Answer:
23+12=
Step-by-step explanation:
you just need figure it out in your head and see what sounds right
Answer:
≈ 82 feet
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to calculate distance (d)
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here the hypotenuse is the distance (d) between the 2 poles, hence
d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )
d = 
≈ 82 feet ( to the nearest foot )
Answer:
I would say NO
Step-by-step explanation:
because if you look at those triangles, the one on they have two matching angles and two one side. The other angle in the triangle on the left isn't marked or anything so we can assume and the one on the right has no marked side. I hope I made a little sense. I don't know how to explain but I guess in short you could say that you don't have enough information to determine if they're the same
AGAIN!! I CAN'T PROMISE IF THIS IS RIGHT!!
Answer:
4 hours, 150 x 4 = 600 pls give brainliest
Answer:
Although the notation is sloppy, I will assume based on former questions of the same that "∑n=15[5(−2)^n−1]" translates mathematically to . Please correct me, though, if this in incorrect.
Anyway, there is neat formula that will deal with question very quickly. It is the following:
Sn is the sum of the geometric series
a1 is the first term in the series
r is the common ratio
n is the number of terms in the finite geometric series
Let's use this formula to our advantage! However, there are two variables that we do not know: a1 and n. Let's start with a1.The first term in the series is when n=1, so let's determine what that is.
