The lowest common denominator for 15 and 12 will get in this way
15=3*5
12 = 3*4
LCM will be 3*4*5=12*5=60
Answer:
a=9, c=19
Step-by-step explanation:
Aight so basically in 30, 60, 90 triangles there is a formula for the sides
the hypotenuse(the longest side)=2a
The tiny side (the smallest side)=a
and the middle child =
Based on that we see that a is 9
and since c=2a then it's 18

Answer: The probability is about 0.2%.
The probability of flipping heads one time is 0.5, 50% or 1/2.
To flip heads 9 times in a row, we have to multiply 1/2 by itself 9 times.
(1/2)^9 = 1/512 or about 0.2%
It should only happen once every 512 times.
