprocal</u> slopes, let's find firstly the slope of AC.

so, we're really looking for the equation of a line whose slope is 1/5 and that passes through (3,3)
Answer: 10204 millimeters
Step-by-step explanation: A gallon = 3875 mm. A quart is 946. 946x 3 = 2838. A pint is around 473 mm which, when multiplied by 7, is 3311. Finally, there are 6 ounces which are approximately 30 mm. 6x30 = 180. We add all of this up : 3875 + 2838+ 3311 + 180 = 10204.
Answer:
x = 2.4
Step-by-step explanation:
Corresponding sides of the similar triangles are proportional:
x/(x+3) = 8/18
18x = 8(x +3) . . . . . multiply by 18(x+3)
10x = 24 . . . . . . . . subtract 8x
x = 2.4 . . . . . . . . . . divide by 10
The sum oh p 3/4 should be 3.333
