The area of the triangle is 4.75.
You times 1.9 (the height) and 5 (the base) then divide the product by 2.
A = 1.9km x 5km / 2
I think you mean GCF, or greatest common factor, in which case, yes, this is always true. An odd number has no factors of 2 or multiples of 2, so there is no way a factor of an odd number can be divisible by 2. Even if the even number has no odd factors, That would simply mean they have no common factors greater than 1, so the GFC would just be 1.
Answer:
The first time you pick a three the probability is 
but if you already pick a three then the probability of you picking a 3 again is 0 because you only have one 3.
Answer:
20x^50
Step-by-step explanation:
The sequence:
a 1 = 30, a 2 = 70, a 3 = 110, a 4 = 150, a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 = 30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.
