Answer:
negative reciprocal
Step-by-step explanation:
16
––
30
because there are 30 inches in all and 16 out of the 30 are concrete
notice, the x-coordinate is the same for both points, thus is a vertical line.
Check the picture below.
Answer:
g=3
Step-by-step explanation:
4(g+6)=36
4g+24=36
-24 -24
4g=12
/4 /4
g=3
Check:
4(3+6)=36
4*9=36
36=36
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
