170 170 170 170 170 170 170
Answer:
D
Step-by-step explanation:
The answer is A because everything else is a statistic. it literally has percent at the beginning of all of them
Y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m
so
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so
points (-2,3) and (3,0)
slope is (0-3)/(3-(-2))=-3/(3+2)=-3/5
a point is (3,0) Or (-2,3)
so it could be
y-0=-3/5(x-3) or y-3=-3/5(x-(-2)) which is equal to y-3=-3/5(x+2)
that's the answer
B is answer
Let being these two angles : angle A and angle B
we know that complementary angles assumed make 90 degree so
m<A +m<B = 90 degrees
and given again angle A is proportional inverse by 0,25 and angle B by 0,1(6)
A = 0,25 *x
B = 0,1(6)*x
A+B=90
0,25x +0,1(6)x =90
x(0,25 +0,1(6)) = 90
x(0,41(6))=90
x = 90/(0,41(6)) = 216,3
measure angle A = 0,25*216,3 = 54,075 degrees
measure angle B = 90 -54 = 36 degrees
