Answer:
scalene acute
Step-by-step explanation:
Lets put this into an equation
x + 1/5 * x = 36
1.2x = 36
x = 30
1/5x = 6
So our final answer is 6 and 30.

Answer:
B: 2⁷-1 = 127
Step-by-step explanation:
A Mersenne prime is a prime of the form 2^n -1, where n is also a prime.
Among the answer choices, neither 90=2·3²·5 nor 15=3·5 is prime. Both 2⁷-1 = 127 and 2¹¹-1 = 2047 are of the right form, but 2047 = 23·89 is a composite number.
2⁷-1 = 127 is a Mersenne prime
Our angle teta is:
teta = 3pi/4
since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)
sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.
cos(3pi/4) = -√2/2
tan(3pi/4) = -1
The problem says that 2500 people went, out of all the answers choices which choice gives you the total of 2500 when you add the adults and children.
Answer is B because 1100 + 1400 = 2500
