Slope of line perpendicular to ax+by=c is b/a
given
-2x-8y=18
slope of perpendicular is -8/-2=4
y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b
y=4x-15
Answer:
If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.
Step-by-step explanation:
a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

300 people are the answer.Explanation:
Percent means per 100 numbers of unitso 27 % means 27 numbers people out of per 100 Number peopleSince 27 people chose salad out of 100 Number people so what numbers of total people if 81 people choose in actual27 Nos from 100 Number81 Nos ???100*81/27=300
8640 minutes/60 minutes per hr=144 hours
144 hours/24 hrs a day=6 days
Final answer: A
