A rational number is a number that can be written into a fraction. pi, some square roots, e, etc. are irrational numbers(opposite of rational numbers)(numbers that cannot be written into a fraction).
Thanks for your question!
First thing we have to do here is take t to the other side by multiplication:
rx + sx = t
Now, group together, x as the GCF:
x(r+s) = t
Now, divide
x = t/(r+s)
Hope this helps!
Answer:
-34
Step-by-step explanation:
-90+56= -34
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
