Answer:
n = 5
Step-by-step explanation:
180(n − 2) = s
180(n − 2) = 540
180n - 360 = 540
180n - 360 + 360 = 540 + 360
180n = 900
(1/180) 180n = 900 (1/180)
n = 5
(2x-24)/8
the only way to simplify it is divide every number by 2
(x-12)/4=(1/4)x-3
Probability is (outcome wanted)/(total possible outcomes). Total possible outcome is the whole area of the rectangle. Which is (18)(12)=216. The outcome wanted is just the area of the triangle. (0.5)(2)(5)=5. Now 5/216=0.02
Answer:
given the circumference is 30t.
Step-by-step explanation:
The circumference of a circle is 
and the area of a circle is 
assuming the radius is 
for the circle in question.
We are given the circumference of our circle is 
.
If we solve this for r we get: 
. To get this I just divided both sides by 
since this was the thing being multiplied to .
So now the area is 
.
Simplifying this:
.
30/2=15 so:
.
Squaring the numerator and the denominator:
Using law of exponents or seeing that a factor of 
cancels:
