Answer:
469.58
Step-by-step explanation:
484.10 decrease 3% =
484.10 × (1 - 3%) = 484.10 × (1 - 0.03) = 469.577
If the slope of line C is -4, the slope of line D, which is perpendicular to C, is the negative reciprocal of the slope of C: -( 1 / (-4) ), or +1/4.
Note how 1/4 is the native reciprocal of -4, and that -4 is the negative reciprocal of 1/4.
The slope of line D is 1/4.
The 
-coordinate of the center of mass is the average value of 
over the plate, given by the ratio of the integral of 
to the mass of the plate.
The mass of the plate is
while the integral of 
over the plate is
and the -coordinate of the center of mass is
Answer:
x=13
Step-by-step explanation:
one angle of triangle=85
parallel lines and vertical angles
the second angle is 82:
sum of angles of the triangle=180
x+85+82=180
x+167=180
x=180-167
x=13
